Informationsöverbelastning blir alltmer vanligare i den ständigt uppkopplade värld vi män- niskor lever i. Smarttelefonen skickar hela tiden ut notiser och information när någonting nytt sker till sina användare och den här utveckling har bidragit till att människor distraheras från viktiga livshändelser och effekterna kan resultera i tappat fokus, stress, depression och ut- brändhet. Syftet med det här kandidatarbetet är att skapa en designmetod som kan reducera informa- tionsöverbelastning. Vi har skapat en prototyp för ett socialt nätverk där användarna kan filtr- era innehållet i det sociala nätverket genom en filterfunktion. Användarna kan skapa nya fil- ter, aktivera samt avaktivera och byta mellan de skapade filtren för att stänga ute information som inte är relevant för stunden. Genom vår gestaltning undersöker vi om informationsöver- belastningen går att reducera genom kontextmedvetna system i mobilapplikationer där sys- temet känner av din kontext och därefter kan filtrera bort irrelevant information som du inte behöver ta del av just nu. Vi påpekar även säkerheten i sådana system och hur det kan kränka din integritet. / Information overload is becoming more common in the constantly connected world in which people live in. The smartphone constantly sends notifications and information to its users when something new happens, and this development has contributed to distracting people from vital life events, and the effects can result in lost focus, stress, depression and getting burned out. The main purpose of this Bachelor thesis is to create a design method that can reduce infor- mation overload. We have created a social network prototype where users can filter the con- tents of the social network through a filter function. Users can create new filters, enable and disable filters which then enables the user to filter out information that is not vital at the mo- ment. Through our prototype we examine whether information overload can be reduced through context aware systems in mobile applications, where the system recognizes your con- text and can filter out none vital information that you do not need to access at the moment. We also point out the security of such systems and how it may violate the users privacy.

In military battlefield domain, decision making plays a very important part because safety and protection depends upon the accurate decisions made by the commanders in complex situations. In military and defense applications, there is a need of such technology that helps leaders to take good decisions in the critical situations with information overload. With the help of multi-sensor information fusion, the amount of information can be reduced as well as uncertainties in the information in the decision making of identifying and tracking targets in the military area.   Information fusion refers to the process of getting information from different sources and fusing this information, to supply an enhanced decision support. Decision making is the very core and a vital part in the field of information fusion and better decisions can be obtained by understanding how situation awareness can be enhanced. Situation awareness is about understanding the elements of the situation i.e. circumstances of the surrounding environment, their relations and their future impacts, for better decision making. Efficient situation awareness can be achieved with the effective use of the sensors. Sensors play a very useful role in the multi-sensor fusion technology to collect the data about, for instance, the enemy regarding their movements across the border and finding relationships between different objects in the battlefield that helps the decision makers to enhance situation awareness.   The purpose of this thesis is to understand and analyze the critical issue of uncertainties that results information in overload in military battlefield domain and benefits of using multi-sensor information fusion technology to reduce uncertainties by comparing uncertainty management methods of Bayesian and Dempster Shafer theories to enhance decision making and situation awareness for identifying the targets in battlefield domain.

De tekniska system som tävlar om förarens uppmärksamhet i bilar och lastbilar ökar både i antal och komplexitet. Detta kanske inte är ett problem på en rak, lugn motorväg men minskar fokus på själva körningen och om något oväntat skulle hända kan konsekvenserna bli allvarliga eftersom föraren är distraherad och kan behöva ta in för mycket information på en gång. Syftet med projektet var att utveckla ett system för att presentera endast relevant och önskad information till förare av lastbilar och bussar i kritiska trafiksituationer. Detta för att göra det möjligt för föraren att fokusera mer på körningen och därigenom göra den säkrare och bekvämare. Å ena sidan ska systemet upptäcka vilken typ av trafiksituation lastbilen befinner sig i. Å andra sidan ska det avgöra vilken typ av information som skulle vara relevant för föraren i den situationen. Med en litteraturstudie, insamlad statistik, intervjuer och författarnas åsikter som grund identifierades ett antal händelser (som telefonsamtal och förekommande varningar) som kan inträffa i förarhytten på en lastbil och hur mycket de vardera skulle öka förarens arbetsbörda (workload). Detsamma gjordes för ett antal vanliga trafiksituationer som kan betraktas som kritiska och kräver mer uppmärksamhet än att bara köra rakt fram. Dessa händelser och situationer betygsattes därefter utifrån hur mycket de skulle öka belastningen på de sinnen som används mest i en körsituation, nämligen: synen, hörseln, motoriken och kognitionen. Matriser gjordes i vilka uppgifter och situationer ställdes mot varje sinne med betyg vilket senare användes som grund för de tre koncept som utvecklades för systemet. Koncepten hette Jigsaw, Fever och Three’s a crowd och utvärderades i en workshop på Scania. De två första realiserades i form av prototyper som gjordes i programmet GUIDE. Logiken som byggdes upp i programmet bestod av tillståndsmaskiner och med boolsk logik samt if- och while-slingor. / The technical systems that compete for drivers’ attention in cars and trucks are increasing both in numbers and complexity. This may not be a problem on a straight and sound highway but definitely decreases the focus on the actual driving and if something unexpected was to happen there could be dangerous consequences, due to too much distraction and information overload. The purpose of the project was to develop a system to present only relevant and desired information to drivers of trucks and busses in critical traffic situations, for the Swedish truck manufacturer Scania. This will enable the driver to focus more on the driving thus creating a safer and more comfortable driving situation. On one hand the system had to detect what type of traffic situation the truck is in. On the other hand it had to determine what type of information would be suitable for the driver in that situation. With a literature study, statistics, interviews and the authors’ judgments as a basis the project first identified a number of tasks (like phone calls and occurring warnings) that can take place in the cab of a truck and then assess how much they respectively would raise the workload of the driver. The same was done for a number of common traffic situations that were considered as critical and demanded more attention than just driving straight ahead. All these tasks and situations were graded on how much they would raise the load on the senses most used in a driving situation: visual, auditory, motor and cognitive. Matrices were made cross-referencing the tasks and situations with the grades on each modality and was used as the basis for the three concepts for the system that was developed. The concepts called Jigsaw, Fever and Three’s a crowd were evaluated in a workshop at Scania and the first two were realized in the form of prototypes which were made in the software GUIDE. The logic was made up of state machines and Boolean operators and if- and while-conditions.

Purpose: The purpose of this study is to investigate how influencer marketing is experienced by young adult women between the ages of 18 to 30, how the purchase intention is affected by their trust in, and trust in, influencers and influencer marketing as a marketing strategy and to see if there is fatigue of influencer marketing.  Research questions:  1. What do young adult women want to experience to make a purchase via influencer marketing on Instagram? 2. What is the attitude of young adult women towards influencer marketing in terms of trust and confidence? 3. How do young adult women react to the increasing prevalence of influencer marketing on Instagram? Methodology: A qualitative method has been applied to 20 informants. The semi-structured interviews took place on the video call application Zoom.  Theories: This study is based on six theories; eWOM, Influencer marketing, Trust and Confidence, Purchase intention, Theory of planned behavior and Information overload. Empiric: The empiric presents an interpreted view of the informants' answers in text.   Conclusion: The conclusions of this study are: 1. Young adult women have to feel a need, applicability to everyday life and the will to have, to feel that they want to make a purchase through influencer marketing. 2. Young adult women's attitudes to influencer marketing regarding trust and confidence vary from influencer to influencer and thus their buying intention in relation to influencer marketing is affected to varying degrees. 3. There is an oversaturation of influencer marketing on Instagram in young adult women aged 18 to 30 years / Syfte: Syftet med denna studie är att undersöka på vilket sätt influencer marketing upplevs av unga vuxna kvinnor i åldrarna 18 till 30 år, hur köpintentionen påverkas av deras förtroende för, och tillit till, influencers och influencer marketing som marknadsföringsstrategi samt att se om det finns en trötthet av influencer marketing  Forskningsfrågor:  1. Vad vill unga vuxna kvinnor uppleva för att genomföra ett köp via influencer marketing på Instagram?  2. Vad har unga vuxna kvinnor för inställning till influencer marketing i termerna tillit och förtroende? 3. Hur har unga vuxna kvinnor reagerat på den ökade förekomsten av influencer marketing på Instagram? Metod: En kvalitativ metod har tillämpats genom semistrukturerade intervjuer med 20 informanter. De semistrukturerade intervjuerna skedde via videosamtalsapplikationen Zoom.   Teori: Denna studie har utgått från sex teorier; eWOM, Influencer marketing, Förtroende och tillit, Köpintention, Teorin om planerat beteende och Informationsöverbelastning.  Empiri: I empirin presenteras en tolkad syn på informanternas svar i text.  Slutsats: Studiens slutsatser är: 1.

Det råder en trötthet av influencer marketing på Instagram hos unga vuxna kvinnor i åldrarna 18 till 30 år.

Urbanization has been a growing trend in the past fifty years. Cities are now transforming into smart cities, spaces whose infrastructure comprises an embedded digital layer. Hardware collects real-time data in the urban environment and software elaborates it to improve all types of services, from traffic to waste management to well-being. One technology that is expected to use this digital layer to further change the urban environment is the autonomous car. The purpose of this dissertation is to explore what key design attributes future autonomous cars should possess if they have not only to co-exist with and be accepted by people in the landscape of tomorrow’s smart cities, but also what they should not possess in order not to cause any harm. In this sense, the dissertation recognizes calm technology to be necessary in the design of a future autonomous car to support a human-centered, as opposed to a car- or technology-centered, environment. A socio-technical and systemic lens is applied to the phenomenological investigation of nine companies carried out by means of twelve in-depth semi-structured interviews with experts working within the automotive sector, the smart city industry, and calm technology. Eight attributes (safety, on-demand, geo-tracking, sharing, multiple purposes, communication through smart devices, electrical care and IoT/connectedness) are identified as necessary for future autonomous cars to implement in order to take advantage of the smart city infrastructure and provide a human-centered experience. Additionally, six out of the eight calm technology principles recognized in literature are considered necessary when designing future autonomous cars.

Information and the way of perceiving it are important for people, especially people with lower cognitive capabilities. According to previous studies, animation has the power of communicating and delivering the required message to different cognitive levels in simple and realistic methods. This qualitative study investigates the animation's role in alleviating information overload for people with lower cognitive skills, and explores the possibilities of using the animation as an alternative tool to the current methods of overload such as pictures and text. Data was collected through conducting interviews with caretakers, testing a prototype, and the second round of interviews. The findings indicated that animation in this field was positive and could surely be used as a future tool for providing information in their context. However, some considerations should be taken into account regarding how animation should be tailored to the users, such as the cognitive level differences and customizing the animation for instance.

There has been an increasing demand for commercial organisations to foster real-time interaction with customers, because harnessing customer competencies has been shown to be a major contributor towards various benefits, such as growth, innovation and competition. This may drive organisations to embrace the development of multimodal interaction and complement Electronic Customer Knowledge Management Systems (E-CKMS) with metaphors of audio-visual nature. Although the implementation of E-CKMS encounters several challenges, such as lack of trust and information overload, few empirical studies were devoted to assess the role of audio-visual metaphors, and investigate whether these technologies can be put into practice. Therefore, this thesis describes a comparative evaluation study carried out to examine the implication of incorporating multimodal metaphors into E-CKMS interfaces on not only usability of E-CKMS, but also the user¿s trust, knowledge and acceptance. An experimental E-CKMS platform was implemented with three different modes of interaction: Visual-only E-CKMS (VCKMS) with text and graphics, Multimodal E-CKMS (MCKMS) with speech, earcons and auditory icons and Avatar-enhanced multimodal E-CKMS (ACKMS). The three platforms were evaluated by three independent groups of twenty participants each (total=60) who carried out eight common tasks of increasing complexity and design based on three different styles. Another dependent group of forty-eight participants (n=48) was instructed to interact with the systems under similar usability conditions by performing six common tasks of two styles, and fill a questionnaire devised to measure the aspects of user acceptance. The results therein revealed that ACKMS was more usable and acceptable than both MCKMS and VCKMS, whereas MCKMS was more usable than VCKMS, but less acceptable. Inferential Statistics indicated that these results were statistically significant.

摘要 本研究從新奇追求動機探討遊客對旅遊產品的態度會被什麼因素所影響。許多學者提到，遊客對於新奇追求的差異，會影響他們選擇不同觀光活動及旅遊目的地的決策，因此旅遊行程有否提供遊客新奇的體驗（亦即新奇屬性）或是基於旅遊產品本身的新奇性，應能吸引不同新奇追求程度的遊客前往旅遊。然而以往關於新奇屬性的研究多針對實體產品，鮮少從服務性產品的面向做探討，文獻中對旅遊產品新奇性的描述亦甚少著墨，因此本研究藉由操弄新奇屬性和產品新奇性，從旅遊產品的角度觀察對於不同新奇追求程度的遊客之態度會產生什麼影響。 研究結果發現，旅遊行程加入新奇屬性或是產品新奇性較高的旅遊產品並不一定能讓遊客對有較好的印象。當面對無新奇屬性的旅遊行程或低新奇性產品（團體旅遊）時，低新奇追求的遊客相較於高新奇追求的遊客有更好的態度，但其同時對有新奇屬性的旅遊行程及高新奇性產品（自由行）也抱持同樣的好感；而面對有新奇屬性的旅遊行程或高新奇產品（自由行）時，高新奇追求的遊客則相對較有提升好感的趨勢。值得注意的是，當旅遊產品為高新奇性（自由行）並同時搭配具有新奇屬性的旅遊行程後，反而會使消費者發生資訊過載的情形進而提高學習成本，導致消費者對產品的評價混淆甚至產生負面態度。 因此，如果廠商想要在市場上推出新產品，以適度的新奇性做為產品設計的主軸是較為理想的選擇，例如自由行對於高、低新奇追求程度的消費者都具有一定的吸引力，或是團體旅遊搭配具有新奇屬性的旅遊行程亦是保險的組合方式。要注意的是，過多的新奇資訊同時也會增加消費者的學習成本，一旦造成消費者的資訊超載，反而會造成負面的效果。 / This research focuses on what factors based on novelty seeking will be influencing tourists’ attitude toward the tourism product. Many scholars have already mentioned that different degree of novelty seeking among tourists may influence their choices of different sightseeing activities and trip destination. Therefore, whether the travel programs provide novel experiences to the tourists(namely novel attributes) or any novelty of the product itself should be able to attract tourists with different degree of novelty seeking. However, researches on novel attributes in the past mostly put emphasis on substantial products and seldom discussed on service products. In addition, there is a lack of literature regarding product novelty as well. For these reasons, the purpose of this research is to observe the factors which influence attitudes of tourists with different degree of novelty seeking by means of manipulating novel attributes and product novelty. The result of this research shows that travel journey with novel attributes or just a tourism product with high degree of novelty don’t necessarily make better impressions on tourists. When facing travel journey with no novel attributes or just a product with low degree of novelty (package tour), tourists with low degree of novelty seeking show more favor towards the product than those with high degree of novelty seeking, but they as well have positive attitude when there is travel journey with novel attributes or just a product with high degree of novelty (semi-independent travel). On the other hand, the tourists with high degree of novelty seeking comparatively tend to show preference for the travel journey with novel attributes or just a product with high degree of novelty (semi-independent travel). Here what calls our attention is that, when the tourism product is with high degree of novelty (semi-independent travel) and is combined with the travel journey with novel attributes at the same time, it may cause information overload for consumers thus raise their learning cost instead. This even causes consumers to produce negative or confused attitude when evaluating the product. Hence, for the (tourism product) suppliers who want to release new products to the market, I suggest that product design should be emphasize on adding appropriate novelty. For example, semi-independent travel attracts consumers with both high and low degree of novelty seeking; tour package with novel attributes is also safe for tourists. What we should be aware of is that too much novel information increases consumer’s learning cost, and once it causes consumer’s information to overload, it may cause negative effect instead.

[pt] A informação é considerada atualmente um recurso essencial para a sobrevivência e o desenvolvimento das organizações. O advento de novas tecnologias de informação e comunicação possibilitou ofertar uma enorme quantidade de dados para uso de diretores, gerentes e gestores de negócios, em uma escala jamais imaginada há poucas décadas atrás. No entanto, o uso efetivo da informação envolve uma série de aspectos que não dependem apenas da quantidade e da tecnologia, mas de fatores que permitam capitalizar o seu valor, melhorando a qualidade das decisões nas organizações. Este trabalho busca conhecer melhor a relação existente entre os processos organizacionais de gestão da informação e sua influência no processo decisório de uma grande organização pública brasileira, a Previdência Social. Para tal, foram utilizados conceitos teóricos sobre gestão da informação disseminados por Marchand, Davenport e Checkland. A pesquisa foi realizada através de análise documental, observação participante e entrevistas semi-estruturadas, utilizadas para coletar as percepções e o comportamento relativo à tomada de decisão de diversos gestores das três instituições componentes da organização. A análise dos resultados revela aspectos que poderão contribuir para um melhor entendimento dos problemas de negócio e de informação vividos pela organização estudada, e aponta alternativas que tornem mais efetivos seus processos de informação, visando o aumento da qualidade dos serviços prestados à população brasileira. / [en] Information is nowadays considered an essential resource for the survival and development of organizations. The advent of new information and communication technologies made possible to offer an enormous amount of data for directors, managers and business executives´ use in a scale never imagined a few decades ago. Nevertheless, the effective use of information cover several aspects which not only depend on quantity or technology, but also on factors that allow to capitalize its value, improving decision quality in the organizations. This work searches to know better the existing relation between the organizational processes of information management and its influence on decision-making of a large Brazilian public organization, the Social Security. In this way, theoretical concepts about information management spread by Marchand, Davenport and Checkland were used. The research was executed through documental analysis, participant observation and semi-structured interviews, all used to collect perceptions and behavior related to decision-making of several executives of the three institutions that make up the organization. The analysis of the results reveals aspects which may bring about a better understanding of business and information problems experienced by the studied organization, as well as pointing out alternatives to turn its information processes more effective, in order to aim at quality services increase granted to Brazilian population.

This study set off in a notion, rather than insight; there seems to be a lot of talk about how innovation should thrive and how the environment should be scanned, but not so much about the relationship in between. While the usefulness of sharing information about the environment is seldom questioned, how the information sharing comes to play is as seldom a topic for debate. This sparked our curiosity and to explore the phenomena deeper we conducted interviews with nine out of the ten co-workers within the unit for Research & Innovation at LFV. The result indicates that while environmental scanning was believed to be an important part of their work, they had no strategic guidelines on how it should be exerted and it was viewed to be more of a passive part in their practical work. Furthermore, their work situation was highly individualized and autonomous, which made them very motivated to scan the environment, but also caused a certain discrepancy in how they perceived it. This combination of disparate perspectives, high motivation and lack of unanimity resulted in a rather narrow monitoring of the environment and an imbalance between the interest and the actual use of information. While information was greatly sought after by everyone, the information shared was not perceived as meaningful in the same extent. Some co-workers meant this induced an overload of information and therefore became more restrictive in their information sharing, but others became frustrated that the information they shared never seemed to be used and thus shared even more as a response. Hence, the effect was not only self-fulfilling and reflexive, but also inhibited the environmental scanning from becoming a significant element in the innovation process. / Denna studie tog avstamp i en uppfattning, snarare än en insikt; det verkar talas gott om hur innovation ska frodas och hur omvärlden ska bevakas, men desto mindre om relationen däremellan. Medan nyttan med att dela information om omvärlden sällan blir ifrågasatt, verkar det lika sällan fokuseras på hur den informationsdelningen går till i praktiken. Detta väckte vår nyfikenhet och för att utforska fenomenet djupare utförde vi intervjuer med nio av de tio medarbetarna på enheten för Forskning & Innovation på LFV. Resultatet indikerar att omvärldsbevakning ansågs vara en viktig del av verksamheten, men att det fanns få strategiska riktlinjer om hur det ska utföras och att det var en mer passiv del av arbetet. Vidare var arbetssituationen högst individuell och autonom, vilket gjorde dem mycket motiverade att scanna sin omgivning, men också skapade en viss diskrepans i hur de uppfattade den. Denna kombination av olikartade perspektiv, hög motivation och brist på samstämmighet resulterade i en något snäv bevakning av omvärlden och en obalans mellan intresset och användningen av information. Samtidigt som information var mycket eftertraktat så blev inte informationen som delades uppfattad som meningsfull i samma utsträckning. Vissa medarbetare upplevde att detta genererade ett överflöd av information och blev därför mer restriktiva i sin informationsdelning, men andra blev frustrerade över hur informationen de delade aldrig verkade komma till användning och reagerade med att dela ännu mer som följd. Därav blev effekten inte bara självuppfyllande och reflexiv, utan hämmade också omvärldsbevakningen från att bli ett betydelsefullt element i innovationsprocessen.
