Designing a Digital Tool for Inclusive Communication in Recruitment : Developing a User Centred Web Application to Promote Learning

Wall, Hanna January 2024 (has links)
Having diversity at companies comes with many benefits, such as outperforming other companies due to having more perspectives. In Sweden's tech industry, diversity is lacking in many ways. There are several reasons, but one contributing factor is that we are biased. Bias is the tendency to prefer or dislike something without a valid reason. It is often unconscious and can be found in job ads. Having biases in job ads can make competent people avoid applying for jobs for which they are qualified. The wording in job ads plays a huge difference in getting diverse applicants.  This master’s thesis, conducted in the spring of 2024 in collaboration with Tromb focuses on developing a proposition of a new digital prototype for the NoBias tool. The tool aims to promote inclusive communication by using AI and machine learning, and the primary users are people working within recruitment. The NoBias project wants to contribute to increasing diversity in the Swedish tech industry. The current NoBias tool is a website where text can be analysed to identify biased words or phrases based on age, gender, and ethnicity. Then, the tool suggests a new text that is more inclusive, which the user can use. This master’s thesis centres around creating an interface that analyses the text and promotes learning of biases to make the user more aware of biases. The interface should be norm- creative, inclusive and easy to use.  To create the proposition of the interface, the design thinking process was used as the framework, containing the phases: empathise, define, ideate, prototype and test. Users were involved in all the process phases to get new perspectives and feedback regularly. The usability framework was applied to create the user experience by conducting user tests throughout the design process. To create an accessible interface, the WCAG guidelines were applied.  The project resulted in a digital interface consisting of a dashboard with an overview of the learning progress and the effect of using the tool to motivate the user to learn. On the dashboard, an overview of the documents is provided, and the user can either create a new document or upload a document that can be analysed. The text gets analysed in the document view, where words or phrases that contain bias get highlighted in the document, and a box with more information about the bias appears. The box contains information about why using that word or phrase is problematic and the benefit of using a more inclusive formulation. The user gets to create a better alternative with guidance from the prototype to promote learning of biases.  To ensure the robustness and inclusivity of the NoBias tool, I strongly recommend conducting extensive user testing on the final prototype. This user testing should involve a diverse range of users to gather a broad perspective. Additionally, I emphasise the importance of adhering to the WCAG accessibility guidelines during the development of the prototype to ensure that the NoBias tool is inclusive and can be used by everyone. / Att ha mångfald inom företag kommer med många fördelar, såsom att prestera bättre än andra företag på grund av att de har fler perspektiv. I Sveriges tech-industri saknas mångfald på många plan. Det finns flera anledningar till det, men en bidragande faktor är att vi är bias. Bias är tendensen att föredra eller ogilla något utan en giltig anledning. Det är ofta omedvetet och kan finnas i jobbannonser. Att ha bias i jobbannonser kan göra att kompetenta personer undviker att ansöka till jobb de är kvalificerade till. Formuleringar i jobbannonser spelar stor roll för att få bredd bland sökande.  Denna masteruppsats, genomförd våren 2024 i samarbete med Tromb, fokuserar på att utveckla en ny digital prototyp för NoBias-verktyget. Verktyget syftar till att främja inkluderande kommunikation genom att använda AI och maskininlärning, och de primära användarna är personer som arbetar inom rekrytering. NoBias-projektet vill bidra till att öka mångfalden i den svenska tech-industrin. Det nuvarande NoBias-verktyget är en webbsida där text kan analyseras för att identifiera ord eller fraser som är bias baserat på ålder, kön och etnicitet. Sedan föreslår verktyget en ny text som är mer inkluderande, som användaren kan använda. Denna masteruppsats fokuserar på att skapa ett nytt gränssnitt som analyserar texten och främjar lärande om bias för att göra användaren mer medveten om bias. Gränssnittet ska vara normkreativt, inkluderande och lätt att använda.  För att skapa förslaget till gränssnittet användes design thinking-processen som ramverk, innehållande faserna: empatisera, definiera, idégenerera, prototypa och testa. Användare var involverade i alla faser för att få nya perspektiv och regelbunden feedback. Användbarhetsramverket tillämpades för att skapa användarupplevelsen genom att genomföra användartester under hela designprocessen. För att skapa ett tillgängligt gränssnitt följdes WCAG-riktlinjerna.  Projektet resulterade i ett digitalt gränssnitt bestående av en hemskärm med en översikt över utvecklingen av lärande och effekten av att använda verktyget för att motivera användaren att vilja lära. På hemskärmen ges en översikt över dokumenten, och användaren kan antingen skapa ett nytt dokument eller ladda upp ett dokument som kan analyseras. Texten analyseras i dokumentvyn, där ord eller fraser som innehåller bias markeras i dokumentet, och en ruta med mer information dyker upp. Rutan innehåller information om varför det är problematiskt att använda ordet eller frasen och fördelen med att använda en mer inkluderande formulering. Användaren får skapa ett bättre alternativ med vägledning från prototypen för att främja lärande om bias.  För att säkerställa kvalitén och inkluderingen av NoBias-verktyget rekommenderar jag starkt att genomföra omfattande användartester av den slutliga prototypen. Dessa användartester bör involvera mångfald av användare för att få ett brett perspektiv. Jag föreslår att följa WCAG-riktlinjerna under utvecklingen av prototypen för att säkerställa att NoBias-verktyget är inkluderande och kan användas av alla.

The development of a reference database of health information resources to facilitate informed lifestyle choice

Cottrell, Genevieve Lee 30 June 2008 (has links)
This study investigates, within the current health care situation, the interrelationship of the user, resources and tool in the design of a prototype WELLNESS database-driven web site. A shift has taken place in health care, in which the base of conventional medicine has broadened to integrate other systems, practices and worldviews. These include complementary and alternative medicine, health promotion, disease prevention and wellness. Emphasis is placed on the need to take personal responsibility for one's own health and wellness. The global burden of chronic disease, reaching epidemic proportions, is increasingly linked to risk factors resulting from personal lifestyle choices. The growing evidence of the user's need to make personal, informed, lifestyle choices and their reliance on the Web for health information, required investigation. WELLNESS, a specific orientation to health and wellness, formed the framework within which the user and resources were defined and the tool designed. The user was profiled as the WELLNESS health information seeker, hereby contributing significantly to an understanding of the user in this new context. The user profile informed the establishment of resource selection criteria and tool design. The identification of WELLNESS content selection criteria, within a five-dimensional model, was required to ensure quality, relevant and credible resources. The tool is comprised of the WELLNESS thesaurus and WELLNESS database-driven web site. The WELLNESS thesaurus was constructed based on a combination of relevant thesauri. It will be used as an indexing tool. An investigation of existing health information web sites highlighted the importance of designing a specific WELLNESS database-driven web site. A database host was identified against which the original study's conceptual schema was assessed. A low-fidelity prototype web site was designed as the interface between the WELLNESS health information seeker and the database of WELLNESS health information resources. This study has epidemiological, philosophical, epistemological, sociological and psychological relevance. The provision of access to WELLNESS health information resources, made available in the WELLNESS database-driven web site, for personal, informed lifestyle choice by the WELLNESS health information seeker could potentially contribute to the reduction of the global burden of chronic disease. / Information Science / D.Litt. et Phil.

Dual-method usability evaluation of e-commerce websites : in quest of better user experience

Moczarny, Izabela Maria 10 1900 (has links)
E-commerce has increased substantially, as e-retailers engage with consumers online. Users require more than products and quality service; they also expect a good user experience. User experience is affected by branding, functionality, navigation, content, aesthetics and usability. This study investigates the attainment of better user experience on e-commerce websites. A dual-method usability evaluation approach – usability testing with end-users and heuristic evaluation by experts – was employed to obtain a holistic picture of how usability aspects support or hinder the user experience. Usability testing provided insights into detailed interface issues and the type of content and journey that users prefer when making a purchasing decision, while heuristic evaluation was mainly directed at overall user interface and interaction factors. In a complementary way, each method identified a high number of usability problems. Key findings are summarized, and design guidelines are identified that can facilitate the development of e-commerce websites to promote user experience. / E-handel het aansienlik toegeneem, soos e-kleinhandelaars by verbruikers aanlyn betrokke raak.

Processus d'innovation centré sur l'utilisateur : identification des besoins et interprétation des données issues de l'integration de l'utilisateur dans le processus de co-conception / User-centred innovation process : needs identification and data interpretation coming from the user's integration in the design process

Skiba, Nathalie 03 April 2014 (has links)
Jamais nos modes de vie et les produits qui nous entourent n'ont évolué aussi rapidement. Cette évolution est un facteur nouveau à prendre en compte dans le développement de produits pour s'assurer de leur appropriation par les utilisateurs. C'est ainsi que les approches de conception s'orientent petit à petit vers l'intégration des usages. L'approche Living Lab est axée autour de quatre principes : le réalisme de la situation d'usage étudiée ; la continuité de la collaboration avec les utilisateurs ; la collecte de données d'usage spontanées ; l'augmentation de la capacité des utilisateurs à influencer le développement du produit. Ces principes facilitent le passage de la conception centrée-utilisateurs vers la conception centrée-usages, mais sont difficiles à réaliser concrètement. Pour accompagner et inspirer les concepteurs, nous proposons une méthode de pilotage de projet Living Lab composée de dix-huit opérations visant chacune l'atteinte d'un de ces principes. La méthode proposée est représentée sous forme de diagrammes NIAM-ORM, facilement compréhensibles car proche du langage naturel binaire. Deux projets urbains et deux projets industriels ont permis de tester notre méthode. La pertinence des opérations sur l'atteinte des principes est évaluée par le biais des réseaux bayésiens : selon les résultats obtenus, les opérations sont validées, ajustées ou reformulées puis ré-implémentées dans le modèle NIAM-ORM / Our way of life and the products that surround us have never evolved so quickly. This evolution is a new factor to take into account in the product development to ensure the product appropriation by the users. For that reason the design approaches try to integrate usages. The Living Lab approach is organised around four principles: the realism of the studied situation; the continuity in the collaboration with the users; the collection of spontaneous usage data; the empowerment of users in the design process. These principles facilitate the path from "user-centred design" to "usage-centred design" but are difficult to realise practically. To guide and inspire the designers we propose a Living Lab project method made of eighteen operations; each operation is supposed to reach one of the four principles. The proposed method is represented with NIAM-ORM diagrams which are easily understandable because of its similarity with natural language. We tested our method on two urban projects and two industrial projects. The relevance of the tested operations on the principle realisation is evaluated according to bayesian networks: depending on the results the operations are validated, adjusted or rephrased and implemented again in the NIAM-ORM model

Développement de connaissances cliniques pour l’adaptation d’une technologie d’assistance cognitive pour soutenir des personnes ayant un traumatisme crânio-cérébral grave pendant la préparation de repas à domicile

Gagnon-Roy, Mireille 06 1900 (has links)
Reconnu comme l’une des principales causes d’invalidité, le traumatisme crânio-cérébral (TCC) est une condition chronique pouvant occasionner des déficits physiques, cognitifs, émotionnels et comportementaux. Ces déficits interfèrent avec la capacité de la personne à s’engager dans ses activités quotidiennes, incluant des activités complexes comme la préparation de repas. Afin de soutenir cette population lors de la préparation de repas, une technologie d’assistance à la cognition (TAC) nommée Cognitive Orthosis for coOKing (COOK) a été développée en partenariat avec une résidence alternative pour des personnes ayant des incapacités graves à la suite d’un TCC. Suivant l’installation de COOK, trois résidents ont été en mesure de préparer des repas de façon sécuritaire et autonome. Toutefois, rien n’est connu sur la façon avec laquelle COOK pourrait répondre aux besoins des personnes ayant eu un TCC et vivant dans la communauté, ni comment cette technologie pourrait offrir de l’assistance personnalisée, minimale et contextualisée pour soutenir cette population. Cette thèse vise donc à développer des connaissances pour soutenir le développement d’une version bonifiée de COOK qui correspondrait aux besoins variés de ces utilisateurs, en répondant à trois objectifs : 1) définir les besoins d’assistance verbale des personnes ayant eu un TCC modéré à grave afin d’améliorer les capacités de personnalisation de COOK; 2) évaluer son utilisabilité et expérience utilisateur en laboratoire et en milieu réel; et 3) identifier les facilitateurs et obstacles pouvant influencer l’implantation de COOK auprès de personnes ayant eu un TCC et vivant dans la communauté. Suivant une démarche de conception centrée sur l’utilisateur, quatre études ont été réalisées : (1) une étude mixte avec transformation des données et analyse d’enregistrements vidéo pour documenter l’assistance verbale offerte à 45 participants ayant un TCC lors de la préparation d’un repas; (2) une étude d’utilisabilité mixte pendant laquelle 10 participants ayant un TCC ont testé COOK en laboratoire; (3) une étude mixte à sujet unique pour évaluer l’utilisabilité de COOK au domicile d’une personne ayant eu un TCC grave; et (4) une étude qualitative descriptive impliquant des personnes ayant eu un TCC, des personnes proches aidantes et des intervenants, pour explorer leurs perceptions quant aux facilitateurs et obstacles à l’implantation de COOK dans leur milieu respectif. La première étude a permis d’identifier neuf types d’assistance cognitive et un type d’assistance motivationnelle, et de documenter les difficultés pour lesquelles les ergothérapeutes offraient de l’assistance. Des enjeux d’utilisabilité ont ensuite été documentés pendant les essais en laboratoire (étude 2) et en milieu réel (étude 3), particulièrement au niveau du système de sécurité autonome. Plusieurs besoins de bonifications technologiques ont aussi été identifiés par les participants (études 2, 3 et 4). Enfin, la quatrième étude a identifié divers facilitateurs (p.ex. les fonctionnalités disponibles dans COOK) et obstacles (p.ex. la logistique entourant l’installation, l’apprentissage et le soutien) à l’implantation de TAC comme COOK pour soutenir les personnes vivant dans la communauté avec un TCC grave. Ultimement, ces connaissances cliniques pourront soutenir le développement continu et l’implantation de TAC comme COOK pour qu’elles répondent aux besoins d’une plus grande population. / Defined as one of the main causes of disability, traumatic brain injury (TBI) is a chronic condition that can cause physical, cognitive, emotional, and behavioral deficits. These deficits may interfere with the person's ability to engage in daily activities, including complex activities such as meal preparation. To support this population during meal preparation, an assistive technology for cognition (ATC) called Cognitive Orthosis for coOKing (COOK) was recently developed in collaboration with an alternative residence for people with severe TBI. Following the installation of COOK, three residents were able to prepare meals safely and independently within their home. However, little is known about how COOK could meet the needs of people with TBI living in the community, or how it could provide personalized, minimal and contextualised assistance to support this population. This thesis aimed to develop a knowledge base to support the development of an improved version of COOK that would meet the varied needs of this new population, by meeting three objectives: 1) define the verbal assistance needs of people with moderate to severe TBI to enhance COOK's customization possibilities; 2) evaluate the usability and user experience of COOK in a laboratory setting and in a real-world environment; and 3) identify the facilitators and obstacles that may influence the implementation of COOK within the homes of people with TBI and in clinical settings. Integrated in a user-centered design process, four studies were conducted: (1) a study using conversion mixed design and video data analysis to document the verbal assistance provided to 45 participants with TBI during a meal preparation task; (2) a usability mixed-methods study during which 10 participants with TBI tested COOK in a laboratory setting; (3) a mixed-methods single-case study to assess the usability of COOK with a man with severe TBI living in the community; and (4) a qualitative descriptive study involving people with TBI, caregivers and healthcare professionals, to explore their perceptions of the facilitators and obstacles to the potential implementation of COOK in their respective settings. The first study identified nine types of cognitive assistance and one type of motivational assistance that were provided by occupational therapists to support people with TBI, and documented the difficulties for which these assistances were provided. Several usability issues were also documented when testing COOK in a laboratory setting (study 2) and in a real-world environment (study 3), particularly with the self-monitoring security system. Modification needs were also identified by the participants (studies 2, 3, and 4) to improve COOK. Finally, the fourth study highlighted many facilitators (e.g., the functionalities available in COOK) and obstacles (e.g., the logistics surrounding installation, learning and support of COOK) to consider before implementing ATCs like COOK. Ultimately, this knowledge base will support the continued development and the implementations of ATCs such as COOK to meets the needs of a larger population.

Enhancing User Satisfaction Through Micro-interactions: A Qualitative Study of Usability on Spotify

Hongjian, Li, Yujie, Zhou January 2024 (has links)
This study investigates the impact of micro-interactions on user satisfaction within music applications, specifically examining the usability differences between simpler and more complex interactions. The research employs semi-structured interviews to assess user satisfaction with two different levels of micro-interaction complexity. The goal is to derive actionable insights for optimising user-centred design in digital music streaming platforms, ultimately enhancing user satisfaction. The semi-structured interview method is chosen for this study, with the assistance of A/B testing designed by the researchers to gain realistic and informative qualitative data. To analyse a large amount of qualitative data, thematic analysis is utilised as the analytic method. The results reveal a clear preference for simple micro-interactions. Participants found these interactions required fewer steps, were more intuitive, and demanded minimal cognitive effort, thereby avoiding information and feature overload. In contrast, complex micro-interactions often led to confusion and frustration due to unnecessary complexity and unclear iconography. Moreover, participants expressed a need for personalised and voice-activated interactions to enhance usability and accessibility in diverse contexts. These findings underscore the importance of designing micro-interactions that align with users' mental models and preferences. By prioritising simplicity, intuitiveness, and personalization, music streaming services can significantly improve user satisfaction and engagement.
