Visual Communication Console : Sharing Safety-Critical Information between Heavy Vehicles and Vulnerable Road Users

Gomli, Dastan, Lindström, Erik January 2019 (has links)
Background. Over the years, between 2013 and 2017, accidents between HeavyGoods Vehicles and Pedestrians have come to increase. Leading causes stem frominattentiveness and lack of communication between driver and pedestrians. Withthe advent of Autonomous vehicles, set to be able to reduce accidents, uncertainties in how communication and trust between humans and machines will be formed re-mains. Objectives. The research aim has been to understand the difficulties and problemssurrounding heavy vehicles, and the problems that today’s heavy vehicle operators faces, from which a technical solution that addressees the uncovered needs, is devel-oped. Methods. Design Research Methodology and MSPI Innovation Process has beenused in combination for acquiring and validating information around the problem.Shadowing sessions, unstructured interviews has been used for acquiring information.Literature reviews have been done to find academic validation in hypotheses statedthroughout the research. From the information gathered, iterative prototypes havebeen built. Results. From the needfinding that was conducted, safety around trucks was thefield on which the scope of the research was focused around. Due the larger size oftruck, decision-making through eye contact and intention determining is set to beharder when dealing with heavy vehicles, leading to an uncertainty around heavyvehicles residing with pedestrians in how to act around these. With the operatorsof these vehicles finding the unpredictable nature of pedestrians and cyclist in trafficto be troublesome and safety imposing, the research aim was set around addressing these needs. A communication console was developed, that is able to communi-cate safety-critical information between heavy vehicle operators and vulnerable road users, as means of reducing front collisions between said parts. Conclusions. The console has been developed through iterative prototyping andtesting, with design requirements being acquired through learnings and feedbackgathered from each iteration. The resulting communication console being presentedis able to share critical information being sought by pedestrians for decision-making,primarily that of eye contact and intentions of oncoming vehicles. The system servesas a proof of concept, that could through extensive traffic safety testing, help reducefront collisions between Heavy Goods Vehicles and Vulnerable Road Users, as well as, through further development, become the central communication console for au-tonomous vehicles to ensure partnership and intuitive communication between these and the surroundings.

Designing for Web Sustainability: The Potential of Nudges and Sustainable Web Design in Reducing the Environmental Footprint of Communication Platforms : Development and evaluation of a fictional communication platform with a sustainability-focused approach

Thiess, Anne, Andersson, Joella January 2023 (has links)
Digital communication through communication platforms has increased and changed significantly during the last decade and recently not least because of the corona pandemic, which has shifted many face-to-face activities to the internet (Obringer R. , et al., 2021). This paper firstly contains a quantitative survey study that investigates human behaviour and their experience on digital communication platforms with a focus on media transfer of photos and videos. Afterwards, the data sizes of various media after transfers through diverse communication platforms are explored in an experiment. This is followed by the development of a prototype in which sustainable design is implemented and aim to nudge the user to more sustainable-friendly digital behaviour relating data transfers of media and the settings of a communication platform. Finally, the prototype undergoes usability testing through which the user experience and positive environmental impact is evaluated. The findings reveal that the implementation of sustainability-focused nudges, features and design within a communication platform can lead users to more sustainable decisions in one or more areas of the platform and thus improve its environmental footprint.

創作交流平台經營模式與著作權議題之研究 / A Research on Business Models and Copyright Issues For the Creation Communication Platform

張文愷, Chang, Wen Kai Unknown Date (has links)
隨著網際網路興起,資訊的交流與傳遞產生了革命性的變化,同時也影響了許多產業既有的經營與交易模式,電子商務以及產品/服務數位化的概念開始大行其道。近年來,網際網路的即時性與互動性,更促成平台經營模式的興起,藉由打破傳統交易模式中單向的供應鏈形式,平台建立了多方使用者對資訊及產品/服務在供給與需求上的循環性,促成交易成本降低,進而創造更多新的商機。 以傳統出版業為例,受限於書籍在印刷出版時高額的固定成本,廠商通常只能向已具有市場規模的知名作家或經濟人進行作品出版的提案與邀約;而對於消費者來說,也僅能就市場提供的產品進行選擇。另一方面,對於許多有潛力但尚未被發掘的創作者而言,也因為缺乏能實際接觸市場的機會與管道而遭到埋沒,而對廠商來說,過高的搜尋成本與投資風險也形成了發掘這些新銳作家的障礙。 本研究試圖以平台策略與經營模式為基礎,探討創作交流平台對於傳統出版業以及其數位化過程中所產生的衝擊與影響,並試圖建立一套能有效促成創作者、使用者與廠商三方獲益的資訊交流平台;最後,針對創作在數位化過程中最容易遭遇到的著作權問題,本研究也將以平台經營管理的角度加以審視分析,並提出相關政策上之建議。因此,本研究之研究問題係總結為以下三點: 1.創作交流平台對於傳統出版業與出版數位化的影響與競合關係 2.創作交流平台經營模式與成功關鍵之分析 3.創作交流平台著作權法律相關政策與議題之探討 / As Internet became more and more popular, there was a revolutionary change about transportation of information, and it also deeply influenced many industries’ original operation and transaction models. For this reason, e-commercial and digitization of products and services started to prevail. In recent years, because of Internet’s instantaneity and interactivity, platform business models start to spring up. By breaking through the traditional one-way supply chain, platforms try to find the circulation between each type user’s supply and demand of products or services. Platforms model decrease the transaction cost and help many people find the new business. Take traditional publishing industry for example, for fear of the high fixed cost of books publishing; publishers only publish books by well-known authors or through agents with good reputation. For customers, they can only passively choose from the items supplied. Besides, many potentially brilliant authors may be neglected under this circumstance, because they lack channels to approach the market and audiences. Considering the searching cost and risk, it’s also difficult for publishers to discover these potential creators. This research will be based on platform strategies and business models, discussing the influence and transformation result from creation communication platforms during digitization process of traditional publishing industry. Furthermore, this research will try to build up a platform business model to make users (including creators, audiences and publisher) profit. At last, this research also covers the copyright issue about creation communication platform, and brings up some advices for platform policies. After all, this research will focus on three questions as below: 1.Influence and transformation result from creation communication platforms during digitization process of traditional publishing industry. 2.Analysis about creation communication platforms’ business models and key factors for making success. 3.Discussion of creation communication platforms’ copyright issues and related business policies.

Konfigurierbare Softwarekomponenten zur Unterstützung dynamischer Lern- und Arbeitsumgebungen für virtuelle Gemeinschaften

Roth, Alexander, Hampel, Thorsten January 2005 (has links)
Die Kontexte, in denen Mitglieder virtueller Gemeinschaften zusammen lernen und arbeiten, werden von einer Vielzahl von Faktoren beeinflusst: Während heutige Lernumgebungen oftmals mehrere didaktische Konzepte und ihre flexible Kombinierbarkeit (blended learning) berücksichtigen müssen, treten wechselnde Anforderungen an Arbeitsumgebungen virtueller Gemeinschaften häufig durch eine Steigerung des Sozialisierungsgrades und dem damit verbundenen Wunsch nach mehr Selbstadministration bzw. –regulation auf. Somit ist die Notwendigkeit zur Unterstützung dynamischer Kontexte zwar jeweils unterschiedlich begründet, führt aber bei der Umsetzung beider Systemklassen zu derselben konzeptionellen Herausforderung: Die technologische Infrastruktur muss möglichst reaktions- und anpassungsfähig bzgl. Kommunikation, Interaktion und Zusammenarbeit gestalten werden, um sowohl der individuellen als auch der kollektiven Entwicklungsdynamik ihrer Benutzer Rechnung zu tragen.
