Design issues of head-up displays and driving simulators: a European perspective
No full textHead-Up Display (HUD) interfaces aim to improve the driver’s spatial awareness and response times (RTs). In this paper HUD designs enhancing the quality and increasing the quantity of information provided to the driver utilising the vehicle’s sensors are discussed. HUD interface elements are based on minimalist visual representations of real objects, which shorten the learning curve and offer a compact form of interactive guidance for motorway environments. This work discusses the challenges involved in the HUD design, introduces the visual components of the interface and presents the outcome of system evaluation. The paper finally outlines the occurring issues in designing driving simulators for this type of evaluations.<br/
Investigation of prototype full-windshield head-up display interface impact on users' driving patterns under adverse weather conditions
No full textContemporary Head-Down Display information portrayed by automotive infotainment devices, while useful, is often ignored by the driver due to field of view limitations associated with traditional instrumentation panels. The proposed interface, as applied in a full-windshield Head-Up Display system, aims to improve the driver's situational and spatial awareness by considering information as it becomes available from various sources such as VANETs, GPS and other vehicular sensors. Effectively the vehicle's windshield transforms to an augmented reality display area which allows the system to present crucial information related to collision avoidance guidance to the driver in typical or adverse driving conditions. Opting for a simplistic approach of interaction, the interface superimposed on the actual environment. This paper discusses the challenges involved in the HUD design, introduces the visual components of the interface and presents the outcome of a large scale evaluation of the system on a group of forty drivers

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Technology acceptance model for 3D virtual reality system in luxury brands online stores
Full text linkThis paper presents an evaluation of a 3D semi-immersive virtual reality (VR) system for online luxury product visualization and customization service. This paper's objective is to present the results of the survey-based analysis using a technology acceptance model with ease of use, usefulness, perceived experience value, and perceived presence as independent variables, in testing the attitudes toward the system. The impact of product customization and personalization features on the perceived experience value and the attitudes toward the system was also tested. The result shows that the perceived presence, usefulness, ease of use, and the perceived experience value have a significant positive effect on the attitudes toward the 3D VR semi-immersive system. The result also revealed that utilizing the advantage of 3D VR systems with regard to real-time manipulation of the product and the flexibility in customizing the 3D models' features in real time has elevated the attitudes toward the aforementioned emerging technology within this specific context
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Enhancing human responses through augmented reality head-up display in vehicular environment
No full textContemporary needs for constant provision of information and communication has crowded the modern vehicle's interior with a variety of instrumentation displays. This abundance of automotive infotainment devices can reduce significantly driver's decision making process and response times, leading to higher probability of collision, especially under adverse weather conditions. Typical dashboard instrumentation has proven inefficient to tackle such issues and Head-Up Display (HUD) interfaces deemed as an increasingly viable alternative by recent developments in automotive research and manufacturing. This paper presents our current work towards the development of a full-windshield HUD interface that could enhance human responses and provide time-dependant and only critical information for collisions avoidance. For the evaluation of the system we have developed a VR driving simulator that simulates traffic flow and typical accident scenarios in motorway environment. Finally the paper presents the evaluation results and future work that would improve the interaction between HUD interface and driver
Feasibility Study for a Scottish Medical Visualisation Network
Full text linkThe Feasibility Study was conducted for one year between 2007 and 2008. This report describes the scope of the study through persons and organisations contacted, presents the case studies undertaken, on-going development work and concludes with a strategic overview of the area coupled to recommendations for the future.Traditionally, the only means medical practitioners have had to view real three-dimensional structures of the human body have been in the form of patients and cadavers. Now, however, advances in 3D visualisation technologies are making it possible to view and interact with such structures without the need or reliance on the use of real people or body parts. The ability to take vast quantities of existing two-dimensional sectional data, and render it into realistic interactive three-dimensional images has the potential to affect profound changes in medicine in terms of teaching, learning and cognition.The Digital Design Studio, together with the Royal College of Surgeons of Edinburgh, envisage the need for a sustainable, long-term network that will identify the key areas in future practice-based research in which 3D visualisation and interaction can support medical learning and teaching, surgical planning and rehearsal. Such a network of clinical practitioners, academics and visualisation experts with an interest in interactive real-time imaging, simulation and reusable learning objects, together with a natural constituency of medical schools and royal colleges, would provide Scotland with a profile in medical visualisation consistent with its existing international standing in medicine.The response to this Feasibility Study from the medical profession in general and to the formation of a dedicated Network has been overwhelming. There was an unreserved willingness and a spirit of cooperation on the part of all medical practitioners contacted to support the aims of the Study. The Study has resulted in the following achievements:The completion of five case studies in notoriously difficult fields each of which successfully demonstrated the rich potential of 3D visualisation to educate and inform where proper multi-disciplinary collaboration was developed between medical and visualisation experts. One of these, lung collapse, brought a new realisation that upturned conventional medical understanding and current teaching practice. The success of the case studies was instrumental in attracting additional funding from the Royal College of Surgeons, NHS Education Scotland, Ayr Hospital and Raigmore Hospital, Inverness
