“…Considering such a scenario places restrictions on the design of that display. As Pierce et al [17] point out in relation to VR hardware, requiring users to don elaborate mechanisms in order to interact with computer systems causes significant problems in and of itself. At the very least users can be reluctant to strap on bulky or restricting devices and this reticence is likely to be exacerbated in the mobile domain.…”

At first glance, multi-element forearm mounted vibrotactile displays would appear to have considerable potential as an output device for mobile computing. The devices are small, robust and discrete, and the body site both easily accessible and socially acceptable for such a purpose. However, due to the absence of a thorough account of vibrotactile perception, it is hard to determine their feasibility, or even what might form an appropriate arrangement of vibrating elements or tactors. We describe two studies intended to shed light on these issues. The first extends the localization literature relating to the forearm, and its results indicate that different spatial arrangements of tactors can result in substantially different levels of performance. The second study examines the influence of adjusting the size of the area of the skin experiencing a vibration with its perceived intensity. The results indicate a positive relationship between increased size and increased perceived intensity. Finally, the implications of these studies for the design of vibrotactile arrays are discussed.CR INTRODUCTIONIt has long been accepted that the skin, the largest organ in the body, has considerable potential as a conduit for information. Correspondingly, there is a substantial history of research investigating how it might be effectively utilized. This effort has led to the development of a wide variety of skin stimulation technologies, ranging from electrical to vibratory to pneumatic. Of these technologies, large scale vibrotactile displays, utilizing motor or transducer based vibrating elements, and considered either individually or in groups, have arguably been the most popular. The reasons for this are straightforward and easy to enumerate: they are simple to construct, small, cheap, robust, reliable, and consume modest amounts of power. Initial investigations with these displays during the 60's and 70's focused on sensory substitution, where the intention was that tactile stimuli could be used to represent otherwise absent visual or auditory cues to impaired users. To highlight one example from this era, rigorous empirical work on topics ranging from character recognition to the display of patterns representing the spatial aspects of visual scenes were conducted using various versions of TVSS [9], a system most typically incarnated as a 20 by 20 back mounted array of vibrating elements (or tactors). Beyond research with this laudable aim, more recent attention has begun to focus on the potential of vibrotactile stimuli in mobile computing scenarios. This is no doubt due to the dramatic rise of this domain during the last decade, in conjunction with a general recognition that non-visual cues have an important role to play in the interfaces to handheld or wearable computing devices [4], and, when compared to other types of haptic or tactile device, the practical suitability of vibrotactile displays to mobile environments.Tan [21] provides one of the earliest discussions of vibrotactile displays for mobile computing....

“…In another research project, ALICE [17], Salem et al took inspiration from Alice in Wonderland project [14] and created an augmented reality (AR) narrative with intelligent agents acting as characters who lead the user through virtual and real locations, moral choices and emotional states. ALICE is designed to provoke self-reflection on unconscious cultural issues such as logic and reasoning, self and ego, selfishness and selflessness.…”

Confucianism is commonly defined as ''... a system of philosophical, ethical and political thought based on the teachings of Confucius,'' which originated through the teachings of Confucius during the sixth-century BCE. It is a way of life or a philosophy of human nature that considers human relationships as the foundation of the society. Confucius teachings had highly influenced the development of several cultures in Asia, making Confucianism an intangible cultural heritage. In this paper, we are re-acquainting users with an intangible heritage that is part of their everyday, by developing a system that permits experiencing Confucius teachings virtually and interactively. The system can measure philosophical intent of the human and generate meaningful philosophical answers. It is also aimed for intergenerational sharing of Confucius heritage through a simple interactive process with the virtual sage making the experience enjoyable and entertaining. Previous research in natural language processing (NLP) mainly focused on the understanding and delivering of human natural language accurately. In this research, we explored how to apply NLP to model the knowledge and teachings of Confucius, through the natural conversation between human and computer. This virtual Confucius, a chat agent that generates outputs based on Confucius teachings, using a series of algorithms and techniques to improve the matching accuracy between user input and computer output, introduces a novel way of interacting with intangible cultures. Our user evaluation results revealed that there is a positive correlation between relevance and enjoyment, finding their experiences interacting with virtual Confucius very encouraging. Adults who participated in experiencing the virtual Confucius together with their children believed that this system has the potential to improve intergenerational interactions through shared play.

“…34 Conflicting this is the natural tendency for normal users not to turn their heads in the HMD; thought to be based on our repeated exposure to TVs and large movie screens where "head turning is counterproductive." 35 Pierce also reports that users may not realize that they can turn their heads while wearing an HMD, and thus, do not do so. In this case, measures of smaller head turning do not necessarily signify discomfort.…”

The use of virtual environments with head-mounted displays (HMDs) offers unique assets to the evaluation and therapy of clinical populations. However, research examining the effects of this technology on clinical populations is sparse. Understanding how wearers interact with the HMD is vital. Discomfort leads to altered use of the HMD that could confound performance measures; the very measures which might be used as tools for clinical decision making. The current study is a post-hoc analysis of the relationship between HMD use and HMD comfort. The analysis was conducted to examine contributing factors for a high incidence of simulator sickness observed in an HMD-based driving simulator. Pearson correlation analysis was used to evaluate objective and subjective measures of HMD performance and self-reported user comfort ratings. The results indicated weak correlations between these variables, indicating the complexity of quantifying user discomfort and HMD performance. Comparison of two case studies detailing user behavior in the virtual environment demonstrates that selected variables may not capture how individuals use the HMD. The validity and usefulness of the HMD-based virtual environments must be understood to fully reap the benefits of virtual reality (VR) in rehabilitation medicine. 591
