Application of Virtual Reality Technology in Online Fashion Store Development

Clothes fitting simulation is of great importance in assisting online fashion shopping. Recently, human mannequin and clothes simulations have improved to the point that they can generate realistic animation of clothes in real-time. However, under the constraints of online technologies, e.g. server calculation and download speed, this function is only available with larger online retailers. With the consideration of a low cost system installation and limited Internet download speeds, an experimental online toolkit development was undertaken. It consisted of creating and adjusting the digital human model, digitalising clothes data and virtually fitting clothes. Finally, the whole process was integrated into an online fashion shop.

Impact of Multi-sensory On-Bicycle Rider Assistance Devices on Rider Concentration and Safety

This study evaluated the impact of multi-sensory information cues from on-bicycle rider information assistance devices (OBRAD) on hazard perception performance. Experiments tested the impact of distraction from different combinations of visual, auditory and tactile sensory aids on the subject’s ability to maintain peddling frequency while conducting eight different tasks. The results indicate that the integrated use of different sensory cues (e.g., text, audible alerts and vibration) can decrease cognitive loading, with each sensory combination, particularly those involving tactile stimulation, having different levels of effect. Tactile sensory aids helped reduce the degree of rider distraction, thus helping maintain a high sensitivity to danger (hit rate mean: 0.34). Cycling performance was further improved through combining tactile stimuli with auditory cues for assistance in the secondary task. The implications of these findings and the need to integrate and manage complex OBRAD information systems are discussed.

The Impact of Media and Background Color on Handwriting

Handwriting is an important issue in Taiwan’s school system, and it remains to be determined if tablet computers are a suitable medium for the development of good handwriting. The primary purpose of this study is to determine whether visual and tactile instructional strategies can be used to help students improve their handwriting performance. The study recruited 31 6th grade elementary school students to hand write a short phrase on backgrounds of various colors (white, red, yellow, green and blue), both on pen and on tablet computer. Finally, a questionnaire was administered to determine emotional associations with the various background colors. Results showed that media type does have an impact on handwriting performance, with familiar media (paper) providing better results. Descriptive statistics indicate that using a red background provided the best subjective and objective performance, and consistently produced characters of better proportional size. Red was also found to have an emotional association with excitement and triggered positive emotions among the students.

Designing Copresent Cycling Experience

There has been much UbiComp research into motivating people to live more active and healthy lifestyle with sports. The idea behind these approaches is centered on social and peer effects in enhancing exercise adherence. While research of this kind has been prolific, there has very little work been done to identify factors that embody comfortable and informed accompanied exercise experience. This paper takes an increasingly attractive cycling theme as a testbed and proposes an unobtrusive and intuitive interface arrangement based on light. It can create a sense of being together with each other for distant apart cyclists. The initial results yield a good level of comprehension and motivation towards the use of the interface. The hope is that the elicited recommendations can guide the design of UbiComp technologies for social motivational physical exercises.

Are human faces more attractive with glasses

This article investigates whether a glasses frame, which is symmetrically designed, can be used as an accessory to enhance an individuals facial attractiveness and the affective responses. We carry out a series of experiments using 16 prototypical glasses frame, each of which consists of different combinations of design features. The frames are fitted on one male and one female faces selected from the facial portraits of 200 university students. The participants rate the faces with and without wearing the glasses frames with the 7-point Likert scales on the included perceptual measures. The results show that wearing the glasses frames does generally improve facial symmetry. However, the facial attractiveness is not enhanced accordingly. Some designs such as the glasses frames with smaller rims have less impact on facial attractiveness than those with larger rims. To conclude, artificially improving the facial attractiveness requires more than just an enhancement of facial symmetry.

Using on-Bicycle Rider Assistant Device While Cycling: A Hazard Perception Assessment

Technologies have been developed to assist the cyclist for precise training exercise such as monitoring their body and bicycle state. Due to the limited position placing on-bicycle rider assistant device and riding posture, it enlarges the essential view range of the chance the cyclist distracted from the road. The risks using the system have been evaluated through an interactive video-based hazard perception/reaction test in which response times were measured. 5 participants, 3 male and 2 female participated a 2-phase section including 7 traffic scenes in a 5 minutes cycling exercise with and without using on-bicycle rider assistant device. As the results, average reaction times tended to increase 0.33 seconds and average mis-maintained pushing cadence time was 31.4 seconds when cycling with the device assistance. It is concluded that cadence control assisted by the device can interfere the efficiency of hazard perception, an important safety factor of cycling.
