This article investigates whether a glasses frame, which is symmetrically designed, can be used as an accessory to enhance an individual's 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.
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.
