Abstract

<p>To provide the design guidelines for notification, which are recognized in the peripheral vision by information device users who perform intellectual works, we examined the effect of “motion” in terms of awareness and concentration. Twenty participants performed dual task including mental arithmetic task on the central main-display and awareness task on the peripheral sub-display, and were evaluated by psychological, behavioral indices and eye movement. In the awareness task, participants were presented motion stimuli that had seven kinds of motions: instant, fade-in, expansion, contraction, horizontal, vertical and blink. The results showed that motion of horizontal and expansion significantly caused superior awareness and conveyance of meaning. Furthermore, only horizontal and expansion were not collected less preference votes than the condition of no notification. The relation between performance of awareness task in peripheral visual field and mental arithmetic task in central visual field was a significant positive correlation, not a trade-off. All results considered, this study suggested the motion design for notification that would be better horizontal from the viewpoint of users' preference, and would be better expansion from the viewpoint of conveyance of meaning.</p>
