Artificial grapheme-color synesthesia for wearable task support

This paper presents the benefits of generating an artificial visual synesthesia through a wearable computer. Following a short introduction to remind the need for seamless human-wearable computer interactions, this paper makes the case for drawing upon synesthesia, a combination of the senses naturally occurring in a small portion of the population, to augment everyday entities and more precisely to enrich written graphemes. We present the rationale behind our research and summarize the functionality, architecture and implementation of our current prototype. Preliminary results suggest that this kind of artificial synesthesia improves short term memory recall and visual information search times.
