We discuss the design of an e-textile shirt with an interactive Lumalive display featuring a touch-controlled image browser. To determine where to place touch sensors, we investigated which areas of the Lumalive shirt users would be comfortable touching or being touched. We did so by measuring how often participants would opt out of touches. Results show significant differences in opt-outs between touch zones on the front of the shirt. For both touchers and touchees, opt-outs occurred mostly in the upper chest touch zone. We also found significant differences in comfort ratings between touch zones on the front as well as on the back of the shirt. On the front, the upper chest and lower abdominal zones were the least comfortable touch zones. We found no gender effects on overall comfort ratings, suggesting the upper chest area was equally uncomfortable to males as it was to females. Interestingly, touching some areas rated as most uncomfortable produced a significantly greater calming effect on heart rate. Findings suggest participants were less comfortable with touches on the upper chest, the lower abdomen, and the lower back. We conclude that the most appropriate areas for touch sensors on a shirt are on the arms and shoulders, as well as on the upper back. Based on these findings, we created an interactive shirt for a proximity-based game of tag using Lumalive e-textile displays. This custom shirt features touch sensors located on the shoulder and lower arm regions of the shirt. / Thesis (Master, Computing) -- Queen's University, 2011-08-29 16:27:36.37
