Prototype wireless push-to-talk glove

In-car speech user interfaces play an increasingly significant role in vehicles and they use push-to-talk (PTT) buttons to allow the user to signal voice activity. We explore the differences in usage of a fixed location PTT button and a wireless PTT glove which allows a less restrictive field of operation. Our pilot study indicates that reducing the restriction on the location of the PTT button may make using the PTT button more comfortable compared to a fixed-location PTT button. Further studies are needed to evaluate the impact of the PTT glove on driving performance.
