Interruption Methods for Speech Interaction


The last chapter examined the design of an interruption handling for wearable user interfaces operated with gestures using a data glove device. This chapter presents a second user study conducted to investigate the properties of speech interaction to coordinate interruptions. Compared to glove-based gesture interaction, speech interaction offers real hands-free operation without even sporadically occupying a user’s hand during interaction. To relate findings and to make them comparable to previous findings for gesture interaction, the conducted experiment was closely related in its experiment setup to the previously presented experiment in chapter 8.
