We present results of a user study with a prototype of an interactive speech-enabled car owner's user manual assistant. Its purpose is to help the driver learn about various car features and related procedures. The study focused on two scenarios -when parked and while driving. We also used the Leap Motion gesture recognizer as an alternative to buttons. During the experiment we collected both objective driving data and subjective feedback. Results indicate that the users preferred the electronic user manual to the paper form, although they proposed numerous improvements. One particular concern was discoverability of content. The acceptance of Leap Motion gestures was low when driving, possibly impacted by short time allowed for practicing. Driver's distraction caused by interacting with the multimodal user manual was similar to that of receiving and reading text messages.
In this paper we introduce a new UI paradigm that mimics radio broadcast along with a prototype called Radio One. The approach aims to present useful information from multiple domains to mobile users (e.g. drivers on the go or cell phone users). The information is served in an entertaining manner in a mostly passive style-without the user having to ask for it-as in real radio broadcast. The content is generated on the fly by a machine and integrates a mix of personal (calendar, emails) and publicly available but customized information (news, weather, POIs). Most of the spoken audio output is machine synthesized. The implemented prototype permits passive listening as well as interaction using voice commands or buttons. Initial feedback gathered while testing the prototype while driving indicates good acceptance of the system and relatively low distraction levels.
