    Semi-aural Interfaces: Investigating Voice-controlled Aural Flows
    (Oxford, 2016-11) Ghahari, Romisa Rohani; George-Palilonis, Jennifer; Gahangir, Hossain; Kaser, Lindsay; Bolchini, Davide; Department of Human-Centered Computing, School of Informatics and Computing
    To support mobile, eyes-free web browsing, users can listen to ‘playlists’ of web content— aural flows . Interacting with aural flows, however, requires users to select interface buttons, tethering visual attention to the mobile device even when it is unsafe (e.g. while walking). This research extends the interaction with aural flows through simulated voice commands as a way to reduce visual interaction. This paper presents the findings of a study with 20 participants who browsed aural flows either through a visual interface only or by augmenting it with voice commands. Results suggest that using voice commands reduced the time spent looking at the device by half but yielded similar system usability and cognitive effort ratings as using buttons. Overall, the low-cognitive effort engendered by aural flows, regardless of the interaction modality, allowed participants to do more non-instructed (e.g. looking at the surrounding environment) than instructed activities (e.g. focusing on the user interface).
