Most of the interactivity, however, is limited to the size of the display, introducing issues such as screen occlusion and limited information density. We introduce Wristband.io, a smartwatch with an extended interaction space along the wristband, enabling (i) back-of-band interaction using a touchpad, (ii) a low resolution ambient watchband display for off-screen notification, and (iii) tangible buttons for quick, eyes-free input. Insights gained through a study show that back-of-band input increases accuracy and task completion rates for smaller on-screen targets. We probe the design space of Wristband.io with three applications. date: 2017-05-06 publisher: ACM publishing official_url: http://dx.doi.org/10.1145/3027063.3053132 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1293118 doi: 10.1145/3027063.3053132 lyricists_name: Brudy, Frederik lyricists_id: FMBRU24 actors_name: Brudy, Frederik actors_id: FMBRU24 actors_role: owner full_text_status: public publication: CHI EA '17 Proceedings of the 2017 CHI Conference Extended Abstracts on Human Factors in Computing Systems place_of_pub: New York, NY, USA pagerange: 2025-2033 event_title: CHI Conference Extended Abstracts on Human Factors in Computing Systems event_location: Denver, Colorado, USA event_dates: 06 May 2017 - 11 May 2017 institution: CHI Conference Extended Abstracts on Human Factors in Computing Systems book_title: Proceedings of the 2017 CHI Conference Extended Abstracts on Human Factors in Computing Systems citation: Saviot, L; Brudy, F; Houben, S; (2017) WRISTBAND.IO: Expanding Input and Output Spaces of a Smartwatch.
