LuxUI: Repurposing ambient light sensor for contact-based explicit interaction on smartwatch
Hyoseok Yoon, Min-Sung Park, Se-Ho Park, Kyung-Taek Lee · 2015
In this paper, we propose a novel LuxUI based on an ambient light sensor as an alternative input method for smartwatches. We present a concept of LuxUI with design and implementation details of LuxUI interactions and events followed by possible applications and discussion issues. The proposed LuxUI is simple in design yet effective which works well for 200 ms interval interaction with a modest battery usage. For contact-based explicit interaction on smartwatches, the proposed LuxUI can be used as an alternative UI for otherwise expressivity-limited smartwatches.
