Unconstrained Pedestrian Navigation based on Vibro-tactile Feedback around the Wristband of a Smartwatch.

We present a bearing-based pedestrian navigation approach that utilizes vibro-tactile feedback around the user's wrist to convey information about the general direction of a target. Unlike traditional navigation, no route is pre-defined so that users can freely explore the surrounding. Our solution can be worn as a wristband for smartwatches or as a standalone device. We describe a mobile prototype with four tactors and show its feasibility in a preliminary navigation study.
