Gestural interaction with freehands and while grasping an everyday object enables always-available input . To sense such gestures, minimal instrumentation of the user’s hand is desirable. However, choice effective but IMU layout remains challenging, due to complexity multi-factorial space that comprises diverse finger objects, grasps. We present SparseIMU , a rapid method for selecting inertial sensor-based layouts gesture recognition. Furthermore, we contribute computational tool guide designers optimal sensor placement. Our approach builds on extensive microgestures dataset collected dense network 17 measurement units (IMUs). performed series analyses, including evaluation entire combinatorial freehand (393 K layouts), quantified performance across different choices, revealing new detection opportunities IMUs. Finally, demonstrate versatility our four scenarios.
