“…Due to its higher sensitivity and wider sensing range, low-cost radar is increasingly replacing PIR sensors in smart lighting products that sense motion to turn on the light automatically, for example. In computing, recent research has focused on using radar for small finger motion recognition [32,61], augmented reality interactions [19] and musical applications [10,48], activity recognition [5] and human pose tracking through walls [1,72]. In the health domain, radar related sensing has been explored for monitoring glucose levels in blood samples non-invasively [37,52], breathing and heart rate monitoring [2], sleep sensing [44] and emotion tracking [71] in a smart home environment.…”

Research has explored miniature radar as a promising sensing technique for the recognition of gestures, objects, users' presence and activity. However, within Human-Computer Interaction (HCI), its use remains underexplored, in particular in Tangible User Interface (TUI). In this paper, we explore two research questions with radar as a platform for sensing tangible interaction with the counting, ordering, identification of objects and tracking the orientation, movement and distance of these objects. We detail the design space and practical use-cases for such interaction which allows us to identify a series of design patterns, beyond static interaction, which are continuous and dynamic. With a focus on planar objects, we report on a series of studies which demonstrate the suitability of this approach. This exploration is grounded in both a characterization of the radar sensing and our rigorous experiments which show that such sensing is accurate with minimal training. With these techniques, we envision both realistic and future applications and scenarios. The motivation for what we refer to as Solinteraction, is to demonstrate the potential for radar-based interaction with objects in HCI and TUI.
