Desktop at Fingertip is a proof-of-concept prototype system that approaches the desktop interaction paradigms of cursor control and text input through two-finger in-air micro-gestures. Our system is based on millimeter-wave radar sensing. We present "ThuMouse," a novel interaction paradigm aimed to create a gesture-based and touch-free cursor interaction that accurately tracks the motion of fingers in real-time. We also present "IndexPen," an interaction mode that can successfully identify 29 distinct characters, representing the letters A-Z, as well as Space, Backspace, and Enter. We investigate the technical and design considerations of the combined system to enable new in-air, micro, tracking-based interaction.
