Three-state gesture virtual controls
A hand interaction system can use a three-state model to differentiate between normal hand movements, such as reaching for an object, and hand input gestures. The three-state model can specify a sequence of states including: 1) a neutral state, 2) a tracking state, and 3) an active state. In the neutral state, the hand interaction system monitors for a gesture signaling a transition to the tracking state but does not otherwise interpret a gesture corresponding to the active state as input. Once a gesture causes a transition to the intermediate tracking state, the hand interaction system can recognize a further active state transition gesture, allowing active state interaction. Thus, the monitoring for the intermediate tracking state provides a gating mechanism, making it less likely that the hand interaction system will interpret hand movements as input when not so intended by the user. |

RF-DAC digital signal modulation
Radar frequency range signals (e.g., 1 to 100 gigahertz) are often generated by upconverting a reference frequency to a transmission frequency, and a received signal may be downconverted to analyze information encoded on the transmission via modulation.

Instead, a clock generator may generate clock signals for a digital front end comprising a digital signal modulator that generates modulated digital values comprising quadrature representations of a radar modulation signal, which are encoded by a radiofrequency digital-to-analog converter (RF-DAC). The RF-DAC analog signal may be upconverted to a radar frequency and transmitted.
