> An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs.[1]
Moasure does displacement estimation with inertial measurement (in a mobile app w/ just accelerometer or also compass sensor data?) IIUC:

Are there a limited set of possible-path-corresponding diffraction patterns that NIRS (Near-Infrared Spectroscopy) could sense and process to make e.g. a magic pencil with pressure sensitivity, too?
> Can low-cost lasers and Rdyberg atoms e.g. Rydberg Technology solve for [space-based] matter-wave interferometry? [...] Does a fishing lure bobber on the water produce gravitational waves as part of the n-body gravitational wave fluid field, and how separable are the source wave components with e.g. Quantum Fourier Transform/or and other methods?
There are infrared depth cameras in various phones and laptop cameras now.
