I thought this was around the corner years ago when Intel and partners had RealSense modules being built into laptops but it seems like all the players have shifted focus to more enterprise and industrial markets.
> 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.
