Turn nearly any TV into a touchscreen with the Touchjet Wave. This diminutive device uses infrared sensors to detect finger movements, letting it support both taps and gestures. It runs Android 4.4, so it supports tons of apps, includes an IR stylus, so you can save your screen from fingerprints, and clips to the top of your TV, letting it support screens up to 80 inches in size and resolutions up to 4K at 30fps over HDMI.
