A system can use electrical signals from the body to control infrared appliances such as a television. Electrodes capture signals produced by blinks or muscle movements, Neuro PlayGround Lite detects them, and its ESP32-based hardware sends the corresponding infrared remote command.

The Neuro PlayGround Lite can measure small biopotential signals including EEG, EMG, ECG and EOG. In this example, the practical control is less science-fiction mind reading than turning eye and muscle signals into new physical input buttons. The project was demonstrated by Upside Down Labs.
