Vibrating TV screen puts people's voices where their mouths are
Imagine having a conversation and seeing the other person's lips move, but hearing the sound coming from their feet. While our brains can mostly compensate, this disconnect occurs with many big-screen display technologies. Visuals come from different areas of the screen, but the accompanying sound comes from speakers or soundbars positioned elsewhere. Researchers at the Korea Institute of Machinery and Materials (KIMM) have developed a display technology that lets you hear sound from the exact area of the screen where the action happens.
The new modular-grid-based audiovisual convergence display technology uses multiple vibration actuators attached to the rear of a display to emit sound from selected sections of the screen, effectively turning the entire panel into a giant, highly controllable speaker.
This means that if a talking person appears at the top left of the screen, their voice will also come from that area, roughly around where their mouth is....
