Virtual Reality, with Feeling
In the past, external cameras have been used to monitor the movement of facial features as a means of adding emotion to VR. The new system, developed by Emteq, uses small sensors embedded into a VR headset to measure electrical signals, heart rate, and muscle movement. According to Engineering & Technology, that allows the system, known as Faceteq, to capture a wider range of emotional response than visual approaches.
...observing another person’s emotions in the virtual world could add an extra layer of realism.
It’s not the only approach being used to make VR more convincing. A small startup called Midas Touch Games is developing more accurate physics engines to help make human movement in the virtual world look more realistic, and the likes of Dolby are trying to make 3-D sound as convincing as possible.
