MindMaze developed a cost-effective VR HMD upgrade called Mask that can detect biosignals in your face to bring your facial expressions and emotional queues into VR experiences to help improve virtual social interactions.
Social VR experiences, which let you communicate and share activities with other people from around the world, are incredibly compelling. Oculus proved that when it showed off Toybox for the first time, and platforms like AltspaceVR, VRChat, and Rec Room as well as co-op games like Arizona Sunshine and Raw Data reinforce the idea.
In the real world, emotional expression is a large part of face-to-face communication. You can tell a lot about a person’s demeanor and intent from the expressions on their face, irrespective of the words they are saying. In VR, you don’t have the luxury of seeing the face of the person you’re talking to, so you can’t pick up on such emotional cues. The developers of VRChat mapped several facial expressions to the thumbstick/trackpad on your controller to address this problem, but those expressions aren’t natural, which means they aren’t a reliable gauge of that person’s mood.
