When it comes to motion capture, each device manufacturer has two rough technical routes. The most commonly used is the radar module and infrared perception module in the handle, which use optical vision technology to transmit the position of the hand to the host or headset through the handle. Whether it is Inside-out or outside-in, it is achieved by using optical technology to capture the position of the opponent. The other is a wearable device, such as the HTC Vive tracker tracker, which uses the technical route of lidar and IMU inertial sensors to install an action tracking device on the user's body and capture position through lidar. To prevent laser blocking due to operating occlusion, the IMU (Inertial Measurement Unit) provides signal complement.
In order to improve the tactile experience effect of users in the virtual world, major manufacturers are also launching their own technical solutions. Last November, Meta introduced tactile gloves, which allow users to feel the sensation of grasping objects through ridge-like inflatable plastic sheets, as well as the touch of surfaces touching various materials. In June last year, haptic feedback company bHaptics launched the tactile vest bHaptics TactSuit, which allows users to wear the product to play supported games and experience the feeling of being attacked in the game. Last December, bHaptics unveiled its first consumer-grade haptic glove, Tactglove, a product that users can feel rolling in their hands.
In general, there are more and more products that support users to carry out stereoscopic sensing in the metaverse, but from the actual situation, such products have problems such as insufficient market application, slow technical iteration, difficult technical breakthroughs, and lack of motivation to solve technical problems. "Did not meet the expected product update speed", which is probably the true portrayal of stereoscopic sensing products in the metaverse.
