By applying resistance through its magnetic friction brakes, SenseGlove emulates the feeling of size and stiffness. The Nova incorporates four brakes dedicated to each finger from thumb to ring finger. Each brake delivers up to 20N of force, which is equivalent to the weight of a 2 kg brick on each finger and makes for unparalleled force feedback. The different amounts of force, transferred to the fingertips through mechanical wires, allows SenseGlove to enhance training simulations with a wide variety of virtual objects, from robust engines and tools to fragile light bulbs.
Vibrotactile feedback
SenseGlove has embedded an advanced voice coil actuator technology that allows the Nova to render the feeling of realistic button clicks, vibrations and impact simulations, which are crucial for virtual reality training with tools and dashboards. Both the thumb and the index finger have their own vibrotactile actuator, while the voice coil actuator is located in the hub of the glove.
Finger tracking
SenseGlove Nova combines sensor-based finger tracking with computer vision hand tracking algorithms. There are 4 sensors to capture the flexion and extension of the thumb, the index, the middle and the ring fingers, plus 1 sensor to capture the abduction and adduction of the thumb. These movements are captured by measuring the extension of the cables on the Nova Glove.
Motion tracking updates
Due to a limited access to the camera data of some headsets SenseGlove gloves also use external tracking like controllers or trackers on top of the gloves. The additional trackers can be easily attached with a use of SenseGlove mounts provided with the gloves. We are working on our own computer vision Glove tracking which will need no external tracking solution attached.
