There was some development in osgBullet for grappling with a data glove and hand model. Without haptics, the user had no feedback over how tightly the objects were grasped, and Bullet had difficulty resolving the constraints in this situation.
We found a better approach was to detect gestures with the data glove, such as fist, point, open, etc., and use those as a signal to the application for creating and removing different types of constraints between the hand model and a target object in the scene. This approach allowed for very easy scene interaction, and no issues with Bullet constraint resolution.
