SYSTEMS AND METHODS FOR PROVIDING HAPTIC FEEDBACK RELATED TO LIFTING OR MANIPULATING A VIRTUAL OBJECT

Abstract:

A hand-held device for providing haptic feedback includes an elongated housing, a mass, a mass restriction device, a first sensor and a second sensor. The elongated housing includes at least two chambers. The mass is slidably disposed within the chambers and is slidable by gravity. The mass restriction device restricts the mass within at least one of the chambers. The first sensor is configured to sense an orientation of the elongated housing and the second sensor is configured to sense a location of the mass within the elongated housing relative to the chambers. In response to a command signal indicative of a virtual interaction related to manipulating a virtual object, the mass restriction device restricts the mass within at least one of the chambers to effect a perceived change in weight as the virtual object is manipulated by the user.
