Abstract: Embodiments of the invention provide a human interface device including an inner sphere, wherein the inner sphere has a center point. The human interface device can further include an outer sphere, and the outer sphere may be compressible. The human interface device may also include a plurality of pressure sensors between the inner sphere and the outer sphere for detecting localized compression of the outer sphere, a first three-axis-accelerometer located within the inner sphere, and a second three-axis-accelerometer located within the inner sphere, wherein the first three-axis-accelerometer and the second three-axis-accelerometer-accelerometer are each located at least a predetermined distance from the center point.
