Abstract: A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HIVID, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HIVID. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HIVID. The sensors translate muscle movements of the upper face of the user to changes in the bending strain and radius of curvature on the surface of the strain gauges. The HIVID includes a module that reconstructs and projects a facial animation model of the user based on signals from the deformation sensors while the HIVID is in use by the user.

Abstract: Examples of the disclosure provide an active matrix capacitive touch sensor. In some examples, a sensor includes a plurality of primary ring oscillators, a plurality of reference ring oscillators, wherein each reference ring oscillator is associated with a respective primary ring oscillator, at least one row trace, wherein each row trace is coupled to at least one primary ring oscillator and a reference ring oscillator for each primary ring oscillator, at least one sensor column trace coupled to one primary ring oscillator for each row trace, and at least one reference column trace coupled to one reference ring oscillator for each row trace. Examples of the disclosure enable touch-screen technology to provide increased pad sensitivity and multi-touch capability in a cost-effective and scalable manner.

Abstract: The stylus directional force sensing technique described herein employs a directional tip sensor which measures the magnitude and direction of force applied to a stylus tip. This information is then used to control the behavior of the stylus in an application. In one embodiment, this simple design only measures the stylus angle when the tip is actually pressing on the surface. This has the added benefit of reducing power requirements and computational complexity.

Abstract: A minimal access tool includes a frame arranged to be attached to an arm of a user, a tool shaft having a proximal end and a distal end, where the tool shaft proximal end is connected to the frame. The tool further includes an input joint having a first end connected to the frame and a second end arranged to receive user input, the input joint including a virtual center-of-rotation (VC) mechanism which provides a center of rotation that generally coincides with a wrist joint of the user. An output joint is connected to the tool shaft distal end, where the output joint is coupled to the input joint via a mechanical transmission connected therebetween to correlate motion of the input joint to motion of the output joint.

Abstract: A physically-modulated friction stylus system and method for physically modulating friction between a styli tip and a surface of a computing device to emulate the “feel” of different types of writing instruments writing on different types of surfaces (such as pen on paper or a paintbrush on canvas). The actual friction between the stylus and the surface is modulated to produce the “feel.” The friction is physically modulated “on the fly” meaning that friction can be modulated while the stylus tip is in contact with the surface and while the stylus is moving. The friction is modulated dependent on a location of the stylus on the surface and the posture and orientation of the stylus. In addition, the friction can be modulated based on a direction and a velocity that the stylus tip is moving across the surface. Audio may also be used to improve the emulation experience.
