We introduce a dynamic weight moving VR controller for 2d haptic shape rendering using a haptic shape illusion. This allows users to perceive the feeling of various shapes in virtual space with a single controller. We designed a device that drives weight on a 2d planar area to alter mass properties of the hand-held controller. Our user study showed that the system succeeded in providing shape perception over a wide range.

We present a biped robot which can move agiler than conventional robots. Our robot can generate bipedal walking motion automatically using the proposed method. By using a quadrotor for balance and movement it is possible to make an agiler movement, and generate a gait interactively and in real time according to the motion of the quadrotor using the optimized control policy of the legs. Our system takes the velocity of the quadrotor as an input and legs motions are produced so that the velocity of the foot in contact with the ground to zero, and bipedal walking motion is generated. The control policy is optimized using reinforcement learning with a physics engine.

We present a transmissive mirror device (TMD) based near-eye see-through displays with a wide viewing angle and high resolution for virtual reality and augmented reality. In past years, many optical elements, such as transmissive liquid-crystal display (LCD), half-mirror, waveguide and holographic optical element (HOE) have been adopted for near-eye see-through displays. However, it is difficult to obtain wide field of view with see-through capability for beginner developer. To accomplish this, we develop a simple see-through display that easily setup from a combination of off-the-shelf HMD and TMD. In the proposed method, we render "virtual lens," which has the same function as the HMD lens in the air. By using TMD, it is possible to shorten the optical length between the virtual lens and the eyeball. Therefore, the aerial lens provides a wide viewing angle with see-through capability. We demonstrate a prototype with a diagonal viewing angle of 100 degrees.
