A chair capable of providing somatosensory vibration based on an external signal comprises a body, a plurality of vibrators and a vibration controller. The body comprises a framework and a plurality of mesh fabrics disposed on the framework. The vibrators are hung on the framework through at least two connectors and are arranged corresponding to one of the mesh fabrics. Each of the plurality of vibrators is provided with a vibration surface directly contacting one of the mesh fabrics. Each of the plurality of vibrators operates based on at least one vibration starting signal. The vibration controller is disposed on the body and is in data connection with the vibrators. The vibration controller generates at least one vibration starting signal based on a received external signal, and provides at least one vibration starting signal to each of the plurality of vibrators in a wired or wireless manner.

A haptic device includes a housing, a first motor configured to rotationally drive a first lead screw, a second motor configured to rotationally drive a second lead screw, and a touch point configured to contact the skin on a distal end. The rotation of the first lead screw is configured to move the touch point along a first axis and the rotation of the second lead screw is configured to move the touch point along a second axis The second axis can be perpendicular to the first axis. The haptic device can be configured to be worn on a user's arm via a wrist band or compression sleeve.

A multimodal haptic feedback interface installed with a multimode haptic patch stimulates a skin area of a user to provide a haptic feedback including first and second haptic-feedback components to be sensed under static tactile sensing and dynamic tactile sensing, respectively. The patch is mounted with mechanical actuators, electrostimulation electrodes and thermoelectric pellets. The actuators generate a two-dimensional pattern of pressure on the skin area for generating the first haptic-feedback component. The electrostimulation electrodes electrically stimulates the skin area, causing the user to feel a vibration or pressure for generating the second haptic-feedback component. The actuators and electrostimulation electrodes are optimized only for static tactile sensing and dynamic tactile sensing, respectively, reducing an implementation cost while optimized for accuracy in haptic feedback generation. The thermoelectric pellets, realized as Peltier-effect heat pumps, generate a two-dimensional pattern of temperature change on the skin area for providing a thermal feedback to the user.

A haptic system is described. The haptic system includes a linear resonant actuator (LRA), a receiver, and a transmitter. The LRA has a characteristic frequency and provides a vibration in response to an input signal. The receiver is configured to sense received vibration from the LRA. The transmitter is configured to provide the input signal to the LRA. The receiver is coupled with the transmitter and provides vibrational feedback based on the received vibration. The input signal incorporates the vibrational feedback.

Described herein are head orientation training devices for sports training and systems including such devices. A head orientation training device (HOTD) can include a position sensor configured to sense a tilt of the device, continually, while the device is activated. The HOTD can also include a computing device, configured to retrieve the tilt of the device from the position sensor, repeatedly, while the apparatus is activated. Also, the computing device of the HOTD can be configured to activate an alarm (such an audible or a visual alert) when the tilt of the apparatus exceeds a tilt threshold. The tilt threshold can be user definable as well.
