  • Patent number: 9746942
    Abstract: An optical touch pen includes a pen case, an operation module, and a power module. The operation module is disposed within an upper cover of the pen case, and includes a pen tip, a supporting part, a circuit board and a multi-directional auxiliary element. The multi-directional auxiliary element is arranged between an inner wall of the upper cover and the engaging structure of the supporting part. The power module is disposed within a lower cover of the pen case. When an external force is applied to the pen tip, the pen tip and the supporting part are shifted in response to the external force, the engaging structure of the supporting part is shifted relative to the multi-directional auxiliary element, and the external force is transmitted downwardly to the circuit board. Consequently, a current switch on the circuit board is triggered and the power module is electrically conducted.

    Abstract: Computing devices are disclosed that use haptic technology to communicate data to a stylus device. This data may include, for example, updates to the stylus device, instructions on how the stylus should behave, authentication and identification information, and other data. This communication may also allow a stylus to implement security features and copy and paste functionality from one user device to another. In an aspect, the computing device includes a haptic element that provides a vibration force to the device or touchscreen of the device, and communicates data embedded on a carrier to the stylus. The stylus receives the vibration force through a pressure sensor on the stylus and used the information to enhance the user experience.
