Particular embodiments further determine that: (1) the touch events are approaching an edge of the touchscreen, and (2) one or more pressure measurements taken at one or more of the touch input events are less than a minimum pressure threshold. Based on the determinations, particular embodiments anticipate that the touch events will end before they reach the edge of the touchscreen, and based on the anticipating, particular embodiments terminate a series of extrapolated positions before the series of extrapolated positions reach the edge of the touchscreen.

  • Patent number: 10591995
    Abstract: A gaming concept in which each user in a single-player or a multi-player game is enabled to create artwork or graffiti work virtually or on actual surfaces using haptic-enhanced controllers. The controllers can emulate the experience of using a marker, a paint brush, a paint spray-can or the like. The components of various controllers may be modularized for easily interchanging components to extend the art or graffiti creation experience. The real life experience of using ink or paint on a surface is simulated by haptic feedback. When a paint spray-can controller is used, the experience of paint consumption is recreated by various peripheral enhancements including audio and haptic sensations communicated to the user.

  • Patent number: 10585524
    Abstract: An input control for controlling various features of an electronic device is described. The input control can be positioned along an exterior surface of the electronic device and cover an opening leading into the electronic device. A pressure sensor can then be positioned within the electronic device and adjacent to the covered opening. The pressure sensor is able to measure a pressure of a volume of air positioned between the pressure sensor and the input control. When movement of the input control changes the pressure of the volume of air, the sensor readings from the pressure sensor can be used to register a user input. The input control can take many forms including rocker buttons, slider switches and input regions.

  • Patent number: 10578499
    Abstract: Systems and methods of creating a touch sensitive surface structure comprising a piezo structure in communication with a deformable surface such that the piezo structure, or any suitable pressure sensing device, is capable of sensing pressure from a touch upon the deformable surface and communicating that pressure signal to an actuating circuit. The actuating circuit, upon receiving a suitable pressure signal, sends a piezo actuating signal to the piezo structure. The piezo structure, upon receiving the piezo actuating signal, is capable of communicating a mechanical signal to the deformable surface, sufficient for a person's finger to feel a “click” and/or haptic sensation. In one embodiment, the piezo actuating signal comprises a first slow charging portion and a second fast discharging portion, sufficient for the piezo structure to communicate the click and/or haptic sensation.
