Systems and methods are disclosed for providing a virtual mouse for a computing device have a touchscreen. A first placement region of the touchscreen may be determined. The first placement region may then be determined to contain a first portion of at least one touch target. The first portion of the at least one touch target may then be deactivated. A virtual mouse may then be activated at the first placement region.

Virtual mouse for electronic touchscreen display

There is described a method performed by a computing device having first and second touch-sensitive user interfaces. According to this method, when a user input is applied to one of the first and second user interfaces, the computing device detects the user input and determines a force applied by the user input and a type of the user input. The computing device then determines whether to perform a function such as whether to display a virtual trackpad or a virtual keyboard, based on the force, the type of the user input, and a determination whether the user input is applied to a selected one of the first and second user interfaces.

Methods, devices, and computer-readable storage media for performing a function based on user input

A method to correct a haptic output, the method including sending, at a device, a reference tactile signal to a haptic actuator and recording, using a sensor associated with the haptic actuator, an output signal from the haptic actuator. This output signal could be provided, along with the reference tactile signal to an engine at the device, which could be used to determine regions of perceptual distortion from the output signal and the reference tactile signal. Specifically, a perceptual similarity measure could be determined which could be used to generate an adapted signal to reduce and equalize the perceptual distortion, where the adapted signal could be provided to the haptic actuator to control adaptation or equalization of distortions.

A method, a feedback-enabled device and a computer-readable memory are provided, for generating haptic feedback. The actuators of a tactile surface are vibrated for producing vibration bursts based on a sequence of an adaptive friction grain signal. The adaptive friction grain signal comprises a plurality of grains corresponding to the vibration bursts, each grain being defined by an amplitude. The adaptive friction grain signal has a grain density that is variable over the sequence.

There is provided a pointing device including a mode switching apparatus that switches the pointing device between a two-dimensional (2D) operational mode and a three-dimensional (3D) operational mode and a sensor configured to determine a pointing direction of the pointing device and locations of a plurality of computing devices. When in the 2D operational mode, the pointing device is paired with a first computing device of the plurality of computing devices and controls the first computing device and when in the 3D operational mode, the pointing device is configured to select a second computing device of the plurality of computing devices additionally to control, the selection based on one or more of the pointing direction of the pointing device and the location of the second computing device.

Devices, systems, and methods for multi-device interactions

Devices, methods and systems for controlling an electronic device using force-based gestures are described. Force data from one or more force sensors, representing a force input to the electronic device, is monitored to determine any force data exceeding a defined first magnitude threshold. In response to determining force data from at least one force sensor exceeding the first magnitude threshold, an edge location or a corner location of the force input is determined. The force input is processed as a force gesture in accordance with the determined edge location or the determined corner location. Haptic feedback is generated concurrently with processing the force gesture.
