An electronic device is disclosed. The electronic device can sense touch on its touch screen while in a sleep state in a manner that allows the electronic device to respond to certain touch inputs, while consuming less power due to touch sensing than while in an awake state. For example, sensing touch during the sleep state can allow the electronic device to wake (e.g., transition from the sleep state to the awake state) in response to detecting a certain touch input (e.g., a tap or other touch input) on its touch screen while in the sleep state. Various ways for the electronic device to sense touch during the sleep state are disclosed.

Low power touch sensing during a sleep state of an electronic device

This application relates to an electronic device that includes a processor and a display assembly overlaid by a protective cover. The display assembly can include a touch detection system capable of detecting a touch event at the protective cover. The touch detection system can include a capacitance detector capable of detecting a change in capacitance and a location corresponding to the change in capacitance, and an applied force detector capable of detecting an amount and a location of a force applied to the protective cover that is associated with the touch event. The electronic device can include a moisture detector capable of detecting an amount of moisture present at the protective cover, where when the amount of moisture is greater than a threshold amount, the processor determines a position of the touch event based on detection signals provided by the capacitance detector and the applied force detector.

Modifying functionality of an electronic device during a moisture exposure event

This application is directed to modifying a sensed velocity at a device (e.g., a clickable trackpad) based on a time-dependent click memory variable (CMV). For example, if a touch having a certain velocity is detected when a selection (pick) button is pressed or released, the velocity can be initially suppressed under the presumption that the movement was inadvertent. However, over time that presumption fades, and the CMV can be used to gradually allow the full velocity of the touch to be recognized, under the new presumption that the movement was intentional.

Selective input signal rejection and modification

A touch sensor panel is disclosed. The touch sensor panel includes a plurality of rows, at least one of the rows being a split row including a plurality of row subsections; and a plurality of columns, at least one of the columns being a split column including a plurality of column subsections. The touch sensor panel is configured with at least one split row and at least one split column located to increase a likelihood that a touch anywhere on the touch sensor panel overlaps with at least one split row and at least one split column. The rows and columns are individually charged electrodes capable of detecting a change in capacitance in a corresponding area of the touch sensor panel.

Method for disambiguating multiple touches on a projection-scan touch sensor panel

Improved capacitive touch and hover sensing with a sensor array is provided. An AC ground shield positioned behind the sensor array and stimulated with signals of the same waveform as the signals driving the sensor array may concentrate the electric field extending from the sensor array and enhance hover sensing capability. The hover position and/or height of an object that is nearby, but not directly above, a touch surface of the sensor array, e.g., in the border area at the end of a touch screen, may be determined using capacitive measurements of sensors near the end of the sensor array by fitting the measurements to a model. Other improvements relate to the joint operation of touch and hover sensing, such as determining when and how to perform touch sensing, hover sensing, both touch and hover sensing, or neither.

Touch and hover sensing

Power consumption of touch sensing operations for touch sensitive devices can be reduced by implementing a coarse scan (e.g., banked common mode scan) to coarsely detect the presence or absence of an object touching or proximate to a touch sensor panel and the results of the coarse scan can be used to dynamically adjust the operation of the touch sensitive device to perform or not perform a fine scan (e.g., targeted active mode scan). In some examples, the results of the coarse scan can be used to program a touch controller for the next touch sensing frame to idle when no touch event is detected or to perform a fine scan when one or more touch events are detected. In some examples, the results of the coarse scan can be used to abort a scheduled fine scan during the current touch sensing frame when no touch event is detected.

Coarse scan and targeted active mode scan for touch

A method for dynamically modifying a characteristic for an electronic device. The method includes activating by a processor a first profile having a first characteristic setting and a first state for an input/output (IO) device. Once the first profile is activated, receiving an input by a sensor and communicating the input to the processor. The method then includes activating by the processor a second profile having a second characteristic setting and a second state for the IO device. The second profile modifies a component of the IO device to include a second characteristic setting and a second state.

Dynamic parameter for multiple types of inputs based on different input profiles for electronic input/output (I/O) devices

A touch input device configured to synchronize a stylus acquisition process with both a touch data acquisition process and a display refresh process is provided. The touch input device can include one or more processors that can synchronize the stylus data acquisition process to the touch data acquisition process by coordinating stylus scans to take place in between touch scans. The one or more processors can also virtual data banks to synchronize both the touch data acquisition and the stylus scan acquisition with the display refresh process.

Display, touch, and stylus synchronization

An intelligent stylus is disclosed. The stylus can provide a stylus condition in addition to a touch input. The stylus architecture can include multiple sensors to sense information indicative of the stylus condition, a microcontroller to determine the stylus condition based on the sensed information, and a transmitter to transmit the determined condition to a corresponding touch sensitive device so as to cause some action based on the condition.

Intelligent stylus

Accurate and reliable techniques for determining information of an accessory device in relation to an electronic device are described.

Embodiments are related to user input devices that accept complex user input including a combination of touch and push (or pick) input. Embodiments of the invention provide for selective ignoring or rejection of input received from such devices in order to avoid interpreting unintentional user actions as commands. Furthermore, some input signals can be modified. The selective rejection or modification can be performed by the user interface device itself or by a computing device that includes or is attached to the user interface device. The selective rejection or modification may be performed by a module that processes input signals, performs the necessary rejections and modifications and sends revised input signals to higher level modules.

Systems and methods related to providing peripheral device functionality is described herein. In one embodiment, a method of operating a host computing device is described. The method includes communicatively coupling with a keyboard and querying the keyboard for a descriptor. Receiving the descriptor from the keyboard, wherein the descriptor includes data representative of a language, layout, and key mappings for the keyboard. Storing the data from the descriptor at the host and publishing strings for proper translation and interpretation of input received from the keyboard.
