Yet another new HP “pen/touchscreen” patent application…

Posted: 8 February, 2016 in Anoto, Published Investment Calls

Title: CONTROLLING FORMS OF INPUT OF A COMPUTING DEVICE

Applicant: Hewlett-Packard Development company L.P.

“Examples disclosed herein control computing device input. One example includes activating a touchscreen of a computing device and enabling a capacitive touch control of the computing device for user selection as a device input to initiate a device action. The example further includes disabling the capacitive touch control based on a pen event with the touchscreen, wherein the pen event is triggered when a digital pen is to be placed within a predefined distance from the touchscreen.”

“In addition to the touchscreen, the display surface of such computing devices may include buttons, for example, as a device input to initiate a device action. As an example, a device may include a home button for returning to the home screen, or a back button for returning to the previous screen illustrated on the device. Examples of buttons disposed on the display surface include, but are not limited to, physical buttons, that get physically depressed when pressed, and buttons with a capacitive touch control, that are capacitively activated due to user touch.

By having multiple forms of input on the display surface of the device (e.g., the touchscreen and the buttons), it is critical that the operation of one form of input does not interfere with the operation of another form of input. For example, while a user interacts with the touchscreen, either using a finger or a digital pen, the user may accidentally touch another form of input, such as the home button (e.g., by the palm or wrist). As a result, the home button controller may mistake unintentional touch as an attempt to return to the home screen. This false trigger on the home button may affect the seamlessness of the user’s work.

Examples disclosed herein provide the ability for disabling or ignoring input from one form of input on the display surface of a computing device while input is being received from another form of input on the display surface. For example, while a digital pen is interacting with the touchscreen of a tablet computer, the buttons disposed on the display surface of the tablet may be disabled, or input from the buttons may be ignored. By disabling or ignoring input from one form of input while input is being received from another form of input, false triggers due to unintentional touch may be avoided.

In one example, a method generally includes activating a touchscreen of a computing device and enabling a capacitive touch control of the computing device for user selection as a device input to initiate a device action. The method includes disabling the capacitive touch control based on a pen event with the touchscreen, wherein the pen event is triggered when a digital pen is to be placed within a predefined distance from the touchscreen.

In another example, a computing device generally includes a touchscreen and a first controller to activate the touchscreen. The computing device includes a capacitive touch control for user selection as a device input to initiate a device action and a second controller electrically connected to the first controller. The second controller is to enable the capacitive touch control for the user selection, and ignore the device input from the capacitive touch control based on a pen event with the touchscreen. The pen event is triggered when a digital pen is to be placed within a predefined distance from the touchscreen.

In yet another example, a computing device, generally includes a non-transitory computer-readable storage medium and a plurality of programming instructions stored in the storage medium. In response to execution of the programming instructions by a processing resource, the computing device is to activate a first form of input of the computing device and enable a second form of input of the computing device for user selection as a device input to initiate a device action. The computing device is to disable the second form of input based on a pen event with the first form of input, wherein the pen event is triggered when a digital pen is to be placed within a predefined distance from the first form of input.”
