    Abstract: Technologies for touch point detection include a computing device configured to receive input frames from a touch screen, identify touch point centroids and cluster boundaries, and track touch points. The computing device may group cells of the input frame into blocks. Using a processor graphics, the computing device may dispatch one thread per block to identify local maxima of the input frame and merge centroids within a touch distance threshold. The computing device may dispatch one thread per centroid to detect cluster boundaries. The computing device may dispatch one thread per previously identified touch point to assign an identifier of a previously tracked touch point to a touch point within a tracking distance threshold, remove duplicate identifiers, and assign unassigned identifiers to closest touch points. The computing device may dispatch one thread per block to assign unique identifiers to each unassigned touch point. Other embodiments are described and claimed.

    Abstract: In an embodiment, a processor includes a graphics domain including a graphics engines each having at least one execution unit. The graphics domain is to schedule a touch application offloaded from a core domain to at least one of the plurality of graphics engines. The touch application is to execute responsive to an update to a doorbell location in a system memory coupled to the processor, where the doorbell location is written responsive to a user input to the touch input device. Other embodiments are described and claimed.

    Abstract: An apparatus for fast inking a touch display is described herein. The system for fast inking a touch display can include receiving touch input and generate touch sensor data. The system can include a graphics processing unit (GPU) including a fast inker and a display pipeline. The GPU can transmit human interface device (HID) data generated from the touch sensor data to a writing application memory and the fast inker. The fast inker can convert the HID data into inking data to be sent to the display pipeline through a direct hardware path. The writing application can convert the HID data into inking data to be sent to the display pipeline. The system can also include a touch display to display pixels marked according to the inking data received by the display pipeline.
