Abstract: Various systems and methods for adapting a computer based on user attentiveness are described herein. A system for attention-based gesture recognition includes processing circuitry to: access an image of a user, the user proximate to a computing device; determine, based on the image, whether user is attentive to the computing device; and selectively enable or disable a function of the computing device depending on whether the user is attentive.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for reduced computing device power consumption. Example methods disclosed herein includes detecting frame updates corresponding to input frames to be presented by a display, causing a programmable timer to generate second interrupts corresponding to first interrupts generated by a display engine, the second interrupts to be generated when there are no frame updates detected for at least a first duration of time defined by a first threshold. Example methods further include causing the display engine to transition to a low power state when (1) the programmable timer is configured to generate the second interrupts and (2) no frame updates have been detected for at least a second duration of time following the first duration of time, the second duration of time defined by a second threshold.

Abstract: A method for power-efficient touch input, in which touch sensor data from a touch input is obtained by touch circuitry. Touch sensor data is obtained from touch input at touch circuitry included in a device that also includes a system-on-a-chip (SOC) and a display controller stack outside of the SOC. The touch sensor data is stored in a buffer. When the SOC is in a low-power state, the touch sensor data is communicated to the display controller stack for immediate display.

Abstract: Technology for a display controller is described. The display controller can detect a frame update when the display controller is in a dynamic sleep state. The display controller can wake up from the dynamic sleep state and enter a selective update state at a programmed vertical blanking interrupt (VBI) that precedes an actual VBI. The display controller can perform a scan-out with a display panel during the selective update state. The display controller can return to the dynamic sleep state in a same time frame after the scan-out is completed. The display controller can exclude timing logic to send a VBI at every time frame to the display panel to maintain time synchronization between the display controller and the display panel.
