Methods and apparatus to improve user experience on computing devices are disclosed. An example computing device includes an image sensor. The example computing device further includes wireless communication circuitry. The example computing device also includes an operations controller to cause the wireless communication circuitry to switch between different operation modes based on an analysis of image data generated by the image sensor. Different ones of the operation modes to consume different amounts of power.

Methods and apparatus to improve user experience on computing devices

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.

Dynamic sleep for a display panel

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.

User attention-based user experience

Example smart panel display apparatus and related methods are disclosed herein. An example apparatus to control a display of an electronic device includes a user presence detector to determine a presence of a user relative to the device based on image data generated by an image sensor of the device. The example apparatus includes a gaze detector to determine a direction of a gaze of the user relative to the image sensor based on the image data. The example apparatus includes a backlight manager to selectively adjust a display brightness based on the presence of the user and the direction of the gaze of the user.

Smart display panel apparatus and related methods

Techniques for selective display frame fetching are disclosed. Some example techniques disclosed herein cause at least one processor to at least determine if an indication of a new frame includes an indication of a flip event, and identify one or more dirty regions of the new frame based on the flip event. Disclosed example techniques also cause the at least one processor to fill a display buffer with the one or more dirty regions of the new frame, scan out the one or more dirty regions of the new frame from the display buffer to a display port, and apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Devices and methods for selective display frame fetch

Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can obtain an indication of a new frame and, in response to the indication of the new frame not including an indication of a flip completion event: (i) fill the display buffer with the new frame; (ii) scan out the new frame from the display buffer to a display port; and (iii) apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

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, and 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.

Apparatus and methods for reduced computing device power consumption

There is disclosed in one example a computing apparatus, including: a main board including a processor and memory; a user-facing (UF) camera including an auto-exposure (AE) circuit; an ambient light sensor (ALS); and a power management module communicatively coupled to the UF camera and the ALS, and including logic to detect a light input mismatch between the ALS and the AE and responsive to the detection, disable a power management function of the power management module.

Detection of user-facing camera obstruction

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.

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.
