Dynamic Display Timing via Motion Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartwatches with backlit displays face battery life issues due to inconsistent and arbitrary display timing solutions, which fail to accommodate users' varying needs for display duration.
Innovation Solution
A method and system that utilize a database of correlated motions to dynamically control the display state of wearable and mobile devices, adjusting power based on user interactions, such as gestures, button presses, eye contact, and voice commands, to personalize the display on and off timing.

1Speed
If the display is kept on for a fixed amount of time (e.g., 10 seconds), then the user can quickly check the time at a glance, but users who need to ponder the display for a longer period experience frustration
Solution Approach 1:
The patent implements dynamic display timing by transitioning from static fixed-duration display control to adaptive timing based on detected user gestures. The system dynamically adjusts display duration by detecting whether the user is wearing or unwearing the device, ensuring the display remains on during wearing gestures and turns off during unwearing gestures, thereby adapting to real-time user needs
Solution Approach 2:
The system enables self-service by automatically detecting user intent through motion sensors and gesture recognition algorithms. The display controller autonomously determines when to turn the display on or off based on detected gestures (wearing/unwearing motions), eliminating the need for manual user input while adapting to individual usage patterns
2Ease of operation
If various solutions are implemented to turn the display on when user interaction is detected, then the display becomes more responsive to user needs, but battery life is reduced due to unnecessary power consumption
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring motion sensor data to detect user gestures. The system uses this feedback to intelligently control display timing, turning the display on when wearing gestures are detected and off when unwearing gestures occur, thereby optimizing power consumption based on actual user interaction patterns rather than using fixed timing
Solution Approach 2:
The system changes the parameter of display duration from fixed values to variable values based on detected gesture types. By categorizing gestures into wearing gestures (extending display on-time) and unwearing gestures (reducing display on-time), the system optimizes power consumption while maintaining responsiveness to user needs

AI summary
A method of controlling the display of an electronic devices that includes measuring a motion of a device; and determining if the motion of the device and the display state of the device at the time of motion match conditions in a database of motions that are correlated to display states that signal a change from the display state at the time of the motion to a called display state. The method may further include adjusting power from a battery to the display to effectuate a change of display state in response to motion of the device matching conditions in the database of motions that signal the change of display state or a user intervention signaling a change in display state. The method further includes updating a database of motions in response to changes in the display state effectuated by user intervention.
