Dynamic Reference Axis Adjustment for Gesture Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices face difficulties in accurately controlling external devices, such as TVs, due to misinterpretation of input directions when not directly viewing the screen, leading to unintended events being executed.
Innovation Solution
An input processing method and apparatus that adjusts the reference axis of a display based on user input angles, allowing for precise execution of events on external devices, such as channel switching or volume changes, by determining the correct axis for processing user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display area is reduced to make the electronic device smaller and lighter, then the device portability is improved, but the user's tactile sensation for distinguishing display areas becomes insufficient
Solution Approach 1:
The patent introduces a reference object (e.g., another electronic device or a specific UI element) as an intermediary to provide tactile reference points. When the user performs gestures, the system references the position and orientation relative to this intermediary object to determine the intended action, compensating for the lack of tactile feedback on the small display surface.
2Ease of operation
If the user does not directly watch the display, then the user can focus on the external device screen, but the user input direction may be misinterpreted leading to unintended events
Solution Approach 1:
The patent dynamically adjusts the reference axis based on the detected orientation of the electronic device and the position of the reference object. Instead of using a fixed reference axis, the system calculates and applies a rotated reference axis that aligns with the user's intended gesture direction, thereby maintaining high input recognition accuracy even when the user is not watching the display.
3Adaptability or versatility
If the display is used to control external devices with gesture inputs, then the device functionality is enhanced, but misinterpretation of drag direction occurs due to device orientation and viewing angle
Solution Approach 1:
The patent changes the reference parameter (reference axis) dynamically based on the device's physical orientation and the detected gesture context. By adjusting the reference axis angle according to the device rotation and gesture position, the system accurately interprets gesture directions regardless of how the device is held or oriented, enabling reliable remote control functionality.

AI summary
A method for processing an input is provided. The method includes obtaining a user input through a display that is functionally connected to an electronic device, determining an angle corresponding to the user input by defining a first axis for the display as a reference axis, determining a second axis for the display as the reference axis based on at least the angle, and performing at least one event corresponding to the user input on at least one external device that is functionally connected to the electronic device, based on the second axis.
