Air Gesture Interaction Icon Trajectory Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience poor user experience and high misoperation rates when performing air gestures with electronic devices, as they cannot sense whether the device detects their inputs correctly.
Innovation Solution
An air gesture-based interaction method where an electronic device displays a first display interface, detects air gestures using a camera, moves an indication icon along the gesture's trajectory, and updates the interface accordingly, allowing users to see the execution progress of their gestures in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air gesture recognition is implemented without real-time feedback, then the device can recognize gestures, but user experience deteriorates and misoperation rate increases
Solution Approach 1:
The patent implements real-time feedback by displaying an indication icon that moves along with the detected air gesture trajectory. This visual feedback allows users to see whether their gestures are being detected correctly and understand the execution progress, thereby improving user experience while maintaining gesture recognition accuracy.
2Device complexity
If no visual feedback is provided during gesture input, then the interface remains simple, but users cannot sense gesture detection status
Solution Approach 1:
The patent introduces an indication icon as an intermediary element that visually represents the air gesture trajectory and execution progress. This icon serves as a mediator between the user's gesture input and the system's recognition output, providing essential feedback information without significantly complicating the interface.
3Loss of information
If the indication icon moves along the complete gesture trajectory, then execution progress is visible, but processing complexity increases
Solution Approach 1:
The patent implements partial trajectory tracking by moving the indication icon along a simplified or representative path of the gesture rather than every single coordinate point. This approach provides sufficient execution progress feedback to users while avoiding excessive processing complexity associated with tracking every detail of the gesture trajectory.

AI summary
An air gesture-based interaction method includes displaying, by an electronic device, a first display interface of a first application; detecting, by the electronic device by using a camera, a first air gesture input by a user; moving, by the electronic device, an indication icon on the first display interface along a moving trajectory of the first air gesture in a preset direction in response to the first air gesture; and displaying, by the electronic device, a second display interface of the first application in response to the first air gesture.
