Screen Interaction Method for Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen electronic devices in public areas face challenges in determining which user's actions to prioritize for screen control when multiple users are present, leading to conflicts and poor user experience.
Innovation Solution
The method involves using a camera to capture images of users, recognizing their actions, and identifying a target user based on preset actions such as arm movements or gestures, allowing the device to control the screen accordingly, even in scenarios with multiple potential users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device responds to actions of multiple users simultaneously, then the device can serve all users, but control conflicts occur and user experience deteriorates
Solution Approach 1:
The patent introduces preset actions (such as specific hand gestures or body movements) as intermediaries between users and the electronic device. The camera captures user actions, and the processing unit determines whether the action matches a preset action to identify the target user. This intermediary mechanism filters out casual movements and ensures only intentional control actions are recognized, resolving control conflicts while maintaining multi-user support capability.
2Measurement precision
If the electronic device uses preset actions to identify target user, then control accuracy improves, but the system complexity increases
Solution Approach 1:
The electronic device performs self-identification of the target user by automatically capturing actions via camera, processing the action data, and determining match results without requiring external intervention. The system autonomously manages the complexity of preset action recognition and target user identification, achieving high accuracy while keeping the user interface simple.
3Speed
If the electronic device captures and processes user actions in real-time, then responsiveness improves, but processing time and computational resources increase
Solution Approach 1:
The patent pre-defines specific preset actions (such as specific hand gestures or body movements) that trigger control functions. By having these actions predetermined and clearly defined, the processing unit can efficiently compare captured actions against the preset templates, reducing computational complexity and processing time while maintaining real-time responsiveness.

AI summary
A screen interaction method and apparatus for an electronic device are disclosed, to determine a target user from a plurality of users and control a picture displayed on a screen of the electronic device based on an action of the target user. The method includes: obtaining, by using a camera, an image including the plurality of users in front of a screen, recognizing respective actions of the plurality of users in the image based on the image including the plurality of users, comparing the actions of the plurality of users with a preset action, determining a user who performs an action matching the preset action as the target user, and controlling a picture displayed on the screen of the electronic device based on the action of the target user.
