Touch Screen External Device Movement Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with large displays require multiple menu processing steps for users to access information and struggle to distinguish between multiple users, leading to low usability when multiple users try to check their information simultaneously.
Innovation Solution
An electronic device and method that displays information related to an external electronic device on a touch screen by moving the external device relative to the touch screen, allowing users to access information without additional procedures and distinguishing between users based on movement and registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple menu processing steps are required to access information, then information security and system control are improved, but user operation time and complexity increase
Solution Approach 1:
The system performs preliminary user identification by detecting the movement of the external electronic device towards the touch screen before full interaction begins. This preliminary action establishes user context in advance, allowing the system to prepare and display relevant information without requiring multiple subsequent menu steps, thus reducing operation time while maintaining security through progressive authentication.
Solution Approach 2:
The patent enables skipping of intermediate menu steps by directly displaying target information when the external device's movement pattern indicates the user's intent. The system analyzes movement characteristics (speed, direction, duration) to infer the desired information type and jumps directly to displaying that information, bypassing traditional multi-step navigation while maintaining system control through movement-based authentication.
2Device complexity
If a limited user interface shape and size are used, then device design simplicity is improved, but information display capability and user experience deteriorate
Solution Approach 1:
The patent introduces a new dimension for information display by utilizing the spatial relationship between the external electronic device and the touch screen. Instead of expanding the physical interface size, the system uses the three-dimensional movement space around the device as an additional dimension for organizing and displaying information. Different positions and movement patterns of the external device correspond to different information categories, effectively expanding display capability without increasing physical interface complexity.
Solution Approach 2:
The user interface transitions from a static, fixed-layout design to a dynamic, movement-responsive interface. The display content and layout automatically adjust based on the detected movement characteristics of the external device. This dynamic adaptation allows the limited physical interface to present different information configurations without requiring multiple fixed interface designs, maintaining simplicity while enhancing information display capability.
3Reliability
If traditional user distinction methods are used, then system security is improved, but usability for multiple users simultaneously deteriorates
Solution Approach 1:
The system implements self-service user identification by automatically detecting and analyzing the movement characteristics of each user's external device. Instead of requiring users to manually log in or select their profiles, the system autonomously identifies users based on their device's movement patterns (speed, trajectory, duration, acceleration). This automatic user distinction maintains security through unique movement signatures while dramatically improving multi-user usability by eliminating manual authentication steps.
Solution Approach 2:
The system continuously monitors and provides feedback on the movement of external devices to distinguish between different users. By analyzing real-time movement data and comparing it against stored user profiles, the system can identify which user is attempting to access the device and adjust the interface accordingly. This feedback mechanism enables secure multi-user support without requiring traditional authentication procedures, as each user's movement pattern serves as a unique identifier.
