Touch Panel Gesture Overlay for Ambiguous Input States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gesture input systems on touch panel displays require users to remember multiple trajectory data sets, leading to incorrect inputs and ambiguity in determining whether the device is accepting gesture inputs, as users cannot distinguish between software accepting or not accepting gestures.
Innovation Solution
An electronic device with a touch panel display and a control unit that stores trajectory-related information, allowing the device to determine if gesture input is accepted and overlay trajectory data on the display, enabling users to recognize acceptance or rejection of gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple trajectory data sets are stored for gesture input, then the functionality and versatility of the device is improved, but the user must remember multiple trajectories which increases the difficulty of operation and leads to incorrect inputs
Solution Approach 1:
The patent applies preliminary action by displaying guide trajectories before the user performs the gesture input. The control unit displays the guide trajectory on the touch panel display in advance, allowing the user to see the expected trajectory pattern before drawing it, thereby eliminating the need to remember multiple trajectory data sets while maintaining versatile gesture functionality
2Productivity
If gesture input is implemented on touch panel display, then input efficiency is improved, but users cannot determine whether the device is accepting gesture inputs which reduces operational reliability
Solution Approach 1:
The patent implements feedback by displaying the guide trajectory on the touch panel display when gesture input is accepted. This visual feedback mechanism allows users to recognize whether the device is in a state of accepting gesture inputs, as the guide trajectory is displayed only when the corresponding software is running and ready to receive gestures, thereby improving operational reliability while maintaining input efficiency
3Adaptability or versatility
If software that does not respond to gesture input displays data on the touch panel, then display functionality is maintained, but users cannot distinguish why gesture input is not executed which increases operational complexity
Solution Approach 1:
The patent applies the color changes principle by using different display states to indicate software compatibility with gesture input. When gesture input is accepted, the guide trajectory is displayed on the touch panel; when not accepted, the trajectory is not displayed. This visual differentiation helps users quickly diagnose why gesture input is not executed, simplifying operation while maintaining software compatibility

AI summary
An electric device supports gesture input, so a user can determining whether the electric device is in a state of accepting the gesture input. An electronic device includes a touch panel display, a storage unit for storing sets of display data and trajectory related information that is associated with each set of display data, and a control unit. The trajectory related information includes trajectory data and function information that is associated with the trajectory data, and the control unit determines whether or not to accept the gesture input on the basis of the trajectory related information that is associated with the display data displayed on the touch panel display. When having determined to accept the gesture input, overlay-displays on the touch panel display, the trajectory data included in the trajectory related information that is associated with the display data so as to be overlaid on the display data.
