Touch Panel Trajectory Extension for Single-Handed Object Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel devices require users to hold the device differently and often need a second hand to select objects that are at a distance, making intuitive manipulation less efficient.
Innovation Solution
A method that enters a trajectory extension mode when the user moves their finger over the touch panel at a speed equal to or greater than a predetermined speed, extending and displaying the finger's trajectory, and placing the object at the end point of the trajectory in a selected state, allowing for intuitive selection and manipulation of distant objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device uses a traditional touch panel interface, then the user can directly touch objects on the screen, but the user requires a second hand or different holding position to select distant objects
Solution Approach 1:
The patent introduces a trajectory extension mechanism as an intermediary between the user's finger and distant objects. When the user performs a quick swipe gesture, the system extends the trajectory beyond the finger's actual endpoint to reach distant objects, allowing single-handed operation without requiring the user to physically touch the distant object
Solution Approach 2:
The system performs preliminary calculation and extension of the trajectory based on the user's swipe gesture characteristics (speed, direction) before the user releases their finger. This preliminary action determines the final selection target, enabling the user to select distant objects without needing to precisely position their finger at the exact object location
2Ease of operation
If the user reaches for distant objects on the screen, then the object can be selected, but the user must hold the device differently and may require another hand
Solution Approach 1:
The patent extends the interaction from the two-dimensional touch surface to a third-dimensional trajectory space. By extending the trajectory beyond the screen boundaries based on the swipe direction and speed, the system allows users to access distant objects while maintaining a consistent one-handed holding position, eliminating the need to adapt holding positions for different object locations
3Measurement precision
If the touch panel requires precise finger placement on distant objects, then accurate selection is achieved, but the operation becomes less intuitive and more difficult
Solution Approach 1:
The system creates a virtual copy or extension of the user's finger trajectory that reaches beyond the physical finger position. This trajectory copy allows the user to select distant objects by swiping from a comfortable position, with the system calculating the extended trajectory to accurately reach the intended target without requiring precise finger placement at the object's location

AI summary
Embodiments relate to selecting an object to display from an information processing device connected in a manner enabling the exchange of data to a touch panel having a display function. An aspect includes entering a trajectory extension mode in response to the user moving a finger over the touch panel at a speed equal to or greater than a predetermined speed. Another aspect includes extending and displaying a trajectory of the finger in response to the speed of the moving finger detected in the trajectory extension mode. Yet another aspect includes placing an object located at an end point of the extended trajectory on the touch panel in a selected state.
