Electronic Device Selection Logic for Screen Item Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for selecting items on a display unit require excessive operation steps to reach items at opposite ends, and often result in selecting locations far from the intended location, especially when dealing with a large number of items.
Innovation Solution
An electronic device with an acceptance unit and control unit that allows for optimized movement operations on a screen, where attempting to move an item at an end results in no movement if it's already at the end, and moving a selected location is directed towards the opposite end only when necessary, thereby reducing unnecessary steps and improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movement operation is performed to select an item at the opposite end when already at an end, then the item at the opposite end can be selected, but the number of operation steps increases
Solution Approach 1:
The patent applies dynamics by making the selection behavior adaptive based on the current state. When an item at the end is selected and the operation continues, the system dynamically changes from maintaining the same selection to selecting the opposite end item, optimizing the operation flow based on the detected state
2Adaptability or versatility
If a movement operation moves the selected location to the opposite end, then the selection can be changed, but the selected location becomes far from the intended location
Solution Approach 1:
The patent applies preliminary anti-action by preventing the harmful effect of overshooting the intended selection. When the selected location is at an end and movement operation is detected, the system proactively prevents moving to the opposite end, thereby avoiding the error of selecting a location far from the intended one

AI summary
An electronic device includes a control unit and an acceptance unit to accept an operation to move a selected location on a screen in which items are positioned. When moving a particular item not located in a first direction at an end of selectable locations, the particular item is moved in the first direction. Where the particular item is located in the first direction at the end of the selectable locations, the particular item is not moved. In response to selecting a selectable locations without moving any item, a selected location is moved to a location in the first direction from the location being currently selected. Where the location in the first direction being currently selected is at the end of the selectable locations, the selected location is moved, in a direction opposite the first direction, from the location being currently selected to a location at a selectable locations end.
