Mobile Terminal Menu List End Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals lack effective feedback mechanisms to inform users when they reach the end of a displayed menu list during scrolling, which can lead to user confusion and inconvenience in navigating and searching through extensive lists.
Innovation Solution
A mobile terminal with a display unit and a controller that provides visual, audible, or tactile feedback when the user scrolls to the end of a list, using graphic effects, sounds, or vibrations to indicate the list's termination, enhancing user interaction and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a list is scrolled without feedback mechanism, then the scrolling operation is simple, but the user cannot know when reaching the end of the list
Solution Approach 1:
The patent applies color changes to the display background or list items when the user reaches the end of the list. The controller detects the scrolling position and changes the display color (e.g., from white to yellow or red) to provide visual feedback, informing the user they have reached the list end without adding complex mechanical components.
Solution Approach 2:
The patent employs vibration feedback through the mobile terminal's vibration motor. When the scrolling reaches the list end, the controller activates the vibration motor to produce tactile feedback, allowing the user to sense the list boundary through touch without requiring additional display elements or complex mechanisms.
2Ease of operation
If graphic effects are displayed to indicate list end, then user feedback is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic or temporary graphic effects rather than continuous display. The color change or graphic effect is activated only momentarily when the list end is reached, then returns to the normal state. This periodic activation provides necessary user feedback while minimizing energy consumption compared to continuous display effects.

AI summary
A mobile terminal having a touch screen or a touch pad is disclosed. In a user environment, when a displayed menu list is moved according to a flicking operation, a feedback indicating the reaching of the end (the last item) of the menu list is issued in a visible, audible or tactile manner to a user, thereby increasing the user convenience of menu searching and the durability of the mobile terminal.
