Display Cursor Control for Separated Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminal devices where the display portion and touch input portion are separated, users face difficulties in moving their line of sight between the touch input surface and the display, making it cumbersome to select icons due to the need to look away from the display to input touches.
Innovation Solution
A display control device that receives operation information from a touch input portion and controls the display to position a cursor among circumferentially disposed icons, allowing easy movement of the cursor to selected icons through slide operations, tangential movements, and center positioning, facilitating intuitive touch input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keys are set on the touch input surface, then the functionality of the device is improved, but the user's line of sight must move between the touch input surface and the display portion, making operation cumbersome
Solution Approach 1:
The patent creates a visual copy of the touch input interface on the display portion by showing icons that correspond to the keys. This allows users to see the icon positions on the display while touching the corresponding keys on the touch input surface, eliminating the need to shift gaze between the two components.
Solution Approach 2:
The patent introduces a cursor as an intermediary element that is displayed on the display portion and moves in response to touch operations. The cursor serves as a visual mediator that connects the touch input actions with the corresponding icons, allowing users to track icon selection without directly viewing the touch keys.
2Device complexity
If icons are disposed in a non-circumferential arrangement, then the display layout is simpler, but the cursor movement requires more complex multi-directional operations
Solution Approach 1:
The patent arranges icons in a circumferential (circular) pattern around the center of the display portion. This curved arrangement allows the cursor to move along the circumference in a natural sliding motion, making it easier to navigate between adjacent icons compared to linear or grid-based layouts that require precise positioning.
Solution Approach 2:
The patent pre-arranges icons in a circumferential pattern with predictable positioning, allowing users to anticipate icon locations and perform slide operations in expected directions. This preliminary organization of icons reduces the cognitive load and physical effort required for cursor movement.

AI summary
A display control device includes a receiving portion configured to receive operation information input to a touch input portion, the touch input portion being located away from a display portion; and a processing portion configured to control display on the display portion in accordance with the operation information that is received by the receiving portion. The processing portion is configured to cause the display portion to display an image in which a cursor is disposed inside a plurality of icons that are circumferentially disposed, and the processing portion is configured to move the cursor to an icon among the plurality of icons, the icon being located in a direction of a slide operation received by the receiving portion.
