Display Control Apparatus Group Indication for Symbol Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may not reliably recognize information on a symbol corresponding to a pointing position, even when an object is displayed, due to difficulties in accurately identifying the symbol amidst multiple options, especially on small display devices where the object can be obscured by the user's finger.
Innovation Solution
A display control apparatus and method that visibly displays a plurality of symbols and acquires pointing position information to control the display of a predetermined object indicating the group to which the symbols belong, allowing for easier recognition by highlighting the relevant group and reducing the likelihood of incorrect pointing between groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an object is displayed on a symbol of a pointing position, then the user can potentially recognize information on the symbol, but the user may still not reliably recognize the symbol due to obscuration by finger or difficulty in accurately identifying the symbol amidst multiple options
Solution Approach 1:
The invention divides the display into multiple groups of symbols and displays an object indicating the group containing the pointed symbol, rather than directly displaying on the specific symbol. This segmentation allows the user to first identify the relevant group, reducing the search space and making symbol recognition more reliable even when individual symbols may be obscured.
Solution Approach 2:
The invention introduces an intermediate indicator (object indicating the group) between the user's pointing action and the final symbol identification. This intermediary group indicator serves as a mediator that guides the user to the correct symbol group, reducing the direct impact of finger obscuration and improving recognition reliability.
2Loss of information
If an object is displayed on a symbol of a pointing position, then information on the symbol can be shown, but the user may not reliably recognize the symbol due to difficulty in accurately identifying it amidst multiple options
Solution Approach 1:
The invention segments the symbols into multiple groups and displays an object indicating which group contains the pointed symbol. This segmentation reduces the information search complexity by dividing the full set of symbols into smaller, more manageable groups, making it easier for users to locate and identify the correct symbol.
Solution Approach 2:
The invention provides feedback by displaying an object that indicates the group containing the pointed symbol. This feedback mechanism guides the user by confirming which group is relevant, reducing the difficulty of symbol identification and ensuring information is delivered effectively without loss.
3Quantity of substance
If multiple symbols are displayed, then more information can be provided to the user, but the user may not reliably recognize the pointing position due to increased complexity and potential obscuration
Solution Approach 1:
The invention divides the large number of symbols into multiple groups and displays an object indicating the relevant group. This segmentation allows a large quantity of symbols to be displayed while maintaining pointing accuracy, as the group indicator reduces the effective search space and helps users reliably identify the correct region even when many symbols are present.
Solution Approach 2:
The group-indicating object serves as an intermediary that bridges the gap between displaying multiple symbols and maintaining pointing accuracy. It provides an additional layer of information that helps users correctly identify the pointing position among many symbols, reducing the negative impact of increased symbol quantity on recognition reliability.

AI summary
Provided is a display control apparatus including a display control unit that controls a display unit in a manner that a plurality of symbols is visibly displayed to a user, and a position acquisition unit that acquires information indicating a pointing position for specifying one or more symbols among the plurality of symbols. The display control unit controls the display unit in a manner that a predetermined object is displayed to indicate a group to which the plurality of symbols belongs according to the pointing position.
