Dynamic Display Speed Control for Touch Slider Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In slide-bar operating apparatuses, users face difficulties in finding desired information due to the large amount of information being displayed, making it challenging to accurately position the slider and locate specific data.
Innovation Solution
A display apparatus and input apparatus that utilize a touch panel with detecting areas to detect user input, allowing for dynamic display control by determining target display numbers and adjusting the display range to ensure a smooth transition of information, with a first display processing that rapidly moves through a large range and a second processing that slows down near the target, facilitating easier information selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the slider moves quickly through a large range to display many informations, then the display speed is improved, but the user cannot accurately stop at the desired information position
Solution Approach 1:
The patent applies dynamics by changing the display speed according to the slider position. When the slider is far from the target position, the display updates quickly (first display processing). When the slider approaches the target position, the display updates slowly (second display processing). This dynamic speed adjustment allows both fast traversal and precise positioning.
Solution Approach 2:
The patent changes the parameter of display update speed based on the slider position relative to the target position. The system transitions between two display processing modes: fast update mode for distant positions and slow update mode for nearby positions, effectively using parameter changes to resolve the contradiction.
2Quantity of substance
If the total amount of informations to be displayed is large, then the information coverage is improved, but the user spends more time searching for desired information
Solution Approach 1:
The system dynamically adjusts the display update speed based on the user's proximity to the target information. During the initial phase when covering large information ranges, the display updates quickly to reduce search time. When approaching the target, it slows down to allow precise selection, thus balancing information coverage with search efficiency.
Solution Approach 2:
The patent applies skipping by rapidly displaying informations when the user is far from the target position, allowing the system to cover large information ranges quickly. This rushing through of distant informations reduces the overall search time while still maintaining the ability to access comprehensive information.

AI summary
A display apparatus, wherein a display controller configured to perform a first display processing in which display informations from a starting point display number to a second target display number which is between the starting point display number and a first target display number corresponding to an approach-touch area are displayed on a display portion as to-be-displayed informations such that a difference between the display number of the to-be-displayed informations displayed at a start and an end of a unit time is a first value, and then perform a second display processing in which display informations from the second target display number to the first target display number are displayed as the to-be-displayed informations such that a difference between the display number of the to-be-displayed informations displayed at a start of an end of the unit time is a second value which is smaller than the first value.
