Touch Slider Playback Control for Animation Speed Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems for displaying animations or videos on a display face operability issues due to the need for multiple buttons for controlling playback, pause, and reverse playback, leading to cumbersome user interactions.
Innovation Solution
A program that continuously plays animations or videos until a user input is detected, allowing for simple operation by starting, pausing, or reversing playback based on user input, and enabling speed control through positional changes on the display, thereby simplifying user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are provided for controlling animation playback (forward, pause, backward), then playback control functionality is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent merges multiple playback control functions (forward, pause, backward) into a single slider component. The slider can be dragged in different directions and positions to execute different playback operations, eliminating the need for separate buttons for each function while maintaining full playback control capability.
Solution Approach 2:
The slider is designed as a universal control element that performs multiple functions: dragging left executes backward playback, dragging right executes forward playback, and dragging to specific positions controls playback speed. This multi-functional design replaces multiple specialized buttons with a single versatile control.
2Adaptability or versatility
If multiple buttons are provided for controlling animation playback, then playback control functionality is improved, but ease of operation deteriorates due to repeated operations near pause position
Solution Approach 1:
By combining forward, pause, and backward controls into a single slider mechanism, the patent eliminates the need for users to repeatedly locate and click multiple buttons near the pause position. The slider provides all controls in one unified interface, improving ease of operation.
Solution Approach 2:
The patent transitions from one-dimensional button clicking (requiring multiple discrete clicks in a small area) to two-dimensional slider dragging (providing continuous control across a larger area). This dimensional change allows users to control playback by dragging in different directions and positions, making operations more intuitive and easier.

AI summary
An information processing apparatus includes a processor, and the processor acquires a touch coordinate from an input device, and when a state is changed from a touch-off to a touch-on, plays an animation or video based on a touch position of the touch-on. Moreover, the processor changes, if detecting a slide when playing the animation or video, a speed of playing the animation or video based on a magnitude of the slide. The processor pauses playing of the animation or video if the touch-off is detected when playing the animation or video.
