Touch Display Media Scanning via Gesture-Controlled Grid Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in locating specific digital media on touch displays due to the lack of intuitive navigation methods, which can be frustrating and dangerous, especially when attention cannot be fully devoted to the task.
Innovation Solution
A system and method utilizing a touch-sensitive display with a two-dimensional grid of images, where gestures control the movement of an indicator to preview and play media files, allowing users to scan through media collections without requiring full attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users navigate through sequences of menus and options to locate specific media, then they can find the desired media item, but the process requires full user attention and is time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically scanning and playing media files in sequence without requiring user intervention. The indicator automatically moves through the grid and media plays sequentially, allowing users to passively review content before making a selection, thus eliminating the need for active navigation through menus
Solution Approach 2:
The system serves itself by automatically navigating through the media collection using the gesture-based scanning mechanism. Once a scanning gesture is detected, the system autonomously moves the indicator through the grid and plays media files sequentially without requiring further user input, enabling hands-free operation
2Ease of operation
If traditional buttons of different shape, size, or location are used for navigation, then navigation can be intuitive, but touch displays lack these physical navigation aids
Solution Approach 1:
The touch display serves multiple functions: it displays the grid of media thumbnails, detects scanning gestures, tracks indicator position, and provides visual feedback for media playback. This multi-functional approach eliminates the need for separate physical navigation buttons while maintaining intuitive operation through direct touch interaction
Solution Approach 2:
The system changes the operational parameters of the touch display by implementing gesture-based control. Instead of requiring precise taps on specific buttons, the system recognizes scanning gestures (swiping motions) and translates them into automatic indicator movement through the grid, making navigation more intuitive and less error-prone
3Reliability
If users manually navigate through media collections, then they can locate specific media, but the process is frustrating when attention cannot be fully devoted
Solution Approach 1:
The system provides continuous feedback by playing media files sequentially as the indicator moves through the grid. Users receive auditory feedback from each media file while the display shows which item is currently being previewed, allowing them to make informed selections without needing to actively navigate or pay constant attention to the interface
Data Source
AI summary
A device configured for a scanning preview of digital media includes: a database, a touch-sensitive display, and a processor. The database is configured to store a plurality of media files and a plurality of images, each image of the plurality of images corresponding to a media file of the plurality of media files. The touch-sensitive display is configured to display an indicator and a two-dimensional grid, the two-dimensional grid including the plurality of images the indicator indicating a first image of the two-dimensional grid. The processor is configured to: play a first media file corresponding to the first image; detect a first gesture on the touch-sensitive display; move the two-dimensional grid displayed on the touch-sensitive display in response to detecting the first gesture such that the indicator indicates a second image of the two-dimensional grid; and play a second media file corresponding to the second image.
