Gesture-Based Display Control for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in efficiently managing limited screen space and power consumption, requiring users to fully awaken or unlock the device to access notifications, communications, and applications, which is inefficient and power-intensive.
Innovation Solution
Implementing a gesture-based system that detects user input to selectively display categories of selectable items, such as notifications, communications, and applications, without fully waking the device, using a combination of touch, spatial, and audible inputs to preview information and allow direct access without unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the device is fully awakened to display all information, then the user can access all notifications, communications, and applications, but the power consumption increases significantly
Solution Approach 1:
The display area is segmented into multiple portions, with each portion displaying a specific category of selectable items (e.g., notifications, communications, applications). This allows the device to display only relevant information in each segment rather than all information simultaneously, reducing power consumption while maintaining accessibility to different types of content.
Solution Approach 2:
The device displays a subset of available information (partial action) by showing only selected categories of items in the first display portion, rather than displaying all information. This partial display approach reduces power consumption while still providing users with access to key information without requiring full device awakening.
2Weight of moving object
If the display size is decreased to improve portability, then the device becomes more portable, but the available screen space for displaying information is limited
Solution Approach 1:
The patent utilizes the temporal dimension by implementing a gesture-based navigation system that allows users to access different categories of information across multiple display portions over time. This enables a small display area to effectively present a larger amount of information by cycling through different categories, compensating for the limited screen real estate while maintaining device portability.
Solution Approach 2:
The limited display area is segmented into multiple functional portions, with the first display portion showing a category of selectable items and the second display portion showing additional items. This segmentation allows efficient use of the limited screen space by organizing information into manageable categories that can be accessed through gestures.
3Loss of information
If the device requires full awakening and unlocking to access information, then all information is accessible, but the process is time-consuming and inefficient
Solution Approach 1:
The device maintains a partially active state where the display is awakened and ready to show information, but full system unlocking is not required. The first display portion is prepared to show selectable items, and users can quickly access information through simple gestures without completing the full unlocking sequence, thus reducing access time while keeping information accessible.
Solution Approach 2:
The system performs partial awakening (display activation without full system unlock) to provide quick access to information. This partial action allows the display to show selected categories of items without requiring the complete awakening and unlocking process, significantly reducing the time needed to access information while maintaining security for full system access.

AI summary
A method comprises detecting, by a portable electronic device having a display, a gesture, selecting a category of selectable items based on the gesture. The method further comprises identifying one or more selectable items within the selected category to be displayed, and displaying the one or more selectable items.
