Rotary Pointer Navigation for Compact Display Event Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in displaying and managing large amounts of data efficiently due to limited screen space, making it difficult for users to identify correlations between data items, especially as display units become more compact.
Innovation Solution
An electronic device with a display method that includes an information area, an item area at the edge, and a pointer, allowing users to rotate and move the pointer to select event items, displaying corresponding event information, and utilizing a rotary unit for input, enabling easy management of multiple events on a compact screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display unit is made more compact, then the device size is reduced, but the amount of data that can be displayed is limited
Solution Approach 1:
The patent transitions from traditional linear or grid-based data arrangement to a circular dimension. Event items are arranged along the circumference of a circular display area, allowing continuous navigation around the circle. This dimensional change enables more efficient use of screen space while maintaining accessibility to multiple data items simultaneously.
Solution Approach 2:
The display area is segmented into distinct functional zones: a circular item area for event items, a central information area for detailed information, and a pointer indicator. This segmentation allows each zone to serve its specific purpose efficiently, with the item area displaying multiple events around the circumference and the information area providing detailed information about the selected event.
2Productivity
If multiple events are displayed simultaneously, then user efficiency is improved, but the complexity of managing and navigating events increases
Solution Approach 1:
The patent implements dynamic navigation where the pointer rotates to indicate different event items in sequence. Users can rotate the display or use input mechanisms to move the pointer through events in a natural circular motion. This dynamic approach replaces complex multi-step selection processes with intuitive rotational navigation, making it easier to manage multiple events.
Solution Approach 2:
The pointer serves as an intermediary element between the user and the event items. Instead of requiring users to directly interact with multiple event items, the pointer mediates the selection process by indicating which event is currently selected. This intermediary simplifies the interaction model, as users only need to control the pointer's position rather than directly manipulating each event item.
3Loss of information
If detailed event information is displayed for each item, then information completeness is improved, but the screen space for displaying multiple items is reduced
Solution Approach 1:
The patent extracts detailed event information from the item area and places it in a separate central information area. The circular item area displays only compact event item indicators (such as icons or abbreviated text), while the central area provides comprehensive event details. This extraction allows multiple event items to be displayed around the circumference without compromising the completeness of information for the currently selected event.

AI summary
An electronic device and a screen display method thereof are described. In one aspect, a display is configured to display a screen that includes an information area, an item area disposed at the edge of the information area, and a pointer configured to point within the item area, where the item area is configured to display at least one event item, and a controller is configured to control the display to move the pointer based on a rotation input and to display event information of an event item to which the pointer points, in the information area.
