Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-functional computing devices with sensitive displays face usability issues due to complex operations and limitations in small form factors, particularly when used with tiny displays and speakers, necessitating improved user interfaces for better interaction with remote media-playing devices.
Innovation Solution
A method for a user interface that detects taps and hovers on sensitive displays, enabling popup dialogs, menus, and assistant objects, as well as communication with remote display devices to enhance usability by displaying video signals and indicators, allowing for easier interaction with tappable objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sensitive display is used to enable intuitive operations, then ease of operation is improved, but device complexity increases due to additional detection mechanisms
Solution Approach 1:
The patent combines the display function and sensing function into a single integrated sensitive display component. The display panel and sensor array are merged into one structure, allowing the display to simultaneously present visual information and detect user inputs (taps, hovers, gestures) without requiring separate physical components.
Solution Approach 2:
The sensitive display serves multiple functions: it acts as both a visual output device and a multi-modal input device capable of detecting taps, hovers, and various gestures. This universal component replaces what would traditionally require separate buttons, switches, or touch sensors, thereby improving ease of operation while managing device complexity through consolidation.
2Volume of moving object
If the computing device is made small for mobility, then portability is improved, but usability deteriorates due to tiny display and speaker limitations
Solution Approach 1:
The patent utilizes the Z-dimension (depth/proximity) in addition to the traditional X-Y plane interactions. By detecting hover states and proximity-based gestures above the display surface, the system creates a third dimension for user interaction, allowing more complex operations to be performed on the small display without requiring physical buttons or larger form factor.
Solution Approach 2:
The interaction model transitions from static tap-based input to dynamic multi-state input including hover, proximity detection, and gesture recognition. The system dynamically adapts its response based on the user's finger proximity and movement patterns, enabling richer interaction capabilities on the tiny display while maintaining device portability.
3Ease of operation
If popup dialogs are displayed at tap locations, then ease of operation is improved, but reliability deteriorates due to erroneous taps on dialogs
Solution Approach 1:
The system performs preliminary detection of hover state before triggering the tap action. By detecting when the user's finger hovers over or near a tappable object, the system can prepare the popup dialog in advance and position it appropriately, preventing erroneous taps by ensuring the user intends to interact with the correct element before the dialog appears.
Solution Approach 2:
The patent introduces an intermediary hover detection mechanism between the user's finger and the final tap action. This intermediate hover state serves as a mediator that allows the system to anticipate user intent, position popup dialogs more accurately, and prevent erroneous interactions by detecting unintended tap locations before the actual tap occurs.
4Ease of operation
If hover detection is added to the sensitive display, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The hover detection capability is merged into the existing sensitive display structure. Rather than adding a separate hover sensor system, the patent integrates proximity and hover detection functions into the same sensor array that detects taps and gestures, allowing multiple interaction modes from a single integrated component.
Data Source
AI summary
A user interface at a computing device with a sensitive display is disclosed. A dialog is popped up, on the sensitive display, at a position that is predetermined pixels away from the position of hover or a tap of an object detected by the sensitive display. A menu for operation of a computer program is displayed responsive to such hover being detected above a predetermined location within a screen of the computer program on the sensitive display. An assistance object for assisting a tappable object to be tapped is displayed responsive to such hover being detected above the tappable object on the sensitive display. A tappable object is emphasized responsive to such hover being detected above the tappable object on the sensitive display.
