Solution Overview

Problem

Touch interfaces in consumer devices, such as phones and tablets, pose challenges for users wearing gloves, as the large size of gloved or ungloved fingertips makes it difficult to accurately select icons without inadvertently touching adjacent ones, leading to a need for improved touch interface solutions that balance icon size with display space efficiency.

Innovation Solution

Implementing proximity sensing technology to dynamically adjust the size and visibility of user interface elements based on the presence and proximity of an input device, such as a hand or stylus, allowing for adaptive and efficient display of UI elements only when needed, thereby optimizing screen space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If icon size is made large to enable accurate touch selection, then ease of operation is improved, but display space for content is reduced

Engineering Contradiction:
Improveease of touch selectionVSAvoiddisplay space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The icon size is made dynamic rather than static. Icons automatically enlarge when a user's hand approaches the display (proximity detected within threshold distance) and return to normal size when the hand moves away. This allows icons to be large during interaction for ease of touch selection, while maintaining small size at other times to preserve display space.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The physical parameter of icon size changes based on proximity detection. When proximity sensor detects hand within threshold distance, icon size parameter increases; when hand moves beyond threshold, icon size parameter decreases. This parameter change resolves the contradiction by adapting icon size to operational needs.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If icon size is made large to avoid inadvertently touching adjacent icons, then reliability of selection is improved, but display space is reduced

Engineering Contradiction:
Improveselection accuracyVSAvoiddisplay space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

Icon size dynamically adapts to user proximity. When hand approaches, icons enlarge to improve selection reliability and prevent accidental touches. When hand recedes, icons shrink to maximize display space. This dynamic behavior allows the system to achieve high reliability only when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary enlargement of icons before the user actually touches them. By detecting hand proximity in advance and pre-enlarging icons, the system ensures selection reliability is established before the critical touch action occurs, preventing inadvertent selections.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If UI elements are displayed continuously, then ease of operation is improved, but loss of display space for content is increased

Engineering Contradiction:
Improveaccessibility of UI elementsVSAvoiddisplay space loss
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

UI element visibility is dynamic. Elements are hidden when no hand is detected within threshold distance, and automatically appear when hand approaches. This ensures UI elements are accessible only when needed, minimizing display space loss while maintaining ease of operation during interaction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system periodically checks proximity and adjusts UI element visibility accordingly. UI elements are displayed during proximity periods when interaction is needed, and hidden during non-proximity periods to preserve display space for content.

Inventive Principle:
Principle #19Periodic action

AI summary

Described herein are techniques for adaptively displaying graphic elements (e.g., user interface elements) on a display of a device based on sensing proximity of an input device (e.g., a hand or fingertip of a user, a stylus, etc.) to the display of the device. For example, in response to an input device being detected to be less than a threshold distance from the display of the device, one or more graphic elements are presented or dynamically resized on the display. However, in response to no input device being detected to be less than the threshold distance from the display, the one or more graphic elements are not presented or are maintained in their current size on the display.
