Solution Overview

Problem

Existing touch screen interfaces require multiple steps and physical contact to control applications, which can be time-consuming and drain battery resources, especially on mobile devices.

Innovation Solution

A system that detects hover gestures above the touch screen using capacitive sensing, allowing for the presentation of a control interface without physical contact, using a combination of touch screen sensors, gesture engines, and rendering engines to interpret and respond to finger movements and their absence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple icons are selected to control an application through a control panel, then the application can be controlled, but the user spends more time and battery resources

Engineering Contradiction:
ImproveTime to control applicationVSAvoidTime spent selecting multiple icons
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The control panel is pre-configured with multiple control icons that are immediately available for selection. When a user hovers over a virtual element, the relevant control panel is automatically presented with all necessary controls already in place, eliminating the need for users to navigate through multiple screens or select icons sequentially to access control functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control panel serves multiple functions simultaneously by providing various control options (play, pause, skip, volume, etc.) in a single interface. This multi-functional approach allows users to access different control capabilities without needing to switch between different screens or modes, reducing the number of steps required to control the application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a control panel with multiple icons is presented to control an application, then the application can be controlled, but battery life is wasted

Engineering Contradiction:
ImproveControl capabilityVSAvoidBattery life
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The control panel is presented periodically or on-demand based on user interaction rather than being continuously displayed. When a user hovers over a virtual element, the control panel appears temporarily to provide control options, and then disappears or becomes less prominent when not in use. This periodic presentation reduces the energy consumption associated with continuously rendering and processing control interface elements while maintaining full control capability when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control panel dynamically adjusts its visibility and responsiveness based on user proximity and interaction state. The interface transitions between different states (hidden, partially visible, fully visible) based on whether a user is hovering over or interacting with virtual elements, optimizing energy usage by only fully activating control functions when actually needed rather than maintaining a constant active state.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If traditional touch gestures are used to select icons, then precise selection is achieved, but multiple steps are required

Engineering Contradiction:
ImproveSelection accuracyVSAvoidSpeed of control
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

A hover detection mechanism serves as an intermediary between the user and the control interface. Instead of requiring direct touch interaction, the system detects the user's proximity through hover gestures and automatically presents relevant control panels. This intermediary layer maintains precise selection by detecting the user's intended target through proximity sensing, while simultaneously improving productivity by eliminating the need for users to manually navigate to and select control icons.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical touch-based selection system with a proximity-based hover detection system. Instead of requiring physical contact with the screen to select icons, the system uses capacitive or optical sensing to detect the user's finger proximity and automatically presents control options. This substitution maintains selection precision through accurate proximity detection while dramatically reducing the number of steps required, as users simply need to hover over the desired area rather than precisely tap individual icons.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Techniques are described herein that are capable of causing a control interface to be presented on a touch-enabled device based on a motion or absence thereof. A motion, such as a hover gesture, can be detected and the control interface presented in response to the detection. Alternatively, absence of a motion can be detected and the control interface presented in response to the detection. A hover gesture can occur without a user physically touching a touch screen of a touch-enabled device. Instead, the user's finger or fingers can be positioned at a spaced distance above the touch screen. The touch screen can detect that the user's fingers are proximate to the touch screen, such as through capacitive sensing. Additionally, finger movement can be detected while the fingers are hovering to expand the existing options for gesture input.
