Solution Overview

Problem

Current user interfaces, particularly those based on two-dimensional sensing, lack intuitive and efficient methods for scrolling and interacting with lists, as they do not provide natural gestures-based feedback, limiting user experience and interaction efficiency.

Innovation Solution

A three-dimensional user interface system that utilizes a depth sensor to detect hand gestures, allowing users to scroll and zoom lists by performing swipe gestures, with the system providing friction-like feedback and adjusting list size based on scrolling speed, enhancing readability and interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional two-dimensional sensing interfaces are used for scrolling, then device complexity is reduced, but ease of operation and interaction efficiency deteriorate due to lack of intuitive gestures

Engineering Contradiction:
Improvegesture-based interactionVSAvoidsensing system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent transitions from two-dimensional touch sensing to three-dimensional depth sensing, adding a new dimension to the interaction space. This enables natural hand gestures in mid-air to be detected and translated into scrolling actions, significantly improving ease of operation while the added complexity is managed through software processing of depth data

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If scrolling speed is increased for efficiency, then productivity improves, but readability deteriorates due to motion blur and reduced visual processing time

Engineering Contradiction:
Improvescrolling speedVSAvoidreadability
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent dynamically adjusts list presentation characteristics based on detected scrolling speed. When fast scrolling is detected, the system modifies rendering to maintain readability, potentially by reducing visual clutter or adjusting item presentation, thus maintaining both high productivity and information retention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides friction-like visual feedback that adapts to scrolling speed, giving users tactile-like cues about their interaction intensity. This feedback mechanism helps users modulate their scrolling speed to maintain optimal readability while achieving desired productivity levels

Inventive Principle:
Principle #23Feedback

3Ease of operation

If friction-like feedback is provided to simulate tactile experience, then ease of operation improves, but use of energy increases due to continuous visual processing and feedback generation

Engineering Contradiction:
Improvetactile feedback simulationVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent replaces physical mechanical feedback mechanisms with visual feedback generated on the display. By using optical/electronic visual cues instead of mechanical tactile components, the system achieves tactile-like interaction experience with significantly lower energy consumption and no moving parts

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

AI summary

A method, including presenting, by a computer, a scrollable list of interactive items on a display driven by the computer, and receiving an input from a user of the computer. The list is scrolled at a speed indicated by the input, and the list is zoomed in response to the speed of the scrolling.
