Solution Overview

Problem

Conventional wearable devices are difficult for users to conveniently manipulate due to their small size, limiting user interaction and efficiency in accessing information and functions.

Innovation Solution

A wearable device equipped with sensors that detect movement and gestures in the periphery, allowing users to shift focus and navigate through menus by measuring angles and directions, enabling intuitive interaction through peripheral object detection and gesture recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the wearable device is made small-sized, then it can be worn on the user's body, but it becomes difficult for the user to conveniently manipulate the device

Engineering Contradiction:
Improvedevice sizeVSAvoidmanipulation convenience
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent transitions from traditional 2D touch screen interaction to 3D spatial gesture recognition. Sensors detect the position and movement of objects (such as fingers) in three-dimensional space around the wearable device, enabling users to interact with the device through gestures in the surrounding space rather than requiring direct contact with the small device surface.

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

Solution Approach 2:

The patent introduces an intermediary interaction mode between the user and the wearable device. Instead of directly touching the small device, users perform gestures in the air or with objects near the device, and sensors detect these gestures to translate them into device commands. This intermediary gesture layer solves the manipulation difficulty while maintaining device compactness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If the wearable device is made small-sized, then it can be worn on the user's body, but the user interaction efficiency is limited

Engineering Contradiction:
Improvedevice sizeVSAvoiduser interaction efficiency
Core Design Contradiction:
Volume of moving objectVSProductivity

Solution Approach 1:

By utilizing three-dimensional gesture recognition, the system enables more expressive and efficient interaction commands compared to limited 2D touch gestures. Users can perform complex operations through simple spatial gestures, significantly improving interaction efficiency without increasing device size.

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

Solution Approach 2:

The patent replaces traditional mechanical touch input with sensor-based gesture detection. Instead of requiring physical contact with buttons or touch screens, the system uses sensors (such as cameras, accelerometers, or other detection devices) to recognize gestures in three-dimensional space, enabling faster and more efficient user interaction.

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