Solution Overview

Problem

Existing user interface systems fail to adapt to situations where users are temporarily unable to use preferred input methods due to carrying objects, leading to inconvenience and inefficiency.

Innovation Solution

A user interface system that measures user characteristics using sensors, such as plantar sensors, to determine if hands are available for input, and if not, activates alternative input methods like voice or foot-based interfaces, ensuring continuous interaction with electronic devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hand-based user interfaces are used, then ease of operation is improved, but adaptability deteriorates when users are carrying objects

Engineering Contradiction:

Improveease of operationVSAvoidadaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically switches between different user interface modes (hand-based, voice-based, foot-based) based on real-time detection of user context. When objects are detected in the user's hand, the system transitions from hand-based UI to alternative input methods, making the interface adaptable to changing user conditions while maintaining ease of operation through automatic adaptation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the user interface by detecting physical states (presence of objects in hand) and adjusting the interface mode accordingly. This parameter change enables the system to switch between different input methods based on user context, resolving the contradiction between ease of operation and adaptability.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple user interfaces are provided, then adaptability is improved, but device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements multi-functionality by integrating multiple user interface types (hand-based, voice-based, foot-based) into a single unified system. The controller manages all interface types and automatically selects the appropriate one based on user context, providing adaptability without requiring separate independent systems, thus managing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs self-service by automatically detecting user context (presence of objects, user actions) and autonomously selecting the appropriate interface mode without user intervention. This automatic selection mechanism provides adaptability while minimizing the complexity burden on the user, as the system manages interface switching based on sensed conditions.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If automatic interface switching is implemented, then ease of operation is improved, but measurement precision requirements increase

Engineering Contradiction:

Improveease of operationVSAvoidmeasurement precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system uses partial measurement (detecting only the presence of objects in hand rather than complete user state analysis) to trigger interface switching. This partial action approach provides sufficient precision for effective interface selection without requiring overly complex or precise measurements, thus maintaining ease of operation while managing measurement precision requirements.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Technologies are generally described to provide alternate user interfaces based on user context. In some examples, a user interface system may measure a user characteristic associated with a particular user interface type. The user interface system may then determine whether the measured user characteristic is suitable for use as a user interface input, for example by comparison with a baseline user characteristic. Upon determination that the measured user characteristic is suitable, the user interface system may use the measured user characteristic for user interface purposes. On the other hand, upon determination that the measured user characteristic is not suitable, the user interface system may use a different user interface type to attempt to receive user inputs.
