Solution Overview

Problem

Conventional handheld devices lack the ability to determine whether they are being operated by the left hand or the right hand, leading to inadequate user interface configuration and impaired usability for both left-handed and right-handed users, resulting in increased costs due to the need for separate products for each handedness.

Innovation Solution

Implementing sensor-based user interface control using a combination of sensors such as accelerometers, gyroscopes, and magnetometers to detect the orientation and motion of the device, along with high-resolution touch screens and pressure sensors to determine handedness, allowing the device to adapt its interface accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate products are designed for left-handed and right-handed users, then usability for specific users is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:
Improveusability for left-handed or right-handed usersVSAvoidproduct variety and configuration options
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device incorporates multiple sensors (accelerometer, gyroscope, magnetometer, pressure sensors) that enable a single universal device to detect and adapt to different handedness patterns, eliminating the need for separate left-handed and right-handed versions while maintaining optimized usability for both user groups

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

Solution Approach 2:

The device dynamically adjusts its configuration based on real-time sensor data that detects handedness characteristics during use. The interface layout, button positions, and control schemes are automatically reconfigured based on whether the device is being operated by a left-handed or right-handed user, allowing the same physical device to adapt its functionality to different users

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If separate products are manufactured for different handedness groups, then user experience is improved, but manufacturing and distribution costs increase

Engineering Contradiction:
Improveuser experienceVSAvoidmanufacturing and distribution cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

A single manufacturing line produces universal devices equipped with sensors that can identify and adapt to different handedness patterns, eliminating the need for separate manufacturing processes, inventory management, and distribution channels for left-handed and right-handed versions while delivering personalized user experience

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

3Device complexity

If conventional devices do not determine handedness, then device complexity is reduced, but usability and user experience are impaired

Engineering Contradiction:
Improvesensor integration and processing capabilityVSAvoidusability and user experience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent replaces manual configuration methods with automated sensor-based detection systems. Instead of requiring users to manually configure the device for their handedness or relying on simple mechanical asymmetries, the system uses accelerometers, gyroscopes, magnetometers, and pressure sensors to automatically detect handedness patterns and reconfigure the interface accordingly

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

AI summary

Methods and devices for sensor-based user interface control are disclosed. In one embodiment, a method for determining a characteristic of handedness includes sensing a rotation of a mobile device, determining a direction of rotation based at least in part on accessing information indicative of a first position state prior to sensing the rotation and accessing information indicative of a second position state subsequent to sensing the rotation, and determining the characteristic of handedness based at least in part on the direction of rotation, the first position state, and the second position state. The characteristic of handedness includes one of a left handedness or right handedness. The method further includes determining a user interface mode based on the determined characteristic of handedness, and controlling the mobile device in accordance with the determined user interface mode.
