Gesture Identification System for Mobile Data Entry

Solution Overview

Problem

The small size of mobile device keyboards and displays hinders accurate and quick data entry, leading to typing errors and processing delays in financial transactions, causing consumer frustration.

Innovation Solution

A gesture identification system that processes finger motions captured by sensors, such as cameras or motion sensors, to convert finger gestures into device inputs, allowing users to input data without physically interacting with the device, thereby enhancing data entry efficiency and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional keyboard is used on a mobile device, then data entry can be performed, but the small size of the keyboard and display hinders accurate and quick data entry

Engineering Contradiction:

Improvedata entry speedVSAvoidtyping accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical keyboard system with an optical gesture recognition system. Sensors (cameras, motion sensors) detect finger motions in three-dimensional space and convert them into device inputs, eliminating the need for physical keyboard interaction and enabling more accurate and efficient data entry through natural hand gestures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces three-dimensional spatial gestures as an additional dimension for data input. Instead of being constrained to a two-dimensional keyboard surface, users can perform gestures in three-dimensional space, which are then mapped to keyboard inputs, thereby improving both speed and accuracy of data entry.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a small keyboard is used on a mobile device, then the device remains portable, but typing errors increase and processing delays occur

Engineering Contradiction:

Improvedevice portabilityVSAvoidtransaction processing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical keyboard system with an optical gesture recognition system. Sensors (cameras, motion sensors) detect finger motions in three-dimensional space and convert them into device inputs, eliminating the need for physical keyboard interaction and enabling more accurate and efficient data entry through natural hand gestures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If conventional typing methods are used on a mobile device, then information can be entered, but user frustration increases due to errors and delays

Engineering Contradiction:

Improveinformation entry capabilityVSAvoiduser frustration

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical keyboard system with an optical gesture recognition system. Sensors (cameras, motion sensors) detect finger motions in three-dimensional space and convert them into device inputs, eliminating the need for physical keyboard interaction and enabling more accurate and efficient data entry through natural hand gestures.

Inventive Principle:

AI summary

Various methods and systems are provided to allow a user to perform finger gesture motions, such as making typing, swiping, tapping, or other types of finger motions to provide device input, such as typing, clicking, or selecting data into a webpage, application, operating system, or toolbar, that was normally performed by the user having to use a keyboard, mouse, stylus, microphone, touchscreen, or another input device.
