Solution Overview

Problem

Conventional computer mice require a large movement area for precise cursor positioning, especially with large translation ratios, making precise motor coordination necessary, which can be cumbersome and difficult to manage.

Innovation Solution

A computer mouse with a housing and movement detector for X/Y axis movements, combined with a hand detector for position and gesture recognition, allowing touchless input operations and intuitive cursor control, including gesture-based selection and menu access, with optional integration of electric field detection and optical feedback for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a large movement area is used for precise cursor positioning, then positioning precision is improved, but the device complexity and space requirements increase

Engineering Contradiction:
Improvecursor positioning precisionVSAvoidmovement area on underlay
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent introduces a new dimension for input by detecting hand gestures and positions in three-dimensional space above the mouse surface. The hand detector captures Z-axis information (height above surface) and spatial hand positions, allowing cursor control without lateral movement on the underlay surface. This vertical dimension replaces the traditional horizontal movement plane.

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

Solution Approach 2:

The patent replaces the mechanical movement-based control system with a sensor-based detection system. Instead of requiring physical movement of the mouse across the surface to generate cursor movement, the system uses optical or capacitive sensors to detect hand gestures, finger positions, and movements in the air above the mouse, converting these into cursor control signals.

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

2Measurement precision

If a large movement area is used for precise cursor positioning, then positioning precision is improved, but ease of operation deteriorates due to demanding motor coordination

Engineering Contradiction:
Improvecursor positioning precisionVSAvoidmotor coordination demand
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the mechanical movement-based control system with a sensor-based detection system. Instead of requiring physical movement of the mouse across the surface to generate cursor movement, the system uses optical or capacitive sensors to detect hand gestures, finger positions, and movements in the air above the mouse, converting these into cursor control signals.

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

Solution Approach 2:

The patent changes the input parameters from lateral mouse displacement (X-Y plane movement) to hand gesture parameters (finger position, hand orientation, vertical distance from surface). The system interprets gestures such as finger lifting, hand tilting, and circular motions in the air to control cursor movement, fundamentally changing how input parameters are captured and processed.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If touchless gesture detection is added to the mouse, then ease of operation is improved, but device complexity and energy consumption increase

Engineering Contradiction:
Improveintuitive input capabilityVSAvoiddetector system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into a single device by combining the traditional movement detector with a hand detector capable of gesture recognition, position detection, and touch sensing. The unified detector system serves multiple purposes: tracking mouse movement, detecting hand presence, recognizing gestures, and measuring pressure, eliminating the need for separate devices.

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

Solution Approach 2:

The patent introduces an intermediary evaluation unit that processes signals from the hand detector and translates gestures into meaningful control commands. This intermediary layer interprets raw sensor data (such as changes in capacitance or optical patterns) and converts them into standardized input signals that the computer system can understand and execute.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If touchless gesture detection is added to the mouse, then ease of operation is improved, but energy consumption increases

Engineering Contradiction:
Improveintuitive input capabilityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic or event-driven sampling of hand gestures rather than continuous monitoring. The hand detector activates or increases sampling rate only when hand presence is detected or when gestures are occurring, reducing energy consumption during periods of inactivity while maintaining responsive gesture recognition capability.

Inventive Principle:
Principle #19Periodic action

AI summary

The invention refers to an input device for computer system. The invention is based on the task of creating solutions to make it possible to considerably simplify mouse-based input operations in the use of computers. This task is solved in accordance with the invention by a computer mouse with a housing and a movement detector to generate control data which as such correlate with the movement of the housing along the X or Y axis, and a hand detector to generate control data which as such correlate with the position and/or the finger gestures of a hand in relation to the housing before the computer mouse is touched. This makes it advantageously possible to carry out input operations to an even better degree with a computer mouse, in particular cursor controls, in a way that can be intuitively and easily mastered.
