Solution Overview

Problem

Current human-computer interaction tools, such as touchpads and mousepads, occupy valuable space on computer desks, especially for graphical designers and gamers who require both touch/stylus and mouse functionality.

Innovation Solution

A touchpad or digitizer stylus pad designed to double as a mousepad, allowing a computer mouse to be used on its surface, with automatic disabling of touch/stylus or mouse functions based on priority settings, enabling a single device to serve both purposes without the need for multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a touchpad or digitizer stylus pad is used for touch and stylus input, then precise touch control is achieved, but desk space is occupied

Engineering Contradiction:
Improvetouch control precisionVSAvoiddesk space
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The input surface is designed to serve dual purposes: it functions as a touchpad for finger-based touch input and as a mousepad for optical mouse tracking. The system automatically detects which device is being used and switches modes accordingly, allowing one surface to replace two separate input devices, thereby reducing desk space while maintaining precise control capabilities

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

2Ease of operation

If a computer mouse is used with a mousepad, then smooth pointer control is achieved, but desk space is occupied

Engineering Contradiction:
Improvepointer control smoothnessVSAvoiddesk space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The input surface provides a unified platform that supports both optical mouse tracking and touchpad functionality. When a mouse is detected, the surface acts as a mousepad enabling smooth pointer control; when no mouse is present, it automatically switches to touchpad mode, eliminating the need for a separate mousepad and reducing overall desk space requirements

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

3Adaptability or versatility

If separate touchpad and mousepad devices are used, then both input methods are available, but device complexity increases

Engineering Contradiction:
Improveinput method availabilityVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the functions of a touchpad and a mousepad into a single integrated input surface. The system includes detection circuitry that identifies whether a mouse or finger touch is being used and automatically switches between modes, providing both input methods through one device rather than requiring two separate devices, thus reducing system complexity

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If automatic device switching is implemented, then seamless operation is achieved, but processing time is increased

Engineering Contradiction:
Improveoperation seamlessnessVSAvoiddevice switching time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system continuously monitors the input surface for the presence of a mouse or touch input in advance, maintaining detection circuits in a ready state. This preliminary detection allows the system to automatically switch between mousepad and touchpad modes instantly when a device is introduced or removed, ensuring seamless operation without noticeable delays or interruptions in control

Inventive Principle:
Principle #10Preliminary action

AI summary

A design that allows a touchpad or a digitizer stylus pad to double up as a mouse mat/pad so that a computer mouse can be used over it is provided. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for managing input devices are provided. The apparatus may determine whether a surface input is received at an input surface. The apparatus may determine whether a mouse input is received at a computer mouse. The apparatus may disable one of the input surface and the computer mouse that has a lower priority than another of the input surface and the computer mouse when the surface input and the mouse input are received at respective input device within a threshold window of time.
