Solution Overview

Problem

Multi-touch surfaces in desktop environments face limitations due to sensing resolution issues and lack of tactile feedback, making precise interactions like typing on projected keyboards or selecting fine features difficult, and they often replace traditional input devices, reducing user comfort and precision.

Innovation Solution

A system that integrates multi-touch surfaces into a desktop environment alongside traditional keyboards and mice, allowing users to perform multi-touch operations in proximity to these devices, enhancing interaction bandwidth by defining regions on the multi-touch display for specific tools like enhanced task bars, multi-functional touch pads, and digital mouse pads, while maintaining the use of keyboards and mice for precision inputs.

VSEngineering Contradiction Analysis

1Productivity

If multi-touch surfaces replace traditional input devices, then interaction efficiency is improved, but measurement precision deteriorates

Engineering Contradiction:
Improveinteraction efficiencyVSAvoidtouch input precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent combines multi-touch surfaces with traditional input devices (keyboard and mouse) in a hybrid configuration. The multi-touch surface handles general interactions while the traditional keyboard and mouse remain available for precision tasks, merging the benefits of both input methods without forcing a complete replacement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates different interaction zones on the multi-touch surface with varying levels of precision and functionality. Certain regions are optimized for multi-touch gestures while maintaining compatibility with traditional input devices, allowing users to select the appropriate input method based on the specific task requirements.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If multi-touch surfaces replace traditional input devices, then ease of operation is improved, but reliability deteriorates

Engineering Contradiction:
Improveuser comfortVSAvoidinput accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system merges multi-touch surface operations with traditional keyboard and mouse input, allowing users to leverage the ease of multi-touch for navigation and control while relying on the reliability of traditional devices for precision-critical operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a software layer that mediates between the multi-touch surface and the operating system, translating touch gestures into reliable input commands while maintaining the option to use traditional input devices when higher reliability is needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If multi-touch surfaces are used for precision input, then device complexity is reduced, but manufacturing precision deteriorates

Engineering Contradiction:
Improveinput device configurationVSAvoidsensing resolution
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent combines the multi-touch surface with traditional keyboard and mouse devices, reducing the need for highly precise multi-touch sensing while maintaining precision input capabilities through the traditional devices. This hybrid approach lowers manufacturing precision requirements for the touch surface itself.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses the traditional keyboard and mouse as reference implementations for precision input, copying their proven reliability and precision characteristics into the hybrid system, thereby reducing the burden of achieving high precision through multi-touch sensing alone.

Inventive Principle:
Principle #26Copying

AI summary

A technique for integrating a multi-touch surface into a desktop environment is disclosed. One or more multi-touch display devices are placed on the horizontal surface surrounding or beneath a keyboard or mouse. At least one region on the multi-touch surface is defined to display one or more user interface tools on the multi-touch surface. The one or more user interface tools displayed via the multi-touch surface may control or display information associated with desktop applications displayed via a primary display device.
