Solution Overview

Problem

Current electronic computing devices lack an intuitive stylus-based user interface for switching tools or customizing settings within applications, such as changing font styles or tools, which requires cumbersome actions and lacks discreet interaction methods.

Innovation Solution

The implementation of a stylus-based touch-sensitive control feature that allows for various actions like swiping, tapping, or holding on a stylus detection surface to perform functions like adjusting variables, switching tools, or launching applications, without requiring direct contact, using technologies like capacitive or electrophoretic touch sensors, and providing animation, sound, or haptic feedback for user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If direct contact with the screen is used for UI control, then the user interface is simple and direct, but it distracts the user and lacks discreet interaction

Engineering Contradiction:

Improveuser interactionVSAvoiduser distraction

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a stylus as an intermediary tool between the user and the touch screen. The stylus includes a touch-sensitive control feature that detects touch actions (swipes, taps, holds) and transmits these actions to the computing device without requiring direct finger contact with the screen. This mediator approach enables discreet interaction while maintaining ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the interaction system into distinct components: the stylus with its touch-sensitive control feature, the detection circuitry, and the computing device. This segmentation allows the touch-sensitive control feature to be located away from the screen, enabling users to perform UI controls discreetly without their hand or finger obscuring the display.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If more control features are added to the stylus, then the functionality and versatility improve, but the device complexity increases

Engineering Contradiction:

Improvestylus functionalityVSAvoidstylus structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal touch-sensitive control feature on the stylus that can perform multiple functions depending on the detected touch action. The same physical feature can detect swipes, taps, holds, and other gestures, providing versatile functionality without requiring separate physical controls for each function. This multi-functionality approach increases adaptability while minimizing structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If touch-sensitive control feature is added to the stylus, then discreet interaction is enabled, but the manufacturing complexity increases

Engineering Contradiction:

Improvediscreet interactionVSAvoidstylus production

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent replaces complex mechanical control features (buttons, switches, dials) with a touch-sensitive control feature that detects electrical signals from user contact. This substitution simplifies the manufacturing process by using standard touch-sensing technology rather than requiring precision mechanical components, while still enabling discreet interaction capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Techniques are disclosed for interacting with a computing device using a stylus. The stylus is configured with a touch-sensitive control feature that can be activated to perform various actions while the stylus is touching or otherwise sufficiently proximate to a stylus detection surface of the device. The swipe function can be associated with a variety of tasks on the computing device such as: adjusting variables, executing a particular command, switching between tools, modifying a particular tool's settings, and launching an application. In some embodiments, the stylus-based touch-sensitive control feature is configured to allow for both forward and backward swiping actions, tapping actions, and various combinations of such touch-types on the touch-sensitive control feature to uniquely identify a corresponding function to be carried out on the computing device.
