Solution Overview

Problem

Current methods for enabling or unlocking computing devices, such as smartphones, require manual interaction, which can be impractical for users who cannot use their hands or need to perform other tasks simultaneously, like soldiers in combat.

Innovation Solution

A method using an electroencephalograph (EEG) device to detect brain signals and optic nerve signals, allowing users to activate or unlock devices by observing flashing indicators or regions on a display, enabling hands-free operation through EEG data matching recorded patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual interaction methods (touch screens, keyboards, mice) are used to enable or unlock displays, then the device can be controlled, but users with physical limitations or those performing manual operations cannot operate the device

Engineering Contradiction:
Improvehands-free operation capabilityVSAvoidusability for users with physical limitations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical hand-based interaction (touch screens, keyboards, mice) with a neurological control system that detects brain signals via EEG to control device operations. The EEG device captures electrical activity from the user's scalp, and the processor interprets these signals to execute commands such as enabling displays or unlocking devices, completely eliminating the need for manual physical interaction.

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

Solution Approach 2:

The patent introduces an EEG device and signal processing system as an intermediary between the user's neurological system and the computing device. This intermediary captures brain signals, processes them through algorithms that identify specific patterns corresponding to user intent, and translates them into device control commands, enabling communication between the user's mental state and the device without physical contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If EEG-based hands-free control is implemented, then users with physical limitations can operate the device, but the device complexity increases

Engineering Contradiction:
Improvehands-free operation capabilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the computing device universally controllable through multiple input modalities. The device can be operated through traditional manual methods (touch screens, keyboards) or through EEG-based neurological control, allowing it to serve users with varying physical capabilities. This multi-functionality ensures the device adapts to different user needs without requiring separate specialized systems.

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

Solution Approach 2:

The system includes automatic signal processing and interpretation capabilities that enable the device to self-configure and respond to EEG patterns without requiring complex external processing equipment. The processor automatically identifies relevant brain signal patterns and executes corresponding commands, reducing the need for additional external devices or complex manual configuration procedures.

Inventive Principle:
Principle #25Self-service

AI summary

A method for activating an operational mode change of a device. The method includes flashing at least one indicator, wherein each of the at least one indicator flashes at a particular initial frequency. The method also includes receiving electroencephalograph (EEG) data from an EEG device of a user. The method further includes recognizing a portion of the received EEG data to substantially match activation EEG data, wherein the activation EEG data corresponds to predicted or recorded EEG data of the user in observance of one of the at least one indicator flashing at the particular initial frequency. The method additionally includes activating an operational mode change for providing power to a display upon recognizing the portion of the received EEG data to substantially match the activation EEG data.
