Solution Overview

Problem

Existing technologies do not provide an effective way to visually indicate a player's mental state during computer gaming, making it difficult for an audience to gain insight into the player's mental state.

Innovation Solution

A keyboard with a receiver for receiving electroencephalography (EEG) measurements, a light source, and a controller to control the light source based on the EEG data, providing a visual indication of the player's mental state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a keyboard integrates EEG receiver and light source to indicate player's mental state, then the audience can easily observe player's mental state during gaming, but the device complexity increases

Engineering Contradiction:
Improveplayer's mental state informationVSAvoidkeyboard device complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The keyboard integrates multiple functions including EEG signal reception, mental state processing, and visual indication through light sources. This multi-functional design allows the keyboard to serve both as an input device and as a mental state display device, resolving the contradiction by consolidating multiple functions into a single device rather than adding separate components for each function

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

Solution Approach 2:

The keyboard acts as an intermediary device between the player's brain (EEG sensor) and the audience's visual perception (light source). It receives neural signals, processes them into mental state information, and converts this into visual indicators that the audience can easily observe, thus mediating the information transfer without requiring direct brain-to-audience connection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the keyboard controls light source based on EEG data, then visual indication of mental state is provided, but energy consumption increases

Engineering Contradiction:
Improvemental state information transmissionVSAvoidkeyboard energy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The light source operates periodically rather than continuously, changing its state based on detected mental states. The system activates the light source only when mental state changes are detected or during relevant gaming moments, reducing overall energy consumption while maintaining effective communication of mental state information to the audience

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system changes the parameters of the light source (such as color, brightness, or pattern) to encode different mental states. By using parameter changes rather than continuous high-power operation, the system can convey rich information about mental states while controlling energy consumption through efficient parameter modulation

Inventive Principle:
Principle #35Parameter changes
