Thought-Controlled Device Using Line Patterns for Complex Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thought-controlled devices face challenges in accurately and reliably interpreting brain wave patterns for non-directional actions, leading to inefficiencies and inaccuracies in controlling non-tactile devices.
Innovation Solution
The use of patterns or line patterns and directional or movement intentions, or templates, which correspond to a user's thought, for the execution of actions, including thought-to-speech, thought-to-control, and thought-to-direction, allowing for more complex and accurate device control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one-to-one correlation of imagined directions with simple movements is used, then device control is simplified, but the range of controllable actions and directions is limited
Solution Approach 1:
The patent segments the control space by introducing line patterns as distinct from simple directional movements. Line patterns represent a new category of input that can define complex actions and directions, thereby expanding the range of controllable actions while maintaining the simplicity of one-to-one correlation for each pattern type.
Solution Approach 2:
The patent adds a new dimension to the control interface by introducing line patterns as a visual/spatial representation of thoughts. This dimensional addition allows users to express complex actions and directions that go beyond simple up/down/left/right movements, thereby increasing versatility without complicating the basic control mechanism.
2Ease of operation
If one-to-one correlation of brain wave patterns to actions is used, then device control is simplified, but accuracy and reliability of interpretation is reduced
Solution Approach 1:
The patent introduces line patterns as an intermediary representation between raw brain wave patterns and final actions. This intermediary layer allows for more accurate interpretation by providing a structured framework that maps complex brain wave patterns to specific line pattern categories, thereby improving measurement precision while maintaining operational simplicity.
Solution Approach 2:
The patent changes the parameter space for brain wave interpretation by introducing line pattern categories as a new classification system. This parameter change allows for more accurate and reliable interpretation of brain wave patterns by organizing them into distinct line pattern types, thereby improving precision without complicating the control interface.
3Ease of operation
If only simple directional thoughts (up, down, left, right) are used, then user input is simplified, but the precision and range of thought-controlled interactions is limited
Solution Approach 1:
The patent segments user input into two main categories: simple directional thoughts and line pattern thoughts. This segmentation allows users to maintain simple input for basic movements while using line patterns for precise control of complex actions, thereby achieving high precision without sacrificing ease of operation for common tasks.
Solution Approach 2:
The patent adds a visual/spatial dimension to user input by introducing line patterns that represent complex actions and directions. This dimensional addition enables precise thought-controlled interactions for complex tasks while keeping simple directional inputs unchanged, thereby maintaining ease of operation for basic controls while achieving high precision for advanced interactions.

AI summary
A system and method for controlling a non-tactile device including a receiving device configured to receive signals corresponding to a user's brain waves or movements, the brain waves or movements corresponding to a series of directional intentions, the intentions defining at least one line pattern, a processor configured to process the at least one line pattern, each of said at least one line patterns associated with an action of the device, and output a control signal to the non-tactile device related to the action.
