AbleMouse Beyond Switch Edition

Product Introduction

1. Definition: AbleMouse Beyond Switch Edition is an open-source, micro-movement detection system categorized as assistive technology hardware/software. It translates minuscule physical signals (e.g., slight mouth opening) into full computer control.
2. Core Value Proposition: It provides digital independence for users with extreme paralysis where traditional assistive devices (eye-trackers, sip-and-puff systems) fail, using a single micro-movement input to navigate complex interfaces affordably.

Main Features

1. Micro-Signal Input Processing:
   • How it works: Receives input from any compatible sensor (EMG, pressure, capacitive) detecting minimal muscle twitches or movements.
   • Technology: Custom signal filtering algorithms ensure reliable detection of sub-millimeter movements, reducing false triggers.
2. Hierarchical Menu Navigation System:
   • How it works: Users navigate a deeply customizable radial or linear menu structure via timed selections or repeated micro-signals.
   • Technology: Python-based core with JSON configuration for menu depth, item order, and action mapping (mouse clicks, keyboard shortcuts, macros).
3. OS Language-Agnostic Voice Command Synthesis:
   • How it works: Generates synthetic voice commands (e.g., "Open Chrome," "Scroll down") internally, bypassing the operating system's speech recognition requirements.
   • Technology: Integrates with VB-CABLE virtual audio to inject commands directly into the OS sound input, enabling control for non-verbal users.

Problems Solved

1. Pain Point: Prohibitive cost and complexity of existing high-end assistive tech (e.g., $1,000+ eye-trackers, $300+ MouthPad) for users with total paralysis and minimal movement capability.
2. Target Audience: Individuals with Locked-In Syndrome (LIS), late-stage ALS, high-level spinal cord injuries (C1-C4), or severe cerebral palsy lacking reliable limb, head, or eye control.
3. Use Cases:
   • Operating communication software (e.g., AAC devices) using only a jaw tremor.
   • Controlling smart home devices via a single cheek muscle sensor.
   • Browsing the web independently when only a fingertip micro-twitch is possible.

Unique Advantages

1. Differentiation: Unlike MouthPad (requires tongue dexterity) or eye-trackers (require precise eye control and calibration), Beyond Switch works with any detectable micro-movement via adaptable sensors. It’s open-source (MIT license), enabling free customization vs. proprietary systems.
2. Key Innovation: The "single-switch hierarchical menu" architecture transforms one binary input signal into complex control through layered timing-based selection, eliminating the need for multiple switches or high-precision inputs.

Frequently Asked Questions (FAQ)

1. What sensors work with AbleMouse Beyond Switch?
   Any sensor outputting a digital on/off signal or analog voltage readable by its ESP32 microcontroller (e.g., EMG sensors, pressure pads, capacitive touch, sip-puff switches via ADC).
2. Can it work without internet access?
   Yes, the core system operates offline. Voice command synthesis requires local TTS engine installation but doesn’t need cloud connectivity.
3. Is coding knowledge needed to set up AbleMouse Beyond Switch?
   Basic configuration (menu setup, sensor calibration) uses JSON files and a GUI tool. Advanced customization requires Python skills, but pre-configured profiles are available.
4. Does it support macOS or Linux?
   Currently optimized for Windows. macOS/Unix support is experimental and requires community testing (see compatibility table).
5. How does it compare to Neuralink for paralysis?
   Beyond Switch is a non-invasive, affordable ($50-$150 DIY build), open-source solution available now, whereas Neuralink is invasive, experimental, and commercially unavailable.
