Neurotechnology

OPPORTUNITY

Neuroscientist, engineer, and TEDx speaker Dr. Greg Gage is on a quest to transform complicated neuroscience into practical learning experiences across the globe and with learners of all ages. In Backyard Brains, he and his team designs new hardware and software to capture and send neural signals in real-time so that it can be displayed on mobile devices.

Their Android application, Spike Recorder, however, failed to accommodate newer devices because of hardcoded device IDs and ageing APIs.
Moreover, the application was not compliant with the newest needs of Google Play Store. To extend to more systems and offer compliance, an upgrade was required in such a way that it did not interfere with the functionality already in place.

SOLUTION

BrainX delivered an optimized and future-proof neural signal processing by implementing:

• Dynamic Device ID Allocation:
  • Implemented UsbManager and UsbDevice APIs for USB Enumeration.
  • Introduced an enumeration system for multiple connected devices.
•  USB Communication Optimization:
  • Integrated FelHR85/UsbSerial (v6.1.0) for efficient serial communication.
  • Processed data asynchronously using USB Serial library’s read callbacks and background threads.
  • Improved bulk transfer handling and stabilized real-time data flow.
  • Maintained an Arduino-like text protocol for streamlined hardware interaction.
•  Android API Compliance Upgrade:
  • Transitioned from SDK 30 to SDK 33 to meet Play Store requirements.
  • Upgraded AndroidX libraries for improved stability and compatibility.
  • Integrated the latest Crashlytics for better app monitoring and debugging.
•  GitHub-Based Open-Source Maintenance:
  • Implemented an organized branching strategy to enable smooth code integration.
  • Enabled peer-reviewed pull requests and maintained technical documentation.
•  Automated Testing & Validation:
  • Integrated unit testing for device connection stability.
  • Conducted regression testing to ensure feature compatibility.

Healthcare

OPPORTUNITY

The Gyroscope team partnered with BrainX to address the challenge of maintaining consistent head positioning during dental procedures. The client sought a comprehensive solution for precise head orientation tracking. They also required facial movement monitoring to provide real-time, accurate positioning data.

The goal was to reduce manual intervention, improve procedural outcomes, and enhance patient experience through advanced sensor integration and visual tracking. BrainX developed a native Android app integrating dual 9-axis gyroscope sensors and camera-based facial recognition. It leverages Visage SDK technology for precise and efficient facial tracking.

Healthcare

SOLUTION

The Gyroscope Dental App equips essential features for streamlined face alignment and data management, including:

• Dual Sensor Setup: A user-friendly connection and calibration process for face and head sensors with real-time status indicators.
• Patient Data Entry: Simple, efficient data input with a seamless transition to sensor calibration.
• Real-Time Monitoring: Displays live sensor data with 3D facial tracking for real-time head positioning.
• Session Review & Sharing: Enables users to review, save, and share recorded sessions that enhance collaboration.
• Custom Camera Setup: Complements the real-time monitoring feature, delivering a seamless and engaging user experience.
