Motion Sensor Analysis (Mobile App) Title: Mobile Developer: Sensor Fusion & Signal Processing for Gait & Balance Analysis. Project Overview: We are looking for a Mobile Developer specialized in signal processing to develop digital balance and gait assessment tests (specifically the Digital Fukuda Stepping Test) for a vertigo-related smartphone application. Connection to Vertigo: Vertigo impairs balance and orientation. By recording body deviation and rotation during specific tests, we provide clinicians with critical data on vestibular health. Key Responsibilities: 1. Mobile Sensor Fusion: Capture real-time data from the smartphone's gyroscope and accelerometer while the device is worn by the user. 2. Digital Fukuda Test: Implement an algorithm to calculate the precise Angle of Rotation (Yaw) and displacement during "stepping in place" exercises. 3. Drift Compensation: Use Kalman or Mahony filters to eliminate sensor noise and ensure medical-grade accuracy. MANDATORY REQUIREMENTS - READ BEFORE BIDDING: • Work Samples Required: You must provide evidence of previous projects involving Mobile Sensors (IMU data) and Signal Processing. Samples of gait analysis, motion tracking, or orientation algorithms are required. • Mathematical Background: Deep understanding of sensor drift and filtering is essential. • Generic Bids: Applications without specific examples of sensor-based motion tracking will be discarded.
