About AI Training and Human Motion Data

AI and robotics systems learn from carefully collected examples. Human contributors record, review, and organize real-world data so models can better understand movement, environments, and physical activity. This work is part of the growing human side of building modern AI.

• Contribute data used in AI and robotics training
• Work remotely with a smartphone and approved recording equipment
• No previous AI training experience is required

The Role

OpenTrain is hiring Smartphone Motion Data Video Recorders to support Human Motion Data Capture. You will collect synchronized first-person video and smartphone inertial measurement unit, or IMU, motion data while completing specified physical activities.

The role is designed for careful, reliable data collectors who can follow detailed technical instructions and maintain consistent quality. Work is part-time, contract-based, and requires less than 20 hours per week.

• Pay: $6 USD per hour
• Employment type: Part-time contractor
• Experience level: Entry level
• Subject matter: Human Motion Data Capture
• Working language: English

What You'll Do

You will use a compatible smartphone and head strap to capture video from a first-person perspective while keeping both hands visible. You will also collect smartphone IMU data during the assigned activities and protect the integrity of the video and sensor information.

The work requires consistent execution of repetitive physical movements, careful documentation, and clear communication with the project team about observations or questions.

• Capture accurate smartphone IMU motion data during specified physical activities
• Record synchronized first-person video using a head strap
• Capture footage that includes both hands
• Follow technical protocols for quality, labeling, and standardization
• Deliver collected data consistently and on time
• Document observations and communicate questions clearly

Requirements

You must have access to a compatible smartphone and a suitable head strap. Strong attention to detail, reliable data collection habits, and the ability to follow standardized protocols are essential.

You should be comfortable using mobile devices for video and sensor-data capture, managing remote contractor tasks, documenting observations, and safely performing repetitive physical movements.

• iPhone 12 or newer, Google Pixel 6 or newer, or Samsung Galaxy S21 or newer
• Suitable head strap for first-person video recording
• Ability to follow standardized motion-data collection and quality protocols
• Strong attention to detail and consistent quality practices
• Clear written and verbal communication
• Ability to perform repetitive physical movements safely and consistently

Helpful Background

Previous AI training experience is not required. Background knowledge or experience in robotics, kinesiology, human-motion analysis, sensor data collection, activity segmentation, or machine-learning dataset labeling can be helpful.

• Robotics experience or education
• Kinesiology or human-motion analysis knowledge
• Sensor data collection experience
• Familiarity with activity segmentation
• Machine-learning dataset labeling experience
