DEADLINE EXTENDED! Apply now for early-stage funding through the Softeq Venture Studio. Application is now due by Saturday, June 3rd.
The client had a demo app that powered a puck-like device used in action sports. The solution showcased several features but didn’t work as a whole platform.
After the upgrade, the system would help athletes improve their technique and track progress.
The device with an in-built advanced compute module, 9-axis sensor, and GPS system can be mounted onto a gamut of sports equipment, including snowboard, surfboard, skateboard, BMX bike, wakeboard, basketball, and more. Paired with a specially developed app, the complete solution is set to enable professional and casual sports enthusiasts to improve their technical skills by tracking the trick-making progress.
Using radio or BLE frequency technology, the mobile app connects wirelessly to the sensor that works with accelerometers and gyroscopes providing for the following capabilities:
Recording a full HD video of the trick, while retrieving data from the sensor unit
Showing video preview with:
- Charts generated based on the data retrieved from the sensor unit
- Real-time speed parameters based on a customized speed calculation algorithm
- Real-time 3D spinning model
- Trick and move recognition
Exporting video into app, while adding an overlay of charts, patterns, and speed values
Supporting external cameras
When customizing the speed calculation algorithm, the team worked around the problem of processing big chunks of data retrieved from multiple sensor units using a complex filtering mechanism. The team also had to come up with solutions for overcoming the UWP technical limitations.
The solution was test-driven in a real-world environment by a pro surfer, who confirmed the viability of the system under development. The extended version of the demo app was showcased during a public presentation at a development conference organized by the customer.
