Wireless In Action Data Streaming in Ski Jumping (1 B/S)

Short Description
In ski jumping, low repetition rates of jumps limit effectiveness of training. Thus, increasing learning rate within every single jump is key to success. A critical element of athlete training is motor learning, which has been shown to be accelerated using feedback methods. Today, coach’s training feedback is mainly oral and based on recorded video data. Video data provides good insight into the entire jump, however translating video information into actual motor control is difficult
To improve current feedback methods, we want to develop an in-action system that converts sensor node data into simple yet motor-transferable information. To do this, data must be transmitted between onbody sensor nodes as well as between a sensor node master and the coaching tower. This requires reliable wireless communication with sufficient bandwidth and range.

Detailed Task Description
The main objective of this work is to implement and test a reliable Bluetooth Low Energy Coded PHY radio communication between an existing sensor node and a gateway. Field measurements (also with real ski jumpers) shall demonstrate the performance of the developed system. According to the level of the student and the chosen thesis type (BT/ST) the work will include some or all following tasks:
Goals
Sensors and Acquisition
- Investigation and evaluation of various commercially available sensor technologies (IMUs, pressure sensors).
- Evaluation of the attachment of sensors to skis and in boots.
- Use an in-house multipurpose embedded systems controller (Vitalcore) to build & test data collection with sensors.
Communication and Data Transfer
- Develop a data transfer strategy to
- collect data from two different sensors, and
- to transmit synchronized (raw) data to the coaching tower.
- Use an in-house multipurpose embedded systems controller (Vitalcore) to test data transfers via BLE.
- Test data transfer in ski jumping arena situation and revaluate transfer strategy if necessary.
Assembly and Test
- Make a PCB board design for the readout system.
- Design a casing to attach sensors system on the skis or shoes. Aiming for a minimalistic form-factor and weight.
- Test, build and evaluate a working prototype in laboratory conditions and in a real-life environment.
