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.
Therefore, we aim to develop an in-action system that converts sensor data into simple, motor-transferable information and displays it to jumpers via LEDs integrated into ski googles.

Detailed Task Description
The main goal of this thesis is to design, build and test an intelligent ski goggle that provides in-action feedback to athletes. Goggles should inform athletes about their center of gravity positioning druing the in-run. For this purpose, sensor data is collected from the insole of ski boots and processed with a tinyML model. The extracted feedback data is displayed over a LED display inside the glasses. According to the level of the student and the chosen thesis type (BT/ST) the work will include some or all following tasks:
Goals
Firmware Development
- Implement the BLE coded PHY stack on a nRF52 microcontroller (Nordic semiconductors) integrated in an existing multisensor system for ski-jumping
Characterization
Characterization of data transmission quality and identification of losses using BLE coded PHY in various laboratory scenarious:
- with increasing distance between source and target
- with high velocity differences between source and target.
- Using synthetic and/or real sensor data
Field Test
- Transfer of the measurment setup on a ski jumping hill.
- Validation of the system in a real-world scenario.
