Bachelor Thesis: Tracking Tracing Training
Student: Thomas Mayer
The basic idea of my bachelor thesis was to track the ping pong ball in realtime to create data visualisations for trainers and players. After a few weeks of working I started developing a projected mapped interface for the ping pong table to show the collected data. By projecting game obstacles on the surface I figured out that I can change the game play totally.
With 230 km/h table tennis balls are the fastest balls within balls sports
the dashboard animations shows the calendar function, the settings and the highscore panel.
This here is the dashboard for a single player. All important information for players are collected in different panels. There is an abstract documentation and calendar function, a collection of personal high scores and many more facts to review the performance and the development of the player.
It was challenging to design a functional interface which is projectable on a ping pong table taking in consideration the players’ ergonomics. Project resolution, layout of the interface and arrangement of buttons were the biggest problems that I had to test in many prototypes.
In my office I set up a ping pong table surrounded by technical equipment. After several tests I installed two Playstation CL-eye cameras and a full HD projector to work on the tracking of the pin ping ball and processing of the collected data. The development and testing on the ping pong table was very important. The first running prototype enabled me to include players in my testing to ensure a user orientated development. This was significant from the beginning of the project until the end. There were many ideas and visualisations I developed but after a few seconds of testing they failed. The hole project was developed in VVVV.
The Prototype was fully functional at the exhibition and run over several hours. It was fun to show my work to visitors of the Exhibition and also gave me a few more insights of what others see and expect.
this is the incedrible soundtrack of the table tennis trainer video, i highly recommend it.
