Go from Cue Noob to Pool Shark with Projector Technology

Being an expert in video pool games does not actually mean that you will end up playing like a professional on a real professional pool table. Pool is a simple yet complex game. You need to be aware of all the possible angles, a little bit of physics, lots of cognition, and great hand-eye co-ordination. However, after the development of PoolLiveAid all that is now a thing of the past.

Technology for Pool Players

PoolLiveAid is a project developed by Ricardo Alves, Luis Sousa, and J.M.F Rodrigues from the University of the Algarve, in Portugal. It is a kind of a ‘digital cheat code’ which allows pool players to make even the most difficult shots, and to sink balls without working up a sweat.


PoolLiveAid utilizes a projector which hangs above the pool table and offers real-time shot making guidance. The projector shines a light onto the pool table which shows the path of the ball in relation to the angle of the cue. The system takes into consideration the location of the cue ball, the borders of the pool table, and the angle of the pool cue to make up all kinds of possible calculations that a professional pool shark would make in his/her mind. Such calculations are made in real time. Thus, just like in pool video games, the line indicating the path of the cue ball will change real time as you move the cue in different directions.

Improving Your Odds

The developers of the project have clarified that they created an algorithm which analyzes and tracks the position of the ball. It then detects lines that match up to the angle of the cue. A computer is connected to the projector which gets updated instantly. This is what results in the real time live calculations of pool shots.

Some Holes

It may however be noted that the system has a few shortcomings. It cannot detect the speed and the spin on the cue ball. Thus, if you hit the cue ball right at the bottom, then it is most likely to go flying out of the table and not follow the lines projected by the overhead system. It also cannot predict the outcome of complex shots which involve many different balls at the same time. However, there is no doubt that this project is a blessing for novice cue holders. PoolLiveAid definitely does away with guesswork about the cue trajectory and other angle visualizations.
