Dos Juegos is an analysis and study of sports performance in contact sports from a different perspective

What is it for?
This project is targeted to amateur teams or anyone who plays basketball as a hobby and wants to improve their game. The goal is to win the match by changing the way we see the game. Analyzing the possibilities of each player encourages their most outstanding qualities to achieve the best performance of the team.


Individually, it allows you to see how the intervention of each player affects the game, giving the opportunity to deepen the behaviours and patterns of the players.

Jointly, it allows you to identify what plays have been better and which ones are worse in order to learn and improve the game.

Context
In the last few years, technical developments have resulted in a high degree of reliability in the physical tracking of sports events. As a result, there is now a way to collect statistical and analytical data in real time.

In basketball’s case, since 2010, the NBA has adopted these technologies with the software SportVU, which uses wide angle lenses. The idea consists in distributing the cameras all over the field, recording the images from different angles to later track the positions of each player and the position of the ball.

Basketball is a very dynamic and active sport. This poses a difficulty for the players, who don’t have an objective and collective vision of how the game is being played. The game is very dynamic because the ball possessions are limited to 24 seconds. Therefore, on average, 150 plays per game. Registering the data generates an objective and irrefutable vision based on real facts with a high degree of reliability.

Process
After a thorough investigation, the project started to make sense after seeing one of the works by Espada y Santa Cruz for Corona Perspectives. Corona Perspectives consists of tracking the trajectory of a tennis ball in a match with the objective of developing an identity of the event. Thus, it becomes easier to identify how to represent the movement of a body. From there, after various tests and research about representations, mapping, tracking and SportUV, Dos Juegos proposes a mockup made with needles and thread in which the expected result of the tracking of the players in a basketball game was represented.

Once the ideas were laid down, it was decided to make the graphic representation of the result of a basketball game through a digital infographic. The infographic makes it easier to understand the complex information in an attractive visual way without losing the attention of the spectator. Recording a women’s senior basketball match by distributing different types of cameras through different places in the field: two Canon 7D, one Canon 5D, one camera 550D and a GoPro2. This match was the one used to analyze and study for Dos Juegos.

With the recordings, we obtained the tracking of the player’s trajectories and analytical data, as well as the total number of shots thrown and the successful shots. The physical performance was acquired with the technology monitored by the Fitbit bracelets. The gathered data are:

The trajectory of the players of the two teams, scores and percentage of successful shots.

The trajectories of the two teams compared by time, score and percentage of shots thrown and successful shots.

The trajectory of the individual players.

The comparative trajectories of two players in different positions, forward and centre, activity performance; distance, steps, burned calories and playing time.

Percentages of steps taken between the members of the same team.
