Somatosensory tracking-NBA big data era

For NBA fans, every move in the NBA can mobilize all of their enthusiasm. Recently, according to technology blog Mashable.com, the U.S. NBA and Stats LLC jointly announced a few days ago that they will install somatosensory tracking technology in all the stadiums from 2013 to 2014. What is going on with this cooperation? Somatosensory track again in what role, which means for the fans in the end, take a look at the following translation:

Stats SportVU player tracking system includes 6 cameras and specialized software. The system will be installed at 30 NBA teams' stadiums to record and track basketball and player movements. This system will provide continuous data flow and innovative statistics, including speed, distance, inter-player spacing, and ball handling, to achieve more targeted analytics.

In addition to NBA TV, NBA.com and the NBA Game Time app will also provide data from SportVU. Steve Helms, executive vice president of operations and technology at NBA, said: "We are a data-driven coalition and the expanded collaboration between us and Stats will give teams and fans more groundbreaking data. The new era of statistics, SportVU is an invaluable resource for basketball players and passionate fans. "

Stats CEO Gary Vollras said: "The new NBA terms will include the speed file, the type of offensive tactics, defensive position and stadium coverage and so on."

Some people may still think that the NBA is just a player's personal performance, but this movement tracking technology may make them have different views. If LeBron James made GIF animations on every attack in Game 7 of last year's Finals, the system realized its value.

NBA has long been the expert in data statistics

According to "Economic Observer," the relevant reports, from the 1980s, NBA began to use data management technology, all players score, rebounding, assists, blocks, steals, errors, foul and a series of field data are counted in the column. NBA detailed and detailed statistics, not only can provide a single player inquiries, but also can compare two players, including two people when the offensive and defensive performance, such as James averaged 28 points, Kobe Bryant was 27 points, but when When the two met, Bryant averaged 30 points, James only 24 points.

NBA data statistics and management has been nearly 30 years of accumulation and improvement. This is the precious wealth of the NBA and the teams.

How does it serve the team?

For example: Statistics show that when James dribbled the left side of the basket, he chose to shoot more. When he was on the right side of the basket, the offensive mode was mainly to make breakthrough layups. This statistic told the defender that when James was on the left side of the rim, he could choose to put him in tight fit to seal him, as he would not break through from the left; and when James came to the right of the rim , Then you can not close the body, so easy to be left behind him step by step, then a good defender will choose to stay away from James two steps, because he will not choose jumper, without leaving a choice of cover, empty enough The distance, but can prevent him from breaking.

Almost every player, there are related data can break the advantages and limitations. For another example, NBA statistics Yao Ming dribble dribble in the basket more than the number of mistakes concluded that Yao Ming, the right hand catch the ball can usually dribble three times, the left hand can only dribble the ball twice. This statistic tells the defender that in order to disarm Yao's threat to the basket, he should be restricted to the area away from the basket so that he must dribble more than three times to get to the basket so he often fails.

According to the Economic Observer, 15 of the 30 NBA teams have hired at least one team data analyst, who typically make important recommendations on match days, draft picks and trading decisions. Moreover, the top teams in the league are their own specialized data analysts, including the top six teams in the division, Magic and the Mavericks are hired full-time data analysts, resident team. The impact of data analysis on the team's record has also been reflected. Their average winning percentage reached 59.3% of the 15 teams that spent their time analyzing data, compared to an average of 40.7% for teams without the analysis.

Presumably, in the future with the help of somatosensory tracking, data analysts in the NBA team, but also has the analysis of assistants and grounds. The somatosensory track into the stadium, will also further deepen the process of sports big data.
