Precision Game Statistics Keeping iNterface


Donnie Lytle ITGM 705 2/16/2011 Exercise 2, Unconventional Computer Input Concept: PGSKN Precision Game Statistic Keeping iNterface Eight seconds left in the championship game, down by six points the home team lines up just six yards from the end zone, it is the fourth down. The crowd rises to their feet as the ball is snapped to the quarterback, silence falls on the stadium as the ball soars into the air. The pass is complete, the receiver leaps toward the end zone and is tackled on the line. Anticipation mounts as the referees argue over the play, one says the ball was short another says it was a touchdown. After ten minutes and a commercial break’s worth of challenges and slow-motion replays, the refs deem the ball short of the goal. But was it really? This issue seems to be a fairly common one in the game of American football, though not often as dramatic as depicted. Isn’t it odd that in today’s high-tech world of instant information and precision statistics Americans, of all people, would settle for an “eyeballed” and “guesstimated” way of handling their favorite sport’s base mechanic (the movement of the ball)? Not anymore. Radio technology has brought precision data collecting to the great American sport of football. How? With the technology of PGSKN.


PGSKN PGSKN itself refers to the actual interface in which the real-time data is displayed and navigated by the user. Sportscasters and hardcore fans alike will have access to the PGSKN through their computers and smart phones. The PGSKN will display live and archived pinpoint accurate statistics in a simple to use fashion. Previously difficult and near impossible statistics like exactly how far and fast the ball was thrown or run during a given play will be what PGSKN users become accustomed to. PGSKN ready stadiums will also be able to broadcast statistics live, so viewers at home will know how far that last punt actually was.


Questionable judgment calls will be a thing of the past as the location of the ball on the field will be known precisely at all times. Touchdowns and first downs will be much easier to declare or deny as refs will be linked to the PGSKN at all times. Finally no more guessing in football, at least when it comes to the position of the ball. So how does it work? The way in which PGSKN collects its data is where the unconventional input method comes into play. Instead of statistics being entered by people on the sidelines, the information being fed to the PGSKN comes straight from the field. Inside every PGSKN ready football rests a small, inexpensive, and durable radio transmitter. This transmitter is designed to add no weight to the football (the materials within the ball will be proportioned so that the addition of the transmitter makes a PGSKN ball exactly as heavy as a non-PGSKN ball) and will broadcast one of the hundreds of PGSKN reserved frequencies. The transmitter is also orientated to the length of the ball, so that a simple calculation in the PGSKN data center will be able to show if the tip of the ball made it across the line. But a transmitter alone will tell the PGSKN far too little information to be helpful. That is why every PGSKN equipped field will incorporate two signal receivers, on each goal post.

The angles and lengths are filled in with data received by the transmitter, pinpointing the exact location of the ball at all times.


Through simple and precise radio triangulation, the position of the transmitter, and thus the football, will be known at all times. Data collected by the receivers will be sent to the PGSKN database, where it will be crunched and calculated and then uploaded directly to the PGSKN in real time. Therefore, the players’ moving of the ball around the field is the input method in which the game’s statistics are recorded, calculated, and supplied to the user interface (be it on a computer, iPad, or smart phone).
