Imagine the feeling of swinging at a baseball going 100 miles per hour-without leaving your living room, or being in race car as it roars down the track, while you are sitting on the couch.

These are just some of the ways that sports business leaders say virtual reality (VR) will revolutionize how people train for and experience sports. Virtual and augmented (增强的) realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds and read the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”

Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks. It is now moving into sports, and shows its Formula One (F1) racing simulator (模拟器). The seats stimulate the force of gravity, speed and every shaking as F1 champion Lewis Hamilton zips around city streets.

A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent by the car. “They could broadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heart beat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”

One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences. Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.
