Half a million soccer fans will visit Brazil to attend this summer’s World Cup—but they won’t be seeing the same game as in years past. The pitch will feature some impressive new technologies, starting with a ceremonial kickoff by a paralyzed teen outfitted in a mind-controlled exoskeleton. Here’s what’ll come next.
2014世界杯期间，巴西将有50万球迷蜂拥而来，而本届世界杯将是他们所看到的最不同的一届。下面将为您盘点一下，那些让人印象深刻的高科技。这场科技的惊喜始于一位瘫痪少年，他身穿可意念控制的“机械外骨骼”为世界杯开球。
1 PackBots
1、反恐机器人（PackBots）
Instead of clearing bunkers and crossing minefields in Afghanistan and Iraq, 30 iRobot 510 PackBots will check suspicious packages and provide extra surveillance at the dozen World Cup venues.
30个PackBots机器人为分布在全国的12个足球场提供特别监控，包括检查可疑包裹、清除障碍物。这种机器人曾在阿富汗和伊拉克战场帮助探测掩体中的危险。
2 4K Broadcast
2、4K超高清赛事直播（4K Broadcast）
Sony and FIFA will broadcast the July 13 final match live in super-high-res 4K. Carriers who devote the bandwidth will get four times the resolution of 1080p— making it nearly impossible to fake being fouled, right?
7月13日的世界杯总决赛，索尼将与国际足联携手推出最新的4K转播技术，清晰度能达到1080p高清分辨率的4倍，犯规、假球将无所遁形。
3 GoalControl
3、门线技术（Goal Control）
Fourteen video cameras mounted high in the stadium—seven pointed at each goal—capture the ball’s exact position and send a vibrating signal to the ref’s wrist watch when it passes the goal line.
14个摄像机分布在球场顶部，7个分别对准两个球门，用来捕捉足球的准确轨迹。当球入门时，将同时向裁判手表发送进球感应波。
4 Vanishing Spray
4、消散式喷雾（Vanishing Spray）
Argentinian sports journalist Pablo Silva tested hundreds of foaming emulsifiers to come up with this shaving cream like product, which evaporates within two minutes.* Refs will use it to mark off free kicks.
阿根廷足球记者Pablo Silva实验了数百种泡沫乳化剂，最终开发出了这个类似剃须膏，可在2分钟内消散的产品。它将被裁判用于任意球局，为防守人墙脚下划线。
5 Brazuca Ball
5、“桑巴荣耀”足球（Brazuca Ball）
A record-low six panels makes for less water uptake and fewer seam defects. Plus, the cool panel shape means no large smooth areas— the source of the knuckle-ball effect that plagued the last two FIFA balls.
桑巴荣耀用6块螺旋桨型皮面组成，更防水，同时尽量减少球面缝合带来的使用缺陷。另外，酷劲十足的螺旋桨型，意味着更防滑。要知道，由于球滑导致变线，可是上两届世界杯的噩梦。
