Size of soccer field: 5,486.4 X 3,657.6 cm Horizontal FOV of WiiMote is 20° The result of tan(radians(20))=0.36397

Calculate distance of WiiMote based on camera’s field of view (based on this page: http://www.wiimoteproject.com/wiimote-whiteboard/wiimote-camera-angles/)

(5486.4/2)/0.36397 = 7536.88cm = 247.27ft (this is how far above a soccer field the WiiMote would have to be to capture the whole area)

rule of thumb: distance of WiiMote to field is width of field * 2
