The part in bold explains why direct sunlight makes the problem worse as it prevents the sensor bar/remote detection.Thankfully, Wii Sports Resort handles this issue rather elegantly through an option called "Sensor Bar Assist," which is enabled by default. This allows the Wii to recalibrate the controller every time it's pointed at the screen (or more specifically, the sensor bar). Basically, in an ideal environment, your controller should automatically recalibrate itself often enough (whenever it "sees" the sensor bar) that you shouldn't notice any problems. However, not everyone plays in an ideal environment, and this can actually result in "Sensor Bar Assist" making the problem worse! But in order to resolve this issue, it helps to understand how exactly the "Sensor Bar" works.
