Abstract
An optical tracking system includes optical source devices. The optical source devices are configured to emitting optical signals. A control method, suitable for the optical tracking system, includes following operations. A dimensional scale to be covered by the optical tracking system is obtained. Signal strength of the optical signals provided by the optical source devices is adjusted according to the dimensional scale. The signal strength of the optical signals is positively correlated with the dimensional scale.
