 In [[inside-out tracking]], markers such as QR codes can be placed in the environment to serve as reference points.
-In [[outisde-in tracking]], markers such as light-emitting diodes can be placed onto the object so it can be tracked by the external camera(s). The camera or multiple cameras would follow the movement and position of the marker to figure out its position and orientation in 3D space. Different markers can be placed on different objects so they can be tracked independently.
+In [[outside-in tracking]], markers such as light-emitting diodes can be placed onto the object so it can be tracked by the external camera(s). The camera or multiple cameras would follow the movement and position of the marker to figure out its position and orientation in 3D space. Different markers can be placed on different objects so they can be tracked independently.
 Tracking systems that do not use fiducial markers are called [[Markerless tracking]].
