This paper proposes a new Mixed-Reality presentation of spatio-temporal behaviour of a moving object in a observer viewpoint. The behaviour of the moving object was recorded in advance as a sequence of pairs of spatial position and its texture by environmental camera. A reviewer can see simultaneous replays of the moving object so that he/she can shorten the time to browse the behaviour. Since large number of simultaneous replays increases the chance of overlapping textures, we propose the method to determine the best number of replays. We also propose an enriched visualization of trajectory of the moving object so that the reviewer can recognize the moving direction of the object easily. We have conducted subject tests on our proposed traject visibility and simultaneous replays of the moving object and show the results.
