     Current inanimate enrichment techniques can be divided into two categories: active forms such as manipulanda, foraging devices, and swings; and passive forms like video and sound. This study assessed the use of an interactive projection apparatus to provide active stimulation through contact and passive stimulation through moving images. Thirteen adult rhesus macaques (three female), of which nine were individually housed, were given access to the apparatus during six 10 minute trials. Through video analysis we determined frequency and duration of contact with three categories of stimuli: treat on the projection, static area of projection, or moving projected element. Females spent more time contacting the apparatus than males (p<0.02) and total time spent in contact increased across the first three trials, then decreased across the last three (p<0.02). Individual use varied, and the results were stratified into three user categories: low-users (three males: <50 contacts), medium-users (six males, one female: 250-100 contacts) and high-users (two females, one male: 350-850 contacts). The low-users and five medium-users focused primarily on treats; the remaining medium-users and the high-users engaged with active elements most often. These results suggest that for some macaques, interactive projection provides active stimulation; for others, it serves as a novel foraging situation. Additionally, the development of applications for mobile devices is a promising next step to increase accessibility of interactive enrichment.
