The habitat includes an elephant enrichment wall that has numerous holes for elephants to stick their trunks into as they search for food on the other side.\u003C\/p\u003E\u003Cp\u003EThe elephant enrichment wall at Zoo Atlanta recently received an upgrade thanks to a Georgia Tech Ph.D. student. Arianna Mastali designed an audio enrichment system that uses computer vision to detect when an elephant sticks its trunk into the enrichment wall as it searches for food. The system then sends a signal to play a unique tone from a nearby speaker that corresponds to each hole. So far, Mastali has found that elephant wall interactions have increased by 176%, and the elephants are visiting the wall even when there isn\u0027t food behind it.\u003C\/p\u003E","format":"limited_html"}],"groups":[{"id":"47223","name":"College of Computing"},{"id":"1188","name":"Research Horizons"},{"id":"50876","name":"School of Interactive Computing"}],"keywords":[{"id":"174264","name":"elephants"}]}}}
