How it can best improve the lives of animals, particularly those in captivity, however, has remained an open question. Scientists from Aalto University, in collaboration with Korkeasaari Zoo, have designed and built an on-demand video device for white-faced saki monkeys to activate as and when they like. While enrichment systems for zoo animals have been around for some time, very few offer animals the ability to choose when and how they use the device, even though choice and control are known to promote animal welfare.
