As technologies diversify and become embedded in everyday lives, the technologies we expose to animals, and the new technologies being developed for animals within the field of Animal Computer Interaction (ACI) are increasing. As we approach seven years since the ACI manifesto, which grounded the field within Human Computer Interaction and Computer Science, this thematic literature review looks at the technologies developed for (non-human) animals. Technologies that are analysed include tangible and physical, haptic and wearable, olfactory, screen technology and tracking systems. The conversation explores what exactly ACI is whilst questioning what it means to be animal by considering the impact and loop between machine and animal interactivity. The findings of this review are expected to form the first grounding foundation of ACI technologies informing future research in animal computing as well as suggesting future areas for exploration.

Orangutans show interest in sound-based stimuli, but the auditory enrichment they are usually provided with is either based on human-music, or does not allow for control and choice. In this work-in-progress paper, we describe the design of sound-based enrichment by means of the manipulation of tangible non-technological elements. In doing so, we demonstrate how Animal Computer Interaction research can help in providing animals with more control over auditory stimuli, as well as demonstrating and justifying a novel modality for interaction based on orangutan behavior within our ongoing study. We overview our proposed evaluation, identifying how - through embodying notions of control and choice in design - our proposed system allows for orangutan use to inform ongoing development and design of auditory enrichment.
