This study evaluated the use of facial recognition technology for cognitive enrichment in zoo-housed Western lowland gorillas. A machine learning-based system was integrated into a finger maze to track individual gorillas' device interaction, achieving 97% accuracy in identification. While the technology successfully automated data collection on engagement, it required significant hardware and expertise, making it feasible primarily for long-term projects. Full automation of cognitive enrichment assessment remains challenging, necessitating additional tools such as infrared sensors to track specific behaviors.
