| Summary: | Design and evaluation of real-time descriptive mediation (RTDM) for live aquarium exhibits was proposed to support the participation of visitors with and without vision loss. RTDM was developed to address learning, entertainment, restorative, and social motivations. Data was collected during a lab study with adults to get feedback about the RTDM and compare it to traditional docent presentations and audio tours. Findings show that the RTDM made it possible for participants to address their exhibit motivations and led to specific personal and social aspects of participation. A majority of participants with and without vision loss reported that the RTDM was supportive of their motivations and perceived it to be more effective at supporting learning, social, and restoration motivations compared to audio tour and docent mediation. The main contributions of this work are in: 1) developing evidence-based information design criteria for mediation at live animal exhibits; 2) demonstrating that mediation designed to support exhibit motivations can facilitate participation in adults with and without vision loss; and 3) validating participation as a design goal.
