EchoVision is an interactive mixed reality art experience that simulates bat echolocation using custom-designed, handheld, bat-shaped masks based on the open-source HoloKit headset. As users initiate sounds, they experience echolocation—the remarkable navigation method bats employ in darkness—through visual representations of propagating echoes mapped onto the real-world 3D shape of the surrounding environment, scanned in real-time by the LiDAR sensor of a smartphone mounted on the masks. By providing a unique glimpse into how non-human creatures perceive their sensory world, EchoVision promotes an ecocentric design perspective, fostering interspecies understanding and appreciation.
