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. ## Key features - Simulates bat echolocation - Mixed reality art experience - Handheld bat-shaped masks - Smartphone LiDAR integration - Visualizes propagating echoes - Promotes ecocentric design perspective ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/echovision/id6499540865/reviews.md ### 5/5 — Why isn’t anybody talking about this app? *2025-02-08, version 0.2.0* This is seriously awesome! Very simple, very well done, and an amazing concept. And most of all, it’s free! It’s a fantastic little demo for the Vision Pro and it doesn’t cost a penny. No in app purchases or anything. Seriously, try this out. Even if it only gives you a few minutes of entertainment it’s really cool to see. Amazing concept. ### 5/5 — I‘m a bat. *2025-01-28, version 0.2.3* This is cool and a very creative use of Lidar! I will use this app like a party trick and to show people what lidar can do. A feature I miss is the ability to turn off the Camera feed to see the echo responses only. Also wish the delay would be less. ### 4/5 — cool bat sim! needs tones *2025-01-13* outstanding and very creative application of LIDAR tech! its amazing to use and see enhanced vision!! please consider adding tones or sound options to represent sonar-like pulses OR use both mic’s to approximate sound source location? just thinkin’ out loud. thanx dev(s)! ### 1/5 — Black screen nothing more *2024-08-22, version 0.2.0* Sadly no function on visionOS 2 ### 5/5 — Awesome app *2024-07-07, version 0.2.0* This app is awesome for listening to music. It would be really cool if you could just what the visuals look like for example just having the dots bouncing or changing the pattern that comes on ## Frequently asked questions about EchoVision ### What is EchoVision?
