SleepLa is a Unity based Virtual Reality meditation app for sleeping and waking up using the power of voice. In the sleeping mode the environment responds to the sound of an exhale giving a sense of agency to a breath excercise. The waking mode transforms a forest from night to day depending on the pitch of their voice. This demonstrates the potential of voice to produce stimulating and naturalistic experiences in Virtual Reality. Documented here is a detailed walkthough of the application development and ideation.
