This video contains testing of Owlie at different distances. Owlie beeps from the buzzer and vibrates from the pager motor only once between 150 cm and 100cm from an object to let the user be aware of an object in that distance. As the object gets closer between 100cm and 30 cm, it beeps and vibrates more frequently about 5 times. Then when it gets too close less than 30 cm, it keeps beeping and vibrating until the user moves away from the object. Here is the link to the video clip.Testing of Owlie at different distances
