Using the obstacle detector

The NAVIGATE button is located furthest away from the sonar sensor and is smooth in texture. It is a multifunctional button where you’ll be able to access some of the Sunu Band’s important navigation features such as the Sonar – Obstacle Detection and the Place Finder.

I. Activating the Sonar or Obstacle Detector

Sunu Band’s sonar can detect obstacles that are up to 16 feet (5.5 meters away). Vibrations pulses that you feel on the wrist tell you how far or close you are to an obstacle. You feel intermittent pulses when the obstacle is within range (and in the same direction) of the sonar. Then, the  pulses become more frequent as you get closer to the obstacle. Finally, the pulses become constant when you are sufficiently close to the obstacle. You can image that the obstacle or object is now within your personal space, about 2 feet away from you.

Step 1: Press or click the NAVIGATE button to activate the sonar sensor. You’ll feel a long vibration followed by either one or two pulses that indicate the current sonar mode.

There are two sonar modes. You can switch between mode by swiping on the touchpad. 

Indoor (short-range) mode:  Swipe-In on the touchpad to select this mode. You’ll feel one pulse. This mode detects obstacles at a range of 6 feet (2 meters) and has a narrow detection area. It is optimal for navigating indoor spaces, finding doorways, corners and gaps, trailing or following in a line.

Outdoor (long-range) mode: Swipe-Out on the touchpad to select this mode. You’ll feel two pulses to indicate that this mode is active. This mode detects obstacles at a range up to 16 feet (5.5 meters) and has a wide detection area. This mode is optimal for outdoor spaces, finding sign posts, tree branches, bushes etc.
