Sunu Band

Sunu Band is the world’s first fully-accessible smart-watch that combines sonar or echolocation technology with precision haptic feedback to augment perception, awareness and independence. Sunu Band uses a compact ultrasonic sensor within a beautifully designed smart-watch to detect the proximity of objects that are within your environment – allowing you to safely move about in environments with confidence and ease.

Why Use It?

Why Use It?

Sunu Band

Sunu Band is for anyone living with impaired vision or partially sighted who wants to improve their mobility. The smart-bracelet is augmentative, and can work alongside other aids (like the white cane or the guide dog). Sunu is recommended for children above the age of six (6), teens and adults. Sunu Band can help people who are: totally blind, have low vision or are partially sighted and experiencing vision loss, due to Macular Degeneration (AMD), Glaucoma, Cataracts, Retinitis Pigmentosa (RP) or by anyone who wnts to improve their awareness.

With Sunu Band you will own your environments. You can detect and locate obstacles up to 14 feet away, find thresholds or openings to walk through, follow or avoid people around you with precision and feel what’s around you without physical contact. With Sunu you navigate in a simple, smooth and secure way.

Sunu Band

Sunu Band is optimized with two different operation modes for indoor and outdoor scenarios. The indoor mode has a shorter range (7 feet) and is enhanced to detect openings and thresholds, like aisles in a supermarket, exits in a building, spaces between people and so on. The outdoor mode has a longer range (14 feet) and covers a wider area allowing you to detect obstacles above the knees up to head level, like trash cans, phone box, hanging tree branches, etc.

Thanks to its ergonomic design, the Sunu Band can be pointed with minimal movements from your hand, enabling you to feel your surroundings in a very discreet and quick manner. Sunu Band doesn’t interfere with the other senses because it provides vibration feedback and it’s non-obtrusive as you still maintain free use of your hand.

Sunu Band is truly augmentative as it can be used alongside other mobility aids, like the white cane or with a guide dog. Its sonar transducer emits at a frequency that is safe around dogs and other pets.

How does Sunu Band work?
Sunu Band

Sunu Band uses an ultrasound transducer as a proximity sensor. The ultrasonic wave emitted from the transducer bounces back from objects that are within the sensor’s path and direction. The resulting ‘echo’ is detected by the same sensor, and then is processed and converted into vibrations pulses. These pulses become more frequent as the obstacle gets closer.

Sunu band also has an embedded 3 axis accelerometer that is sensing inclination to modulate the emitting ultrasonic wave. This allows the device to automatically adjust the range while pointing upwards, so it doesn’t detect obstacles way above head level (like ceiling lamps, fans or the ceiling itself) and only detect obstacles that can be a threat to the user.

  • Gesture Control – Allows you to quickly manipulate all the band functions with one hand using simple hand gestures.
  • Vibration Clock – Keep track of time with Sunu’s haptic clock. Vibrations discreetly tell you the time with a simple abacus like system.
  • Sunu Tag – Find your personal articles with this tiny tracker. Vibrations on the band or your smartphone indicate the Tag’s proximity while an alarm on the Tag helps you to find it quickly.
How does the Sunu Tag work?
Sunu Tag

Sunu Tag is a low-power ‘beacon’ that can be clipped to any personal belonging such as keys, backpacks, luggage, to keep track of it and locate it in case it gets lost. Sunu Tags can be activated via Bluetooth from the Sunu Band or your smartphone within a 30 feet range of the tagged article. When activated, the phone or the band’s increasing pulses indicate the Tag’s proximity and the Sunu Tag ‘chirps’ allowing the user to readily find the item.

How It Works

How It Works

Sunu Band is a multifunctional smart-watch that has a built-in sonar sensor. The Sunu Band enables you to:

  • Tell time with the vibration watch.
  • The sonar sensor enables you to perceive objects or obstacles that are within your environment.
  • Connect with Sunu Tags to track and find your personal articles.
Parts of the Sunu Band:

Sunu Band Parts
A: Sonar Sensor – The sonar sensor is a round metal cylinder that is discreetly embed within the Sunu Band. The sensor is a transducer that emits ultrasounds as well as detects the echo or reflected sound-waves that bounce back from objects or obstacles that are within your environment.
B. Buttons 1 and 2 – Sunu Band has two (2) buttons which are located at one side of the device. The buttons allow the user to interact with the Sunu band interface. Button 1 or HOME button is closest to the sonar sensor, while Button 2 is furthest away from the sonar sensor.
C: Touch Pad – The touch pad is the flat top surface of the Sunu Band. The touch pad allows users to interact with the interface.
D: Charging Inlets – The charging inlets are located underneath the Sunu Band (on the opposite side to where the sonar sensor is located. These inlets connect to the micro-charger and are used for re-charging the Sunu Band’s battery.
E: Standard Watch Belt and Buckle – Sunu band come with a standard watch belt and buckle that is hypoallergenic. You may customize or change your belt by visiting any jeweler.

Sunu Band Interface

Sunu Band’s interface works similarly to a smartphone or tablet. The physical interactions with the device are primarily done through the buttons and the Touch Pad.

Sunu Band Buttons

The two buttons which are both located at one of the sides of the Sunu Band. Button 1 or HOME Button is located closest to the sonar sensor, while button 2 is furthest away from the sensor.

You interact with the touch pad just like you would with any smartphone or tablet. The two primary kinds of interactions you will be doing with the touch pad are:

Sunu Band Touch Interactions

Touch Interactions:

  • Tap+Hold (Tap and Hold) — Place one or two fingers on the touch-pad and hold for 3-5 seconds, and then release.
  • Double-Tap — Touch twice on the touch-pad with either one of two fingers.
Sunu Band Swipe Interactions

Swipe Interactions:

  • Swipe Up — Slide a finger in the direction that is going away from the sonar sensor.
  • Swipe-Down — Slide finger in the direction towards the sonar sensor.

Orientation

You can wear Sunu Band on either hand, just like any watch. Wear your Sunu Band with the sonar sensor on the same side as your thumb, as shown in the image below. Then adjust the belt and buckle until the Sunu Band is securely around your wrist.
