An Introduction to Echolocation with Sunu band
What is Echolocation?
Certain animals like bats and dolphins are able to navigate their environments using sound. Echolocation is the ability to use sound and echoes that reflect off of matter in order to find the exact location of objects within an environment.
Bats are capable of producing high frequency sounds. These high frequency sound waves, known as ultrasound, interact with objects that are within the environment, and a portion of these ultrasonic waves ‘bounce back’. These reflected sound waves are called echoes. Bats listen for these echoes to know their position in space and their relative distance to objects that are within their environment.
Humans are also capable of using echolocation. Daniel Kish, President of World Access For The Blind is the pioneer of human echolocation, he has been training blind travelers to use the human echolocation technique for years. Human echolocators navigate their surroundings by producing a series of ‘clicks’. Human echolocators are trained to listen to the echoes their sound waves produce and through these soundwaves are able to gage the location of objects within their environment. Thanks to the miniaturization of sensors and precision actuators, Sunu Band is capable of realizing the electronic form of echolocation.
How Sunu Band Uses Sonar for Echolocation
Sunu Band enables you to navigate your surroundings with echolocation by combining sonar with precise vibratory feedback that you can feel on your wrist. Sunu Band uses a sonar transducer that is capable of emitting high frequency sound waves while ‘listening’ to- or detecting the reflected sounds or echoes that bounce back off objects.
The Sunu Band processes the information derived from the reflected sound or echoes and relays that back to the user via a series of precise vibratory pulses. This is referred to as haptic feedback — the use of tangible feedback to transform and relay information to the user.
Sonar is Directional
Sunu Band is only capable of detecting the echoes (that reflect off of objects) from the same direction in which the ultrasound is emitted. In other words, think of Sunu Band as a flashlight that uses sound instead of light. Just like any flashlight, the direction in which you aim the sonar sensor is where you will be able to detect the presence of objects.
The ultrasonic wave emitted from the sonar sensor travels away from the Sunu Band in the form of cone. Objects that are within the area of this cone will interact with the ultrasound and produce echoes.
Should you wear Sunu Band in a particular way?
You can wear Sunu Band on either your left or right hand. It is important to wear Sunu Band so that the sonar sensor is on the same side as your thumb. The reason for this is when you bring your arms to your side, as you get ready to walk, the natural position of your hands and wrist will allow the sonar sensor to point directly ahead.
The maximum distance at which we begin detecting the presence of an object that is in the same direction of the sonar sensor is referred to as the sonar range. Sunu Band uses two distinct sonar modes:
Short range mode: detects objects up to 4-5 ft. or 1.5 meters away. You swipe-in on the touchpad to enter into the short range mode. You will immediately feel one pulse to indicate that you are now in the short range mode.
Long range mode: detects objects up to 15 ft. or 5 meters away. You swipe-out on the touchpad to enter into the long range mode. You will immediately feel two pulses to indicate that you are now in the long range mode.
How the vibration feedback changes when you approach an object: Sunu Band uses vibrations to tell you that an object is nearby. The frequency of the vibration pulses changes as you get closer (or further away) from the object. Sunu Band changes the frequency of the vibration pulses to provide you with a sense of how close an object is. Here is what happens to the vibration pulses when an object is within range:
Intermittent pulses: mean that Sunu Band is detecting an object that is at the limit of the range of the current sonar mode. These intermittent pulses tell you that there is an object furtheR away from you.
Moderate pulsations: mean that Sunu band is detecting an object that is closer to you in range. As you approach the object, the pulses become more frequent. As you become further away from the object, the pulses become less frequent.
Constant vibration: means that an object is sufficiently close to you that you should either stop or pay close attention, you may soon collide with said object. As soon as you feel constant vibrations, you may extend your hand (or cane) and touch the object.
Sunu Band’s sonar modes are designed to enable you to navigate outdoor and indoor environments, or spaces that are more open (with less obstacles) and spaces that are more crowded. You can switch between the two sonar modes to navigate these kinds of environments.
Each sonar mode has a specific range and sensitivity. Sensitivity is the power at which the ultrasound is emitted from the sonar sensor. In other words, the sensitivity is like the volume on your stereo. Varying the sensitivity of the sonar sensor allows us to navigate various environments such as crowded space or more open spaces like the outdoors. Generally speaking, with:
High sensitivity: we are able to detect thinner objects like signposts, tree branches, bushes, etc. High sensitivity is useful when navigating outdoors like on sidewalks, or in parks, etc.
Low sensitivity: we are able to detect gaps such as spaces between people, doorways and thresholds. Low sensitivity is ideal in indoor spaces or in situations where you want to find a gap or doorway. It is also useful for trailing or queuing in a line, for example when you are traveling, waiting in line at the bank or even getting in line to order your morning coffee.
Sunu Band’s sonar mode default settings are as follows:
Short range mode: low sensitivity
Long range mode: high sensitivity
Ultimately, the sonar mode you use is entirely up to you. The Sunu App allows you to customize your sonar modes to fit specific needs. Within the Sunu App you can adjust the sonar range and sensitivity. Remember that you can revert back to the device default settings at anytime.
