ULTRASONIC SENSOR
Your WeWALK uses an ultrasonic system to detect obstacles. Do not press on the ultrasonic sensor positioned at the front of the handle or try to manipulate it in any way.
Any damage to this sensor may cause the product to perform poorly.

TACTILE BUTTONS
When the WeWALK is switched on and obstacles are detected, the two buttons will vibrate. It is important that you do not press hard on the buttons as this will reduce the vibration intensity. You should experiment with positioning your hands to get maximum sensitivity. The wearing of thick gloves is not recommended as this will also reduce the intensity of vibration feedback.

SPEAKER AND MICROPHONE
WeWALK has a speaker and microphone for audio feedback and voice commands.

POWER BUTTON
Use the power button to turn the WeWALK on or off.

TOUCHPAD
The touchpad works by sensing your finger movements and pressure. The touchpad
is used to control the connected WeWALK smartphone app. Usage with gloves is not recommended as this may decrease the performance of the touchpad.
More information on gestures can be found in a separate section. To see other supported gestures and their functionalities, check support.wewalk.io or the tutorial tab on the WeWALK smartphone app.

FRONT LED
The front LED is used to improve your visibility to others in the dark and can be enabled or disabled as required. Additionally, the LED can be used as a visual reference to show that WeWALK is turned on.

MICRO USB INPUT
The micro USB input is used to charge the battery of your WeWALK device.

9. BEGIN WITH THE “TRAINING MODE”:
   We designed a training mode for you to learn how to use WeWALK. With this training, you will be able to practice using and holding the WeWALK Smart Cane.

HOLDING AND USING THE WeWALK SMART CANE
WeWALK should be held and used using regular cane technique and is not a replacement for good cane technique. WeWALK should be held in the ‘handshake’ hand position with the rounder part of the device sitting in the palm of the hand, and the thumb resting on the tactile buttons on top of the device. The tactile buttons, touchpad, and ultrasonic sensor should face forward and always be on top.

WALKING WITH WEWALK

The traditional white cane is used by moving the cane from side to side in a tapping or sliding motion where the next footstep will fall. This ensures that obstacles can be detected in the user’s immediate vicinity by utilizing the tip of the cane to touch the obstacle. Additional obstacle detection is obtained via the ultrasonic sensors incorporated into the handle, thus giving more advanced warning to the user of obstacles in their path and between head and waist level.

When using WeWALK, it is imperative to use traditional white cane skills especially for locating drops such as curbs and steps, or tactile paving. Before you start using WeWALK, experiment with the various obstacle detection range options to find out the limits and capabilities of the product. Choose the length of the white cane according to your height.

WeWALK is designed to detect the obstacles between your head and waist level, so the obstacles in this range should be detected at a distance of at least 1 meter before hitting the obstacle. For example, a low-hanging sign is at a height of 170 cm and the user is 175 cm tall, so they might hit the obstacle. The green area indicates the detection area, at these distances the Smart Cane vibrates and warns the user about the obstacle.

When your WeWALK gives you an obstacle warning during normal use, you can gently swipe your device to the left and right to detect exactly where the obstacle is located, how wide the obstacle is and where the obstacle stops blocking your path. When you move your WeWALK to the right and left, you can perceive the objects that are in front of you and you can confirm the accuracy of the obstacle detection signal.
In the unlikely event that WeWALK’s electronics fail while you are out, you will still be able to use it as a traditional white cane to reach your destination.

FREQUENTLY ASKED QUESTIONS

Can I fold and collapse my WeWALK Smart Cane like my regular cane?
Yes, you can also attach the supplied wrist strap to your WeWALK and place it in its carry bag to protect and transport it. As with regular cane technique, we do not recommend using WeWALK to walk with the wrist strap around your wrist. If the cane were to suddenly collide with an obstacle, this may exert excess force on your wrist.

1. Thread the thin loop of string through the wrist strap attachment hole.
2. After the loop is fully threaded, open it and pass the strap handle through the loop. Pull the remainder of the strap handle upwards to secure the wrist strap to the unit.
3. You can fold the cane and use the wrist strap of your WeWALK to bind them together. Be careful when folding/unfolding the cane because of the tension in the elastic cord.

Are there any obstacles/objects that WeWALK cannot detect?
It is not possible for WeWALK’s ultrasonic sensor to detect drops at ground level such as stairs, curbs, and holes. It is therefore important to maintain good traditional cane skills when using WeWALK to locate drops. WeWALK may not detect soft fabrics or small obstacles at the limit of the range setting. WeWALK works best with hard surfaces as these provide a stronger ultrasonic echo. WeWALK can detect objects at a distance of between 80 and 165 cm from the ultrasonic sensor.

Is WeWALK suitable for use in rainy weather?
Heavy or torrential rain will stop your WeWALK from working properly and should be avoided. Prolonged or repeated exposure to water or heavy rain must be prevented as it may cause permanent water-damage to your WeWALK. If you are out with your WeWALK and are caught in heavy rain, you should immediately switch the cane off and cover it to protect it from heavy rain.
You can continue to use the WeWALK as a traditional white cane to navigate during the rain, but the obstacle detection functions will not be available whilst the device is covered. You can remove the cover, switch on your WeWALK and continue your journey as normal once the rain stops. If your cane does get wet, allow it to dry naturally in the open air at room temperature.

Which smartphones do you support?
The WeWALK App Runs on Android and iOS-based smartphones. Android based devices should have Android version 5.0 and above, iOS devices should have iOS version 10 and above. To learn more about the WeWALK app and its features, view the mobile application user guide at www.support.wewalk.io or check the training screen of the WeWALK app.

Which languages are available?
WeWALK supports English, Spanish, French, Arabic, Italian and Portuguese. Other languages will be added with updates. When a new language package is released, WeWALK will be updated over wireless connection via the mobile application.

What do the WeWALK Smart Cane sounds mean?
You can listen to all the WeWALK sounds and learn what they mean in the WeWALK app.

How can I manage WeWALK’s services through the cane? What is the voice menu?
The voice menu allows you to use many of WeWALK’s functions such as starting navigation and changing obstacle detection distance without touching your phone. The voice menu can only be used when WeWALK is connected to your phone. To access it, simply double-tap WeWALK’s touchpad. You can then swipe left or right on the touchpad to access different settings. To enter or select a setting, double tap the touchpad again. To go back or exit the voice menu, swipe the touchpad forward (swipe away from you and towards the ground).

How can I start navigation through the smart cane?
You can easily get navigation to previously saved locations via the voice menu. Double-tap on WeWALK’s touchpad to open the voice menu then double-tap on ‘Navigation’.
The following items are located under the navigation menu:

Start: Clicking on this will list the previously saved locations.
Clicking on one of the listed locations starts navigation to that location. Where am I? Announces your current location.
Save location: Instantly saves the current location.

Software features are continually being updated and improved. Please check support. wewalk.io for more information on how to use the WeWALK smartphone app.

How do I clean and maintain my WeWALK?
Do not leave your smart cane in extremely low or high temperatures as this reduces the lifespan of its electronic components. Handle your smart cane with care and do not throw it around or shake it aggressively, otherwise internal circuit boards may be damaged. Turn the device off before cleaning and use a damp and anti-static cloth.
Do not use chemical agents such as detergents.
Do not attempt to modify or disassemble your product. If the internal seal is damaged or wet, the manufacturer’s quality assurance may not be warranted by the after-sales service provider even if your product is still under the warranty period.

What should I do if my white cane part is worn out or broken?
You can replace the damaged cane with any white cane that is compatible
with our adaptors. More information can be found on our website (www.wewalk.io).
To replace the cane and attached adaptor:

1. Unscrew and remove the WeWALK device from the old cane.
2. Untie the knot in the elastic cord holding the adaptor to the old cane.
3. On the new cane, untie the knot in the elastic chord and remove the cane’s existing rubber handle. Replace this with the adaptor by passing both ends of the elastic cord through the adaptor and tying a knot to secure it. You can cut the rest of the cord off if necessary but do leave some cord past the knot to allow for ease of untying in the future.
4. Attach WeWALK to the new cane with the adaptor.
