GoSense is close to its users and the field. Here is a selection of frequently asked questions about the products and the company. Make your choice!

Rango works on iPhone. Starting with iPhone 4S. Rango also works well with Android. However, there are some prerequisites for pairing Rango with your smartphone. Make sure your smartphone has Bluetooth 4.0 or higher and a version of Android 5.0 or higher.

Specialized smartphones like the Doro Claria Vox from Kapsys or the Olga phone are not compatible with Rango. However, the SmartVision 2 is compatible with Rango.

If you have any problems with your Rango, remember to restart your phone; once your phone is turned on, check that Bluetooth is enabled, turn on your Rango mobile app, and then your Rango. Once Rango is connected, everything should work again. If the problem persists, visit forum.gosense.com. Finally, if the problem persists, contact us at support@gosense.com

Rango has been designed to be impact resistant, thanks to two glass-filled plastic parts at the ends. Rango has undergone several crash tests, which were very conclusive. However, it is possible that your Rango may be damaged after a violent impact. Because you don’t want Rango to fall off your cane while you’re moving, you may tend to overtighten the clamping screw built into the Rango’s attachment. This creates a lot of pressure on the grip of your Rango, which weakens its shock resistance. This can cause the hanger to crack and eventually fail. One way to ensure that your Rango is securely attached and will not fall out is to shake your cane with Rango in an up and down motion, tapping the tip of your cane on the ground. If Rango resists this test, you can leave without fear.

A repair kit will soon be available on our website www.gosense.com in e-commerce.

Rango complies with the « IP 65 » protection rating, which means it is fully protected against dust and splash water from all directions. In rain, fog, snow or strong sunlight, Rango will work and protect you.

Rango was designed to work outdoors. However, Rango can also work indoors. You may simply be alerted more often to the presence of a nearby obstacle. That said, remember that when you put your cane upright and bring it towards you, Rango understands this and deactivates itself to save energy. The idea is that, by your behavior, you are telling Rango that you are no longer in the action of searching for obstacles with your cane; thus, you conserve your battery and Rango avoids disturbing you with unnecessary audible alerts. However, if you wish to keep the detection active, simply leave your white cane in a moving situation and Rango will remain on the lookout. If you stop scanning, Rango’s detection mode changes.

Thanks to its « u » shaped hook and its tightening screw, Rango can be fixed on all types of white canes. If you have a round handle with a flat face, check that your tightening screw is fully unscrewed. Then place the flat side of your handle between the two grooves on the back of Rango. This will make it easier for you to « clip » the clamp. If you have difficulty closing the ring, slide your Rango down until you can close it again.
Finally, if your Rango moves, tighten the clamping screw with a coin.

For Czech white canes, it is possible that your handle is too big. We therefore advise you to lower Rango until you can clip the grip. You can also put a 3 cm wide grip around your handle (which can be supplied by GoSense on request). The grip will help the Rango clamp to your white cane.

If you are looking for a new cane, we recommend a cane with a round handle without a flat surface, as this will make it easier to attach the Rango.

Rango is used on a white cane, it was designed that way. It is important to sweep so that Rango can correctly detect dangers. On the other hand, the dog could be considered by Rango as an obstacle.

At GoSense, we take pride in designing robust and durable products. It is in this dynamic that a repair kit will soon be available on our website in e-commerce. A replacement service for your battery is also planned.

Free software updates will also be offered regularly to improve the performance of your Rango.

Vibration feedback can be difficult to perceive, especially when wearing gloves. Understanding the different vibrations is often laborious and requires a more difficult learning curve. In addition, the information they can transmit is limited.

At GoSense, we decided to use our instinctive ability to detect sounds in space. After all, it’s easy for anyone to detect where sounds are coming from. This is part of the reason why Rango is intuitive and will soon allow you, with a little training and adaptation, to locate obstacles in 3 dimensions.

However, in order to provide a solution for people who still prefer vibrating feedback, we plan to make Rango compatible with a vibrating bracelet.

You can put on only one earpiece when using Rango except when the 3D sound interface is activated. To benefit from the 3D sound feedback, and thus to easily locate the obstacle, it will be essential to put your earphones on both ears, making sure to put the right earphone on the right ear and the left earphone on the left ear so that the 3D sound feedback is accurate.

You can use Rango with any type of earphones, traditional or open. We recommend that you use open earphones rather than in-ear ones, which will cut you off from your surroundings. That’s why GoSense has included a pair of external earbuds in the Rango kit, the noor.
These headphones are in Bluetooth since September 2021. We recommend that you use Rango with the noor and not with other Bluetooth headphones, as Bluetooth technology has a high latency, which means that your Rango will detect obstacles late. Your user experience may be diminished. With the noor, you don’t feel the latency, because we master the Bluetooth protocol. That’s it.

First, for Rango’s 3-D sound alert to work properly, be sure to position your noor earphones correctly. The right earpiece to the right ear and the left earpiece to the left ear.
Rango’s sound alert is said to be 3-dimensional because GoSense positions the sound alert in your environment. In other words, the sound alert can come from the right, center or in front of you, or from the left. Where the sound is, is where the obstacle is. It is simple. So if the obstacle is on the left, you will hear a sound in your left ear, if it is in front of you, you will hear a sound in both ears, and if it is on the right, you will hear a sound in your right ear.
To indicate whether the obstacle is near or far, the warning sound changes according to the distance. If the obstacle is far away, the alert sound is slow and low-pitched. The closer the obstacle is to you, the faster and higher the alert sound becomes.

We do not recommend it. Rango has been designed to be used with a white cane. It is indeed important to sweep so that Rango can correctly detect hazards. So technically, if you scan but hold Rango in front of you, it is possible, but not very ergonomic. Also, Rango does not yet detect holes, so a white cane is all the more necessary. Finally, it allows you to signal better.

Yes this will be possible with future updates. So, in the settings of your Rango mobile application, we will allow you to choose from a family of obstacle alert sounds. You will also be able to customize your voice information.

Wizigo can be used with the phone in the pocket. For this a calibration is necessary. By pressing the button to lock the screen. The calibration is done in 2 steps. Follow the vocalized instructions. Attention it is important to put the phone in a tight pocket so that the phone does not move.

Once the synchronization of Wizigo is done, even if you lose your internet signal, Wizigo continues to work. If the synchronization could not be done before the loss of internet signal, then all your newly created data on mywizigo.com will not be accessible from the mobile application yet.

Wizigo guides you at all times. For the moment Wizigo offers you an external guide. The inner guide is under development.

In the near future Wizigo will work indoors thanks to the connection to Bluetooth beacons called « Beacons » and the new generation Wizigo Bluetooth beacon, owned by GoSense. Wizigo combines several technologies: GPS, internet, pedometer, Bluetooth… etc. Wizigo can connect to its own Bluetooth beacon, but also to other beacons whose Bluetooth protocol is accessible.

It’s coming soon and under development. Soon Wizigo will allow you to connect to the sound beacons that embody the Bluetooth technology. Thus, Wizigo will be able to trigger the sound signal of these same beacons. Whether it is for the sound signal of traffic lights, but also sound beacons for traveler or visitor information.

Wizigo is a universal mobile application accessible to all. It works with or without a screen reader. Its graphical interface has been simplified as much as possible to be accessible to visually impaired people.

Wizigo works on iOS for all iPhones. Wizigo is currently being developed for Android.

Wizigo is free for users, but paid for professionals, via licenses sold by GoSense.

The Wizigo license portfolio for professionals consists of 4 distinct licenses:

1 - Outdoor guiding license. Offered by GoSense.
2 - Indoor guiding license (requires a hardware part in addition to the software part).
3 - License to guide on platform to the right train car door (requires a hardware part in addition to the software part).
4 - License activation of a Bluetooth beacon or a sound beacon.

The Wizigo offer consists of two independent and complementary parts: a software part (mobile application, mywizigo web platform for professionals) and a hardware part (Wizigo beacon). You can subscribe to the Wizigo offer through a one-time purchase, a purchase and annual subscription, or only through an annual subscription.

The MyWizigo web platform allows you to manage your database, your user account (change your Wizigo password … etc.). The platform is accessible to visually impaired people. For professionals, MyWizigo also allows you to control your fleet of Wizigo beacon. The transfer of data between MyWizigo and the mobile application is done in real time.

MyWizigo can be used by anyone who wants to help and lend their eyes to visually impaired users. Everyone knows the accessibility issues of his city or his neighborhood and can build data : create sound routes at the level of sidewalks and crosswalks, create points of interest, mark areas of work. With MyWizigo you have a tool that allows you to participate in the accessibility of your territory and your city.

For the moment Wizigo is a GPS that has been designed for pedestrian use. Wizigo cannot be used in a car or on a bicycle.

Wizigo works with all types of headphones. Traditional or extra-auricular. Whether they are wired or Bluetooth.
However, Wizigo is even better with GoSense’s « noor » earphones. With all the electronics on board and a neckband, the noor feeds multiple data into Wizigo’s algorithms, and improves the accuracy of guidance, including significantly improving the accuracy of GPS reporting. With GoSense noor, Wizigo knows precisely the user’s orientation and speed. As a result, Wizigo’s accuracy increases from 5 meters and above in custom trips and with traditional earphones, to 1-3 meters with GoSense noor earphones. In addition, the noor headphones also significantly improve the 3D sound interface. This makes it more natural and intuitive, as the noor headphones allow for better positioning of the guidance sound in the user’s space.
So you can use Wizigo with any commercially available headset, but with GoSense noor, Wizigo will be more powerful and intuitive.

A marking, by a pin, is present on your right earphone. The left earphone is without marking. So you can easily differentiate the right earpiece from the left one.

Your noor earphones were designed for long-term use and for use during sports. They are therefore resistant to water and sweat. The noor earphones are comfortable and supportive, so you don’t even notice them. You don’t feel them. Even with glasses or a mask.

The GoSense noor app is free and can be downloaded on all platforms from the Google Playstore or your App Store.

The battery life of the noor is at least 8 hours in the case of a continuous call or +10 hours in the case of continuous listening to your music.

The noor have a charging time of less than one hour and 30 minutes, for a full charge.

When you purchase a pair of noors, GoSense provides a 2-year product warranty. This warranty covers any damage to your noor, provided it is used in accordance with GoSense’s intended use.

Go- for the dynamics of innovation, the technical and human challenge. The Go also represents the idea of movement, of mobility.
Sense- is the idea of collaborating in a project that makes sense, but also of working on the human senses.

GoSense- means both « A new meaning for mobility » and « Let’s do something that makes sense ».

The name Rango was initially a code name given by our designer, because the prototype we were working on at the time reminded him of a chameleon with its big eyes that look everywhere (the sensors). Clinging fixedly to its cane and merging with it, like a real chameleon on its branch, Rango protects its user. This code name combined our wish to personalize the product and to have the -Go- of GoSense.

GoSense, innovation makes sense!

The name came from an ideation session. What came out of it was an acronym. The one for NOuvelle OReille which becomes noor when reduced to the strict minimum.
Secondly, noor has many roots: Greek, Latin and Arabic. And as many meanings: noor means light in Arabic, evokes the idea of appeasement in Latin and compassion in Greek. noor can be read in all languages and has a positive meaning each time.
