How Were The Blind Spot Sensors Designed?
The Braze Mobility Blind Spot Sensors are based on over a decade of "smart" wheelchair research and development by founders Drs. Pooja Viswanathan and Alex Mihailidis. When starting the business, the founders focused on two things: How can we create a solution that is evidence-based and centered around the users’ needs? And how can we make the solution both affordable and fundable?
We use clinical evidence, user-centered design methods, and co-design with users to ensure that our products help users, their families, and therapists achieve their goals for independent mobility. Over the years, we have worked closely with clinicians, caregivers, manufacturers, distributors, and wheelchair users, in order to increase safe and independent mobility.
How Do The Blind Spot Sensors Work?
They are a set of sensors that can be attached to any manual or powered wheelchair, turning it into a "smart" wheelchair. They system provides alerts to the wheelchair user about objects in the environment through multimodal feedback (light, sound, and vibrations) empowering them to navigate safely and independently.
Braze Blind Spot Sensors do more than just alert users to objects around them. They were designed to increase the overall spatial awareness of the person using the system and can be used to help people perform activities of daily living with their wheelchair, while maintaining their independence.
The system provides feedback on both the location and proximity of obstacles, and detection detections are fully customizable. This intuitive feedback is helpful to navigate through tight spaces, by providing the user with a clear understanding of how they are positioned. Clients using the system are able to easily understand the feedback and most are able to use it to navigate within minutes.
Note: Our system does NOT detect drop-offs, soft material, or objects out of view of the sensors. Legally blind customers often use our sensors in conjunction with a white cane to navigate outdoors.

Who Can Benefit From Blind Spot Sensors?
According to Simpson (2008), up to 91% of wheelchair users can benefit from "smart" wheelchairs. Here is the breakdown by diagnosis:
|Diagnosis||Percentage that can benefit from "smart" wheelchairs||Symptom that results in decreased spatial awareness|
|Spinal cord injury (SCI)||Up to 100%||Limited head/neck movement|
|Low Vision / Blindness||Up to 100%||Vision loss|
|Multiple sclerosis (MS)||Up to 90%||Limited head/neck movement|
|Parkinson's disease (PD)||Up to 90%||Visual field neglect|
|Stroke||Up to 82%||Visual field neglect|
|Severe traumatic brain injury (TBI)||Up to 60%||Inattention|
|Alzheimer's disease (AD)||Up to 48%||Inattention|
|Amyotrophic lateral sclerosis (ALS)||Up to 26%||Limited head/neck movement|
It is important to not only consider the client's diagnosis, needs, and abilities, but also his/her wheelchair configuration and environment. For example, the following scenarios can lead to reduced spatial awareness and navigation challenges:
How Long Does Blind Spot Sensor Training Take?
Clients as young as 7 years old, and clients with varying levels of cognition* have successfully used Braze Mobility systems. The system feedback was designed to be intuitive, with all feedback designed to clearly prompt the user to safely navigate the chair.
While most clients can learn how to use basic features of the system within minutes, some clients might need up to a month of training before they can navigate safely with the system. Our founder, Dr. Viswanathan, spent several years in academia working with individuals with cognitive impairment, and has designed training protocols based on her research and clinically validated wheelchair training and assessment tools. Contact us to access these guides or to collaborate with us on new training protocols!
If you are unsure if the client will be able to use the system, you can use our free BrazeView simulator and training app to determine whether the client is able to understand the feedback and execute the correct response even before trialling the Blind Spot Sensors - watch the video on the left for more info and download the app today!
*Our Blind Spot Sensors only provide the driver with information and do not control the wheelchair in any way. They should not be relied upon to prevent collisions.
Where Are The Blind Spot Sensors Used?
The Braze Blind Spot Sensors can be used to align clients in a doorway, allowing them to back through while ensuring they are at an equal distance from both walls.
The Braze Blind Spot Sensors has been used to help clients navigate through tight spaces, such as kitchens and bathrooms. The feedback helps the client ensure that they are centred in the space, and increases their confidence while navigating in enclosed spaces.
The Braze Blind Spot Sensors have also been used for accessing public transportation, such as navigating onto and off of busses and streetcars.
Other use cases include:
- Getting on and off elevators is another activity of daily living made easier with the Braze Blind Spot Sensors. If the client drives forwards onto an elevator, and does not have enough room to turn around, the feedback can be used to determine when the doors are fully open, and then used to position the wheelchair in the doorway to back-out easily.
- For people with decreased hearing, or who are easily startled by people coming up behind them, Braze Blind Spot Sensors can be used to alert the person that someone is coming up behind them.
- For people who often take public transportation or travel through densely populated areas and carry backpacks on the back of their seat, the Blind Spot Sensors can be used to make sure they know if someone is behind them to help them protect their belongings from theft.
- For clients that have difficulty seeing their feet, Braze Mobility Echo Head sensors can be placed under foot rests to alert them when they are getting too close to objects.
What Are The Benefits Of The Blind Spot Sensors?
Independence - Often backing up requires the assistance of another person to avoid collisions. With the Braze Mobility blind spot sensor systems, the user is able to know what is behind them independently.
Confidence - Many of our clients report that before the Braze system, they had difficulty navigating in public, which led to embarrassment and/or safety concerns like knocking into shelves at department and grocery stores and running into children, other people, or strollers. After using the Braze Mobility system, they had the confidence needed to engage with the community knowing they had the information needed to avoid embarrassing and potentially hazardous situations.
- Increased access to power mobility for some clients - For clients on the borderline of not being able to operate their power mobility device, our blind spot sensors may provide them with the information needed to continue to use their power mobility device such as helping them learn the footprint of their chair. Our clients have said they used the system heavily inside their house when they were first prescribed their chair, and now primarily use it in unfamiliar spaces.
- Easy to use and install - All feedback was designed to be intuitive and easy to understand. They can be installed without the use of tools or any permanent modifications to the chair (Go-Pro style adhesive mounts that "click and stick"). These systems operate completely separate from the wheelchair and do not control the chair in any way. Resources to help clients use the product are available, including videos on recommended use, information packages and a training app. Often, therapists and clients are able to install and use the system without additional technical support, but we are always more than happy to guide you through it!
