Affordable blind spot sensor solutions starting at $1,850 USD.

What Are Blind Spot Sensors?

The Braze Mobility blind spot sensors are a set of ultrasonic sensors that can be attached to any wheelchair, turning it into a "smart" wheelchair. They provide alerts to wheelchair users about objects in the environment using multimodal feedback (light, sound, and vibrations). Our sensors encourage safer navigation and independent driving to people who use wheelchairs.

Anyone who uses a wheelchair can use Braze's blind spot sensors, especially those who...

Have low vision, blindness or neglect

Have limited upper body or neck mobility

Have impaired attention

Use alternative drive controls and need to face forward

Drive in a tilted position, limiting their spatial awareness

Use accessories that block vision (e.g., backpack, oxygen tanks, communication devices, extended leg rests)

Our systems are often used by those with the following diagnoses:

Cerebral palsy (CP)
Traumatic brain injury (TBI)
Stroke
Vision loss or blindness

Spinal cord injury (SCI)
Multiple sclerosis (MS)
Amyotrophic lateral sclerosis (ALS)
Muscular dystrophy (MD)

Tight Spaces

Doorways and Elevators

Ramps

Crowded Areas

Public Transport

Braze's sensors can be set up anywhere around the wheelchair. When you request a quote, just let us know where coverage is needed! Our solutions are often used as backup sensors, proximity sensors, proximity alarms, orientation or mobility aids, and blind rehabilitation aids.

Wade Watts (Founder of Wheelchair Friendly Solutions) uses the sensors' visual/vibrational feedback to navigate through a tight spot. With the Braze sensors, Wade can safely back through his doorway and corridor.

Wade Watts demonstrates how he uses the blind spot sensors to navigate through tight spaces in his home, like the kitchen.

Steven Viera uses Braze's sensors to get on and off public transit.

How Do Blind Spot Sensors Work?

Braze's sensors do more than just alert people to objects around them.

Braze Mobility created the world's first patented blind spot sensors, which can be added to any wheelchair. The sensors enhance a wheelchair user's spatial awareness. Our sensors not only make safe drivers safer, but they promote independence.

1. Detecting Objects

The Sentina is Braze Mobility's main blind spot sensor and offers 180-degrees and 45-degrees of horizontal and vertical coverage, respectively.

Meanwhile, the Braze Echo Heads are Braze's additional sensors. Each Echo Head provides 45 to 50-degrees of targeted coverage.

Braze's blind spot sensors can detect objects at wide angles. These sensors can come together to create our kits.

2. Alerting Users With Light

When the blind spot sensors detect an object or obstacle, the Controller module will alert the user using intuitive lights.

The Controller has two modes of operation: a short range and a long range. Each mode consists of classifies obstacles in the warning or danger zones.

When an obstacle is in the warning zone, the Controller will emit a yellow light. Otherwise, obstacles in the danger zone will trigger the Controller to emit a red light.

The detection distances of the zones can be modified for the short-range and long-range modes, depending on a wheelchair user's needs.

3. Alerting Users With Sound And Vibrations

In addition to light feedback, the system can also alert the wheelchair user using sounds. The Controller will emit an audible "beep" sound in the danger zone.

Our clients may also purchase the Vibration Pads as an optional add-on feature. These modules provide directional feedback on the left, middle, or right side of a wheelchair user using vibrations. These modules can be attached to a wheelchair's armrest, seat cushion, or headrest.

4. Customizing User Experience

Braze Mobility's Blind Spot Sensor Kits

Meet the Braze Sentina Plus, our most popular kit!

The Braze Sentina and two Echo Heads make up the Braze Sentina Plus kit. The system offers both rear and peripheral coverage around the wheelchair.

When an object, wall, or person enters the vicinity of the sensor, feedback such as light, sound, and vibrations (an optional add-on) are sent to the wheelchair user.

Braze Mobility provides a collection of kits for a range of needs and lifestyles, with affordable solutions starting at $1,850 USD.

Blind Spot Sensors: A Smart Wheelchair Solution

Our patented sensors are also known as a smart wheelchair systems (SWCS). They are devices that are embedded (or added) to a person's wheelchair and are meant to enhance safety during wheelchair navigation. There are three kinds of SWCS devices: monitoring, alerting, and intervening technologies.
