Smart Canes for the Visually Impaired: Innovative Startups

The Evolution of the White Cane for Modern Use

Despite significant advancements in technology aimed at improving accessibility for individuals with blindness or visual impairments, the traditional white cane has seen limited innovation.

WeWalk: A Traditional Approach with a Technological Twist

WeWalk, a company originating from London, presents a contemporary take on the classic white cane. Visually, its products closely resemble standard folding canes, with the primary difference being a more substantial handle.

Currently, WeWalk offers two distinct models: the Smartcane 2, priced at $850, and the Smartcane+ 2, available for $1,150. The key difference lies in the inclusion of a voice-activated assistant within the Smartcane+ 2 – a potentially crucial feature for visually impaired individuals who are mobile.

Key Features of the WeWalk Smartcanes

• Obstacle detection at ground level.
• Capability to identify overhead obstructions.
• Wireless connectivity to smartphones (iPhone/Android).
• Voice-guided walking directions via an integrated speaker.
• Tactile button interface for smartphone interaction.

The cane connects wirelessly to a smartphone, delivering walking directions through a built-in speaker. Buttons on the handle provide a tactile method for controlling the phone, addressing a common limitation of smartphones for visually impaired users.

Glidance: Introducing an Autonomous Mobility Aid

Glidance, a startup based in Washington state, represents a newer presence in this field. Their product, named Glide, is described as an “autonomous, self-guided mobility aid,” essentially a robotic device.

Unlike the conventional cane shape, Glide features a handle mounted on a wheeled base. The system is currently in a soft launch phase following an initial preorder period, with a price of $1,500 ($1,799 including an annual subscription).

Glide's Advanced Technological Capabilities

Glide utilizes a pair of stereo-depth cameras and employs a more complex technical approach. Beyond obstacle avoidance, it provides alerts for approaching doors, elevators, stairs, and curbs.

Furthermore, the system temporarily immobilizes at intersections to ensure safety from oncoming traffic. The company anticipates full product shipment within approximately one year.

Glidance has successfully secured $1.5 million in pre-seed funding and is presently finalizing a $5 million seed round.
