Synopsis

This report covers a University of Massachusetts Amherst study that won a Best Paper Award at CHI 2024, the leading conference for human-computer interaction research, on how to design robot guide dogs that blind people would actually use. Researchers interviewed and observed 23 visually impaired guide dog handlers and five trainers, then analyzed the themes to define what an effective robotic guide must do. A key finding is that handlers do not want a self-driving robot: the person plans the route while the dog handles nearby obstacles, with trust and shared control shifting over time. The work matters because guide dogs are scarce, costly to train and not suited to people with allergies or limited ability to care for an animal, so practical robot guides could widen independent mobility for many more people with vision loss.*

At a Glance

• 1 - Training a guide dog alone can cost around $40,000.
• 2 - About 90 percent of participants raised battery life as a concern.
• 3 - Handlers asked for help with overhead obstacles and with finding the right bus and a seat.
• 4 - The team gathered 2,000 minutes of audio and 240 minutes of video, which they plan to analyze further.

Topic Definition

Guide Dog Robot

A guide dog robot is a mobile robot, often built on a four-legged or wheeled platform, designed to lead a blind or visually impaired person safely through their surroundings in a similar way to a trained guide dog. It typically uses cameras and other sensors to detect obstacles, curbs and doors, and a handle or harness to communicate direction and stops to the user, who keeps overall control of the route.

Overview

What features does a robotic guide dog need?

Ask the blind, say the authors of an award-winning paper. Led by researchers at the University of Massachusetts Amherst, a study identifying how to develop robot guide dogs with insights from guide dog users and trainers won a Best Paper Award at CHI 2024: Conference on Human Factors in Computing Systems (CHI), the leading venue for human-computer interaction research.

Guide dogs enable remarkable autonomy and mobility for their handlers. However, only a fraction of people with visual impairments have one of these companions. The barriers include the scarcity of trained dogs, cost (which is $40,000 for training alone), allergies and other physical limitations that preclude caring for a dog.

Robots have the potential to step in where canines can't and address a truly gaping need - if designers can get the features right.

"We're not the first ones to develop guide-dog robots," says Donghyun Kim, assistant professor in the UMass Amherst Manning College of Information and Computer Science (CICS) and one of the corresponding authors of the award-winning paper. "There are 40 years of study there, and none of these robots are actually used by end users. We tried to tackle that problem first so that, before we develop the technology, we understand how they use the animal guide dog and what technology they are waiting for."

The research team conducted semistructured interviews and observation sessions with 23 visually impaired dog-guide handlers and five trainers. Through thematic analysis, they distilled the current limitations of canine guide dogs, the traits handlers are looking for in an effective guide and considerations to make for future robotic guide dogs.

One of the more nuanced themes that came from these interviews was the delicate balance between robot autonomy and human control.

"Originally, we thought that we were developing an autonomous driving car," says Kim.

They envisioned that the user would tell the robot where they want to go and the robot would navigate autonomously to that location with the user in tow.

This Is Not The Case

The interviews revealed that handlers do not use their dog as a global navigation system. Instead, the handler controls the overall route while the dog is responsible for local obstacle avoidance. However, even this isn't a hard-and-fast rule. Dogs can also learn routes by habit and may eventually navigate a person to regular destinations without directional commands from the handler.

"When the handler trusts the dog and gives more autonomy to the dog, it's a bit delicate," says Kim. "We cannot just make a robot that is fully passive, just following the handler, or just fully autonomous, because then the handler feels unsafe."

The researchers hope this paper will serve as a guide, not only in Kim's lab, but for other robot developers as well.

"In this paper, we also give directions on how we should develop these robots to make them actually deployable in the real world," says Hochul Hwang, first author on the paper and a doctoral candidate in Kim's robotics lab.

For instance, he says that a two-hour battery life is an important feature for commuting, which can be an hour on its own.

"About 90% of the people mentioned the battery life," he says. "This is a critical part when designing hardware because the current quadruped robots don't last for two hours."

These are just a few of the findings in the paper. Others include: adding more camera orientations to help address overhead obstacles; adding audio sensors for hazards approaching from the occluded regions; understanding 'sidewalk' to convey the cue, "go straight," which means follow the street (not travel in a perfectly straight line); and helping users get on the right bus (and then find a seat as well).

The researchers say this paper is a great starting point, adding that there is even more information to unpack from their 2,000 minutes of audio and 240 minutes of video data. Winning the Best Paper Award was a distinction that put the work in the top 1% of all papers submitted to the conference.

"The most exciting aspect of winning this award is that the research community recognizes and values our direction," says Kim. "Since we don't believe that guide dog robots will be available to individuals with visual impairments within a year, nor that we'll solve every problem, we hope this paper inspires a broad range of robotics and human-robot interaction researchers, helping our vision come to fruition sooner."

Ultimately, Kim understands that robotics can do the most good when scientists remember the human element. "My Ph.D. and postdoctoral research is all about how to make these robots work better," Kim adds. "We tried to find an application that is practical and something meaningful for humanity."

Frequently Asked Questions

NOTE: Researched FAQs by Disabled World (DW)

How long does it take to train a guide dog?

Most guide dogs spend about two years being raised and trained before they are matched with a handler, followed by several weeks of training together.

Are guide dogs free for blind people?

Many guide dog schools in the United States provide dogs and training at no cost to the handler, funded by donations, though waiting lists can be long.

Can a robot guide dog go anywhere a guide dog can?

Laws giving guide dogs access to public places do not automatically cover robots, so access rules for robotic guides are still unclear.

What is CHI?

CHI is the ACM Conference on Human Factors in Computing Systems, the largest yearly meeting for research on how people interact with technology.

What other navigation tools do blind people use?

Common tools include the white cane, smartphone apps with GPS and audio directions, electronic travel aids that detect obstacles, and remote help services that connect users with sighted guides.

Why do handlers want shared control rather than full autonomy?

Handlers know their destination and the risks around them, and full autonomy can feel unsafe. Shared control lets the person decide the route while the guide manages nearby obstacles.

Would a robot guide help people with allergies to dogs?

Yes, that is one of the main reasons researchers are developing them, along with helping people who cannot meet the daily care needs of a dog.

When might robot guide dogs be available?

No robot guide dog is widely available yet. Researchers expect several more years of design and testing before any are ready for everyday use.

Insights, Analysis, and Developments

Editorial Note: Robot guide dogs have been studied for about 40 years without reaching everyday use, and this paper argues that the reason is simple: they were built around what engineers imagined rather than how handlers and dogs really work together. By starting with the people who would rely on the device, the UMass team has produced a design checklist covering control, sensing, battery life and public transport that other labs can use. The researchers themselves say robot guides are not a year away, and four-legged robots will need to become quieter, lighter and more durable before they can share sidewalks and buses. For now, guide dogs, white canes and navigation apps remain the main mobility tools, and blind users are best placed to judge any new option.*
