Who doesn’t love the challenge of solving a puzzle? Jigsaw puzzles are a popular hobby for all ages and have been an important tool in a child’s physical, cognitive and emotional development. Children can develop physical skills such as better hand/eye coordination; cognitive skills such as shape recognition, memory, and problem solving; and emotional skills such as setting goals and patience by completing puzzles. But what if you are a visually impaired or a blind parent? How can you help your child to accomplish this important developmental task?
Puzzle Solving Toolkit
At IBM Research – Ireland our team built a 3D computer vision driven task completion prototype called the Puzzle Solving Toolkit which interacts with visually impaired users to guide them in solving a jigsaw puzzle in a natural and intuitive way. We achieved this by providing a combination of computer vision algorithms and Watson services.
Our toolkit recognizes the puzzle pieces via a camera input and computes the best strategy for solving the puzzle. The system interacts with the user by leveraging Watson Speech to Text and Text to Speech services to communicate the necessary instructions about which piece to pick up next and also adapt to user’s feedback.
Watch our video where we explain how our Puzzle Solving Toolkit prototype works. In the video we also share additional research projects being developed by our team on Indoor PositioningSystems and Visual Recognition Systems.
Components of the toolkit
We utilize a head-mounted Intel 3D camera as video input and microphone/speaker to achieve natural human-computer interaction. The video input is fed to a deep learning pipeline, which identifies the puzzle pieces in a given scene and matches them to the original image of the puzzle. Upon completion of the pipeline, the core puzzle solving algorithm computes the solution of the puzzle and coordinates the instructions that need to be communicated to the user to successfully complete the puzzle.
The core puzzle solving algorithm and the deep learning pipeline are executed in a Nvidia TK1 board and leverage the computational speed of its GPUs. This demo unveils the capabilities we can provide in assisting visually impaired people to execute simple everyday tasks by bringing sophisticated AI algorithms together with advanced hardware.
With our toolkit we could envision helping, for example, visually impaired parents to guide their children in completing collaborative learning tasks. Our research can bring real-time, context-specific cognitive analytics to the edge, in tandem with deep device specialization and sensory augmentation, to transform the human experience.
Performing an everyday task such as cooking, navigating an indoor/outdoor environment, or attending a meeting at work is quite simple for most people. However, approximately 285 million visually impaired and 39 million blind people face an enormous challenge in accomplishing these daily tasks.  With the rapid convergence of hardware equipped with powerful sensors and 3D computer vision algorithms, we are now able to repurpose IoT devices and create AI-powered assistive technologies that naturally interact, using cognitive Watson services, to provide blind and visually impaired people with more independence. The spectrum of possible applications is endless, and we’re looking to enable people to accomplish more complex and challenging everyday tasks at a rapid pace.
The goal of our research is to help people maximise their full potential, accomplish more, and have a better quality of life. We will continue to enhance our prototypes, combined with the cognitive capabilities of Watson, to bring visually impaired people closer to complete autonomy.

Patenting is my passion and inclusion is my responsibility as an inventor. We should always think about how we can include all of the population in the technology we create. Invention and inclusion work very well together, as they can work in both directions. Together, we can invent to improve lives and make this world […]
About a month ago, I was “temporarily disabled” – I could not move without severe abdominal pain. I was diagnosed with appendicitis and had to undergo emergency surgery to remove the offending organ because it had enlarged to roughly threefold the average size. During the recovery, I was bedridden and under the constant care of […]
After spending my sophomore and junior years working on assistive technology projects with Northwestern University’s Inclusive Technology Lab, the opportunity to explore accessibility research at IBM was an exciting introduction into the industry. I worked on everything from server configuration to front-end development to design research interviews. This broad range of experience made for a […]
