Engineers at the University of Waterloo, Canada, have pioneered a clever solution to aid individuals with neurodegenerative diseases in locating misplaced items.

Dementia, a condition characterized by cognitive decline, memory loss, and confusion, poses a significant challenge for both individuals suffering from it and their caregivers. The act of misplacing everyday objects can further exacerbate the difficulties faced by those with dementia, eroding their sense of independence and imposing additional burdens on those who care for them.

Driven by the need to address this issue, a team of researchers at the University of Waterloo has created a technology using artificial intelligence (AI) that could potentially transform the lives of individuals grappling with memory-related challenges.

The innovation is based on the "artificial memory" concept, an idea that imbues companion robots with the ability to remember and track objects.

The team began their exploration with a Fetch Robotics mobile manipulator robot, equipped with a camera that allows it to perceive its surroundings.

The critical breakthrough came through the implementation of an object-detection algorithm, enabling the robot to identify and track specific items within its visual field. This real-time tracking, recorded through stored video, forms the foundation of the robot's "episodic memory."

Through a user interface, individuals select the items they wish to track. Then, by simply entering the object's name, they can search for it through a smartphone app or computer. The robot, having meticulously recorded the object's movements, provides users with the last known location and time it was observed. This merging of AI and robotics not only alleviates the stress of searching for lost items but also bestows a sense of empowerment and autonomy upon its users.

The potential of this technology extends beyond the realm of dementia care. While its genesis was in addressing the challenges faced by those with cognitive impairments, the implications are far-reaching, the researchers said in a press release - everyone, at some point, has experienced the frustration of misplaced belongings. 

The project is covered in a paper published in the Association for Computing Machinery’s Digital Library and was presented at the recent 2023 ACM/IEEE International Conference on Human-Robot Interaction.
