Having an extra thumb on one hand could significantly boost manual dexterity, but wouldn’t that pose a challenge in learning to utilize it effectively? According to a groundbreaking study, findings suggest that a vast majority of people grasp the concept within just 60 seconds.
When British designer Danielle Clode unveiled the Third Thumb during her Masters graduate project at London’s Royal College of Art, it sparked widespread interest.
At the core of the device lies the 3D-printed articulated thumb, carefully secured to the user’s natural right-hand thumb, allowing for a mirrored configuration. A thin cable links the thumb to a compact wrist-mounted motor module, seamlessly connected via wireless communication to two discreetly positioned stress sensors, strategically placed under each user’s largest toe.
As the right-side sensor is subjected to pressure, the thumb exhibits lateral movement across the hand, while the left sensor’s tension prompts the digit to shift upwards towards the fingers. When toe stress intensifies, the thumb’s strike time draws near. When tension in the toes is released, the thumb naturally returns to its resting position.

Scientists at College Faculty London discovered the potential applications of the Third Thumb and reached out to Clode to explore integrating it into their research on physical enhancement. Within a short period, 20 volunteers had just five days to learn how to utilize the device, and were motivated to dedicate 2-6 hours each day to master it. While the analysis effectively demonstrated the cognitive impact of using the Thumb on exercise-related neural adaptations in the sensorimotor cortex, it falls short of illustrating its practical applications and potential for widespread utilization across diverse populations?
The prestigious new research from the University of Cambridge has finally been released.
With data primarily sourced from 2022, the general public has been encouraged to engage with the Thumb at the annual Royal Society Summer Science Exhibition. Within a five-day period, a total of 596 participants had just one minute to become acquainted with the machinery. Participants reportedly represented a diverse range of demographic backgrounds, spanning ages from three to 96 years old.

Despite a 60-second training session, all but four individuals were able to intentionally manipulate their thumb, excluding babies who lacked the necessary toe pressure, as well as those whose setups failed to align properly. Thirteen out of all contributors possess the extraordinary ability to manipulate objects using their Thumbs.
Taking issues a step further, the volunteers have been asked to undertake two distinct initiatives to enhance community engagement and foster greater social cohesion. particular duties after the one-minute orientation. Individuals tasked with this challenge primarily utilize their thumb to select pegs from a pegboard and transfer as many as possible into a basket within 60 seconds. Three hundred thirty-three contributors have taken action.
Utilizing the thumb to initiate and manipulate the tool was a crucial step in this process. together with the hand To swiftly select and position an assortment of foam items with diverse designs and dimensions, aiming to relocate as many as feasible within a 60-second timeframe. A total of 246 individuals successfully completed the training.

Research revealed a surprising lack of disparity in efficiency between male and female users, as well as left- and right-handed individuals, despite the fact that the innovative Third Thumb device is specifically designed for right-handed use.
While there was limited disparity in performance between younger and older adults, a notable decline in efficiency was observed among the older subgroup as age progressed. The decline in technology proficiency among seniors might have stemmed from the natural degradation of sensory-motor and cognitive functions, or it could simply be that older individuals are generally less familiar with modern technology.
The potential development of the Third Thumb technology could not only enhance the abilities of able-bodied individuals but also significantly benefit those with reduced manual dexterity, opening up new possibilities for greater independence and autonomy.
Augmenting expertise means forging a novel connection between humans and knowledge, transforming software into an integral part of our physicality, remarks Clode, currently collaborating with the lead scientist at the University of Cambridge’s esteemed research laboratory. Tamar Makin. Considering the diversity of human forms, it is crucial that wearable technology’s design phase prioritizes inclusivity from the outset. It’s essential that these devices are accessible and practical for a diverse range of users.
A recent study published in a peer-reviewed journal has been examined. . Check out the Third Thumb in action by viewing the accompanying video.
