Cambridge Researchers Develop Robotic 'Third Thumb' Enhancing Human Dexterity

A study shows people can quickly adapt to using an extra thumb, highlighting potential for accessibility and motor augmentation.

The Third Thumb is a 3D-printed prosthetic controlled by foot sensors, enhancing the hand's capabilities.
Nearly 600 participants, aged 3 to 96, successfully used the thumb within one minute of instruction.
The device allows users to perform complex tasks, such as opening bottles and manipulating objects, with ease.
No significant differences in performance were found between genders or handedness, though older adults showed some decline.
Researchers emphasize the importance of inclusive design to ensure accessibility for diverse populations.
