This is a meal-assistance device developed to help users with hand tremors, such as those caused by Parkinson’s disease or essential tremor - eat more comfortably. It is designed to detect the user’s tremors inside the handle and compensate for the movement in the opposite direction, ensuring the spoon head maintains a stable position. While naturally following the user’s intentional movements during meals, the device selectively reduces only irregular hand tremors, minimizing the inconvenience of spilling food and enabling users to eat more independently. Additionally, by utilizing a 3D-printing-based manufacturing process, production costs have been reduced compared to existing, high-priced imported assistive tableware, and the design can be modified or customized to suit the user’s specific characteristics and needs.

This assistive device was developed to protect the hands of people with disabilities and seniors who use electric wheelchairs from the elements during outdoor activities and to facilitate safe joystick operation. Neoprene and PVC materials were used to provide cold-resistant and waterproof protection, and the soft materials enhance safety against external impacts. It can be securely attached to the joystick using straps and mounting parts, and is designed for easy attachment and removal while maintaining joystick operability. It protects the user’s hands from external elements such as rain, snow, and cold, while supporting more convenient and stable operation of the electric wheelchair.

This assistive device was developed to help people with physical disabilities and older adults who have difficulty with rotational arm movements or muscle control operate a vehicle’s steering wheel. It features a handle, wrist support, and wrist strap to provide stable support for the hand and wrist, allowing the user to operate the steering wheel using the edge of the hand or the palm. The device is designed with a rotating mechanism at the bottom of the wrist support, allowing it to move naturally during steering, and it can be used with either the right or left hand. By supporting stable steering control tailored to the user’s physical characteristics and driving posture, it helps improve driving convenience and independence.
