Problem & opportunity

Addressing motivation in stroke rehabilitation

Stroke patients lose motivation to continue hand therapies as they are long and tiring. MIDAS addresses this issue by helping patients stay motivated through its multi-sensorial approach.

Physical design

Mimicking natural finger movement

The exoskeleton uses a finger-link system that is powered by a motor to move the fingers.

Designing for comfort and wearability

The exoskeleton is 3D printed using strong and lightweight PLA, and coated with allergy-free silicon for comfort. The device is secured onto the hand with Velcro straps for adjustable sizing.

Olfactory design

Leveraging scent for relaxation

Bergamot and lemon scent mists are released to create a relaxing rehabilitation experience.

VR game design

Integrating all components through gameplay

A lemon-juicing VR game combines all the components for a multi sensorial experience.

Soothing spaces for relaxed rehabilitation

Natural environments and earthy interiors were shown to create a calming experience.

User testing

Participant demography

MIDAS was tested on stroke patients to validate the concept and evaluate its effectiveness.

Testing procedure

An incremental implementation was adopted where a component was added in each session. The goal was to validate whether the new component positively influenced motivation levels among stroke rehabilitation patients.
