HANDS|on: Supportive computer interface for home rehabilitation after stroke

By: Dasgelbem

Stroke is the leading cause… …of severe physical disability in the world. Frequently stroke survivors are left with partial paralysis… …on one side of the body. Fine motor skills can be relearned over time… …through repetitive physical exercises. However at home, …these often get neglected due to low levels of motivation.

"Hands|on" shifts therapy focus… …from monotonous training… …to meaningful task support. Stroke patients commonly enjoy… …and rely on PCs for various tasks. Using both hands, as one typically would, …would be desirable, but is not feasible. The gap between appears to be too wide to overcome. "Hands|on" offers individualized help: Whenever two hands are needed, …as in the case of dual key combinations, …typing with one hand is especially cumbersome. With the "Gesture|band" this gets easier.

It's simple to put on and quickly adjusted. It allows the use of simple gestures to trigger keys… …that would otherwise be hard to reach. For easier learning… …the gestures resemble their key counterparts: as hand up is "shift" and wave left is "backspace". The user can customize the presets anytime.

Visual and acoustic feedback makes life easier… …and encourages the user to go on. With a standard mouse, …accurate clicking without one's hand closing… …is difficult for stroke patients. Thanks to its special ergonomic shape, …the "Dual|mouse" encourages correct posturing of the hand.

Clicking is achieved simply by gently tilting the mouse. A single push with the thumb… …is all that is needed for a double click. Precise control of a mouse with the impaired hand is arduous. But with the "Dual|mouse" the healthy hand can assist. The mouse in the healthy hand is for better accuracy, …the "Dual|mouse" for higher efficiency. Additionally, the "Dual|mouse" filters unintentional movements. All this leads to the activation of the formerly passive hand.

To ensure that all settings reflect the patient's abilities, the therapist adjusts them during the weekly therapy sessions. Additional functions can be added and explained. Auxiliary settings can be switched off… …to further challenge the patient. "Hands|on" can therefore be completely integrated in ongoing rehabilitation. Making everyday life easier through support with training success as an added benefit.
