Drawing Assist System with Focusing on the Velocity of Involuntary Movement
نویسندگان
چکیده
Creative activities such as painting and music are one source of satisfaction and fulfillment for people with disabilities. However, some individuals with a disability cannot satisfactorily enjoy such activities because of involuntary movement or spasms. In this study, we developed a drawing assist system for patients with cerebral palsy of the tension Athetosis type. We designed a variable filter to attenuate involuntary movement on the basis of the behavioral characteristics of the velocity component with respect to involuntary movement. We verified that it could support patients with such physical disabilities of weak

Optimization of parameters of Anti lock Braking System for use in deep drawing
A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

متن کاملThe movement disorder of Nicolas Poussin (1594-1665) [historical article].
Nicholas Poussin (1594–1665) is a key figure in the classic tradition of European visual art. From around 1630 onward his drawings develop a shaky quality, and in a letter dated 1650 he says “le tremblement de mes membres augmente comme les ans.” In the absence of detailed evidence, Poussin’s movement disorder has been variously ascribed to Parkinson’s disease or to neurosyphilis. A retrospecti...
متن کاملThe law relating the kinematic and figural aspects of drawing movements.
Considerable evidence exists that the velocity of execution of handwriting and drawing movements depends on some global metric properties of the movement (size, linear extent etc.). Recent experiments have demonstrated that the instantaneous velocity also depends on the local curvature of the trajectory, that is, on the differential geometrical properties of the movement. In this paper we inves...
متن کاملبررسی تغییرات الگوی کنترل حرکت ستون فقرات کمری بهدنبال افزایش مقاومت: مطالعه کلینیکی
Background: Joint trauma and injury are the most common causes of dynamic instability. Dynamic instability has a great effect on the lumbar spine, due to its three-dimensional motions. The greatest amounts of compression and shearing force are imposed at the points of maximum torque and velocity. The changes in these phase angles upon bearing various loads can cause some pathologic conditions. ...
