objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

The paper presents the “Turntable”, a 3D input device for orienting objects using the non-dominant hand. The device supports two-handed manipulation by allowing the non-dominant hand to orient an object while leaving the dominant hand free to perform other actions. Two-handed input is a technique that can enhance the performance, simplicity and intuitiveness of CAD systems. These properties are...

PURPOSE This study aimed to compare the laterality, and its gender difference, of hand grip and elbow flexion power according to load in right hand-dominant individuals. METHODS The subjects were 15 healthy young males (age 22.1 +/- 0.7 y, height 171.3 +/- 3.4 cm, mass 64.5 +/- 4.1 kg) and 15 healthy young females (age 22.4 +/- 1.0 y, height 161.1 +/- 3.0 cm, mass 55.4 +/- 4.6 kg). Isotonic p...

We present a user interface for virtual environments that utilizes the non-dominant hand to provide haptic feedback to the dominant hand while it interacts with widgets on a virtual control panel. We believe this technique improves on existing prop-based methods of providing haptic feedback. To gauge the interface’s effectiveness, we performed a usability study. We do not present a formal compa...
