This study compares five input devices (mouse, mousepen, traekball, stylus, and touchscreen) on a series of goal-directed tasks using a drawing program. Striking performance differences are found for the touchsereen when compared with a previous study using a standard, isolated, laboratory task. The study also looks at the impact of device to screen mapping(More)
This study compares seven input devices (mouse, touchsereen, two trackba.lls, mousepen, touchp@ and joystick) performing a star tracing task. Along with the device comparisons, the diffemtce between moving with the selector button pressed (dragging) or with the button released (pointing) is examined. Recent work has found that dragging is slower and more(More)
The purpose of this work is to evaluate changes in temperature of one-piece titanium implant surface during the setting of acrylic resin temporary crowns and to correlate thermal changes to implant diameter. Thirty-three one-piece implants (ARRP, Alpha-Biotec) were divided into 3 groups according to diameter size (G1=3 mm, G2=3.3 mm, G3=3.6 mm). Implants(More)
