A study on Two-Dimensional Scrolling with Head Motion
نویسنده
چکیده
ABSTRACT This technical report presents an innovative interaction technique for simultaneously scrolling the content of a window in horizontal and vertical dimensions. Scrolling is controlled by head rotation via a non-intrusive computer vision system. Preliminary user studies show that this technique is easy to learn and provides substantial speed and accuracy advantages over scrollbar manipulation. Completion times for tasks including both scrolling and pointing are more than 30% faster for head-and-mouse than for mouse-and-scrollbar interactions.

Seismic Amplification of Peak Ground Acceleration, Velocity, and Displacement by Two-Dimensional Hills
There are valuable investigations on the amplification effects of the topography on the seismic response in the frequency domain; however, a question is that how one can estimate the amplification of time domain peak ground acceleration (PGA), peak ground velocity (PGV), and peak ground displacement (PGD) over the topographic structures. In this study, the numerical approach has been used for t...
متن کاملMechanical behaviour of motion for the two-dimensional monolayer system
In this paper we study the dynamics of the 2D-motion of a particle of monolayer. First we consider the usual physical time component and the plan manifold R2, having the polar coordinates. Then a geometric approach to nonholonomic constrained mechanical systems is applied to a problem from the two dimensional geometric dynamics of the Langmuir-Blodgett monolayer. We consider a constraint sub...

Introduction: Gluteal to tensor index indicates the electrical activition ratio of gluteal to tensor fasciae latae muscles, that the normalized electrical activity is used. The role of hip muscles in improving function and preventing injury is also considerable in the rehabilitation process of injury in patients with nonspecific chronic low back pain. This study aimed to compare the effect of c...
متن کاملThree dimensional numerical study on a trapezoidal microchannel heat sink with different inlet/outlet arrangements utilizing variable properties nanofluid
Nowadays, microchannels as closed circuits channels for fluid flow and heat removal are an integral part of the silicon-based electronic microsystems. Most of previous numerical studies on microchannel heat sinks (MCHS) have been performed for a two-dimensional domain using constant properties of the working fluid. In this study, laminar fluid flow and heat transfer of variable properties Al2O3...
