Magnification for Distance Pointing

چکیده
We see currently the trend of having larger and larger displays in our living rooms and that more and more computer oriented applications which are usually controlled by a mouse are displayed by them. Examples for the latter are web browsing, picture browsing, chatting and email. This leads to two problems. Firstly, most applications and web pages are not designed for situations in which the user is sitting in a relative large distance from the display. The user is therefore often not able to read the text, to interact easily with buttons or to click on hyperlinks. Secondly, it is not appropriate to use the mouse as the input device as flat surfaces are typically not in reach when sitting on the sofa in the living room. This paper investigates firstly whether direct pointing would be a suitable interaction concept and secondly whether the usage of magnifiers helps the user when interacting from a distance. The paper reports a study comparing three different magnification techniques for direct pointing interaction with remote screens. The results provide clear evidence for the advantages of such interactions, especially when combined with linear and Fish Eye magnifications.

The Pointing Errors in Optic Ataxia Reveal the Role of “Peripheral Magnification” of the PPC
Interaction with visual objects in the environment requires an accurate correspondence between visual space and its internal representation within the brain. Many clinical conditions involve some impairment in visuo-motor control and the errors created by the lesion of a specific brain region are neither random nor uninformative. Modern approaches to studying the neuropsychology of action requi...
متن کاملDesign of an Imaging Telescope with Variable Magnification and Imaging Distance
Vacuum spatial filters, used to control beam quality and remove unwanted high spatial frequency noise from amplified beam pulses, mostly rely on two-lens imaging telescopes with no flexibility in magnification and imaging distance unless the lenses themselves are replaced. New three-lens and four-lens imaging telescopes facilitate adjustable beam magnification and imaging distance by altering o...

Microlensing uses gravitational lensing of individual stars to detect planets. In a microlensing event, the light from one star, the “source”, is magnified by the gravitational field of another star, the “lens”. A microlensing event occurs when the paths of two stars on the sky pass very close to each other, typically less than 1′′ [An arcsecond (′′) is 1/3600th of a degree. It may be further d...
