This paper presents Smoothed Pointing, a velocity-based precision enhancing technique for remote pointing by means of absolute devices. After discussing the most recent related work concerning the problem of accuracy in remote pointing by handheld input devices, we introduce the distinctive features of the control-to-display ratio adaptation technique we have designed to: i) reduce the effect of both noise in input device signals and of hand tremors on the cursor stability; and ii) increase the accuracy of pointing when performed on large, high resolution displays. Moreover, we describe a 10 second calibration procedure to determine the filtering parameters, so as to free the user from a manual set up.

Abstract
This paper presents Smoothed Pointing, a velocity-based precision enhancing technique for remote pointing by means of absolute devices. After discussing the most recent related work concerning the problem of accuracy in remote pointing by handheld input devices, we introduce the distinctive features of the control-to-display ratio adaptation technique we have designed to: i) reduce the effect of both noise in input device signals and of hand tremors on the cursor stability; and ii) increase the accuracy of pointing when performed on large, high resolution displays. Moreover, we describe a 10 second calibration procedure to determine the filtering parameters, so as to free the user from a manual set up.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
