We examined the strengths and weaknesses of three diverse scroll control modalities for photo browsing on personal digital assistants (PDAs). This exploration covered nine alternatives in a design space that consisted of three visual interfaces and three control modalities. The three interfaces were a traditional thumbnail layout, a layout that placed a single picture on the screen at a time, a...

The walk-through FogScreen has become very popular and famous during recent years. It is an immaterial projection screen that consists of air and a little humidity, and enables high-quality projected images in thin air, as well as many new applications. In this paper we describe a new extension, the interactive FogScreen, which turns it into a computer touch screen.

Temporal intensity flicker is a common artifact in old film sequences. Removing disturbing temporal fluctuations in image intensities is desirable because it increases both the subjective quality and, where image sequences are stored in a compressed format, the coding efficiency. We describe a robust technique that corrects intensity flicker automatically by equalizing local frame means and var...

Chronic aspirin ingestion in childhood is not uncommon, often goes undetected, and may cause serious anaemia from occult blood loss. Five cases are described.

BACKGROUND To improve effectiveness of future screen behaviour interventions, one needs to know whether an intervention works via the proposed mediating mechanisms and whether the intervention is equally effective among subgroups. Parental regulation is identified as a consistent correlate of screen behaviours, but prospective evidence as well as the mediation role of parental regulation is lar...

As touch-screen mobile phones pour into the market, demands for reusing existing mobile applications by adding a touch-screen UI are increasing. In order to service an existing application without a touch-screen UI to touch phones, an on-screen keyboard that implements a virtual keyboard on the touch screen is needed. On-screen keyboards are particularly convenient to use on small mobile phone ...

Original scientific paper In this article, we present the control framework and services scenarios of provisioning N-Screen services in interactive digital signage. Digital Signage provides a variety of high-resolution content and information displays at different public places and events. Provisioning N-Screen services in interactive digital signage enables the service providers to provide con...
