In search of suitable methods for measuring the affective state of video-game players, this study investigates the hypothesis that the player's state of arousal will correspond with the pressure used to depress buttons on a gamepad. A video game was created that would detect the force of each button press during play. It was found that as the difficulty level of the game increased, players would hit the gamepad buttons significantly harder.
It has been possible to digitize analogue images for a number of years--either by the use of a still frame from a video camera, or by scanning a continuous-tone photograph--and to produce output in either print or transparency form, or with the captured image as part of, say, a computer-generated teaching slide. The quality has until now been less than adequate in terms of overall resolution and colour fidelity. It is only recently that true digital imaging has allowed the medical photographer to examine the mechanics of the production of high-quality clinical images and to see if this technology can provide a viable alternative to conventional silver imaging in terms of resolution, colour accuracy, speed, economy and overall usability. This article describes the short-term use of the Kodak Digital Camera System (the DCS) in the clinical studio and assesses the factors stated above.
A previous two-part article by Simon Brown described the acquisition, editing, compression and initial storage of digital images taken in the clinical studio. Due to the higher-than-expected demand for this clinical service, additional factors had to be considered when dealing with large numbers of images. These included storage on writable compact disc (CD) drives and a system for retrieving images from these devices which was flexible enough to handle the requirements of different specialities and be usable by all medical illustration staff.
Following Part 1 of this article in the previous issue in which the technical aspects of the system were explored, Part 2 looks at the use of the digital camera system in the clinical photographic studio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
