A framework is described that can assist game developers in using biometric (psychophysiological) methods while playtesting. Biometric methods can give developers a valuable additional window on the playtester’s experience. 1. THE USE OF BIOMETRICS When developing a game (or any other media product), is important to collect as much feedback from users as possible. After all, users will determin...

Goal modelling usually takes place during the early information systems development phase known as requirements engineering (RE). RE is a key factor for project success where a good tool support is necessary. Several goal-modelling tools exist and several approaches can be used to evaluate them. In this paper, we report on an experiment to evaluate two goal-modelling tools KAOS/Objectiver and i...

1.1 The structure of the model when there are more than two states We now describe how BioHMM is used when there are more than two underlying states. Most of the components of the model can be extended in an obvious way using the framework described in the Approach section of the paper. Because of the constraints imposed upon the parameters in the transition matrix, its structure is slightly co...

David Hume’s value theory—in particular, his theory of prudential value or self-interest—is rarely investigated in any depth. Though he makes a number of claims about what is in someone’s interest (including his discussion of the prudential value of the virtues in the second Enquiry1), there is very little material in Hume’s philosophic writing that yields a clear statement of his theory of wha...

In the last few years, researchers from the computer vision and image processing community have joined other research groups in searching for the bases of aesthetic judgment of paintings and photographs. One of the most important issues, which has hampered research in the case of paintings compared to photographs, is the lack of subjective datasets available for public use. This issue has not o...

The aim of the present study is to examine the relationships between Internet addiction, subjective vitality, and subjective happiness. The participants were 328 university students who completed a questionnaire package that included the Online Cognition Scale, the Subjective Vitality Scale, and the Subjective Happiness Scale. According to the results, subjective vitality and subjective happine...

Hearing problems such as hearing loss and susurrus aurium are said to improve with occlusal treatment, but few objective clinical reports have been published in the dental field. We looked at the effect of occlusal treatment and chewing instruction on hearing ability in five patients who had an occlusal disorder and the unilateral chewing habit. The following results were obtained: 1. Unilatera...

The kinematic sensitivity has been recently proposed as a unit-consistent performance index to circumvent several shortcomings of some notorious indices such as dexterity. This paper presents a systematic interval approach for computing an index by which two important kinematic properties, namely feasible workspace and kinematic sensitivity, are blended into each other. The proposed index may b...

Wireless sensor networks applications involve a position of inaccessible metropolitan vicinity enclosed by wireless sensor nodes (WSNs)-monitors environmental parameters like battle field surveillance, home applications like fire alarm, health monitoring, etc. Energy plays a vital role in Wireless sensor networks. So, we have to concentrate more on balanced energy consumption for maximizing the...
