The authors examined whether the nature of the opponent (computer, friend, or stranger) influences Spatial Presence, emotional responses, and threat and challenge appraisals when playing video games. In a within-subjects design, participants played two different video games against a computer, a friend, and a stranger. In addition to self-report ratings,(More)
To understand how implicit and explicit biofeedback work in games, we developed a first-person shooter (FPS) game to experiment with different biofeedback techniques. While this area has seen plenty of discussion, there is little rigorous experimentation addressing how biofeedback can enhance human-computer interaction. In our two-part study, (N=36)(More)
Traditionally, mobile media sharing and messaging has been studied from the perspective of an individual author making media available to other users. With the aim of supporting spectator groups at large-scale events, we developed a messaging application for camera phones with the idea of collectively created albums called Media Stories. The field trial at(More)
We investigated the emotional response patterns and sense of presence elicited by video games with different characteristics (i.e., Tetris, Super Monkey Ball 2, Monkey Bowling 2, and James Bond 007: NightFire) among 37 undergraduates. We also examined the moderating influence of the sensation seeking and self-forgetfulness traits on the responses.(More)
We examined emotional valence-and arousal-related phasic psychophysiological responses to different video game events among 36 young adults who played Super Monkey Ball 2 (Sega Corporation, Tokyo, Japan). Event-related changes in zygo-maticus major, corrugator supercilii, and orbicularis oculi electromyographic activity , skin conductance level, and cardiac(More)
The authors examined emotional valence- and arousal-related phasic psychophysiological responses to different violent events in the first-person shooter video game "James Bond 007: NightFire" among 36 young adults. Event-related changes in zygomaticus major, corrugator supercilii, and orbicularis oculi electromyographic (EMG) activity and skin conductance(More)
The authors examined phasic psychophysiological responses indexing emotional valence and arousal to different game events during the video game Monkey Bowling 2. Event-related changes in skin conductance, cardiac interbeat intervals, and facial EMG activity over corrugator supercilii, zygomaticus major, and orbicularis oculi were recorded. Game events(More)
FragMatch is a user-friendly Java-supported program that automates the identification of taxa present in mixed samples by comparing community DNA fragment data against a database of reference patterns for known species. The program has a user-friendly Windows interface and was primarily designed for the analysis of fragment data derived from terminal(More)
Personalization is a process that changes the functionality, interface, information content, or appearance of a system to increase its personal relevance to an individual. Personalization systems accommodate individual's needs and interests explicitly through changes and selections initiated by the user, and implicitly through automatic adaptation(More)
The authors examined the effects of suboptimally presented facial expressions on emotional and attentional responses and memory among 39 young adults viewing video (business news) messages from a small screen. Facial electromyography (EMG) and respiratory sinus arrhythmia were used as physiological measures of emotion and attention, respectively. Several(More)
