The aim of this research is twofold. Firstly, it analyzes how the two main features of Internet Protocol Television (IPTV), interactivity and personalization, influence both customers’ perceived performance and involvement with a web-based information service. Secondly, it studies whether personalization and interactivity improve customer purchase intentions of this service through IPTV. We dev...

Animated diagrams representing dynamic systems hold great potential for improving the way people learn. However, so far the literature failed to find clear benefits of animated diagrams. Consequently it is worthwhile to investigate conditions under which enhancement of learning occurs. In the present study interactivity of the display and spatial ability of learners were examined. Three modes o...

The study integrates web quality (system quality, information quality, and service quality), perceived interactivity (human-message, humanhuman), and web outcomes (web usage, web satisfaction, and web loyalty) to explore the ecommerce model of health websites. A survey of 1076 users of health websites was conducted to validate the proposed model. The findings show that web quality has significa...

This study investigated whether media interactivity would influence the short-term effects of violent content on audience aggression. The general aggression model, social cognitive theory, and character identification offered the theoretical framework. A random sample of 102 male college students were randomly assigned to one of three conditions: video game playing, recorded game-play watching,...

This draft CLASS (Collaboration in Language and Speech Science Technology) report discusses the market opportunities for natural interactive communication systems technologies. The vision of natural interactivity is presented and related to the idea of multimodal systems. The components of natural interactivity are presented. As natural interactive communication systems technologies are future ...

Interactivity is regarded as one of the core components of a successful Virtual Reality experience, and is promoted widely for its effectiveness, motivational impact, and significance for learning. The research described in this paper sets out to explore learner interaction in immersive Virtual Environments, focusing on the role and the effect of interactivity on learning and conceptual change....

In the triangle of coins problem coins are arranged to create a triangle pointing down and the solution involves moving a few coins to change its orientation. The task ecology can be designed such that participants can work on it in a low interactivity environment, maintaining a mental representation of simulated moves, or in a high interactivity environment, thinking with and through a physica...

This study tested a model of enjoyment of video games focused on three important predictors; interactivity, realism and spatial presence. In a large, randomized experiment (N = 257), players of traditional console games were compared with their counterparts playing on mobile devices. The hypothesized model included perceived interactivity, perceived reality and spatial presence, with enjoyment ...

Adaptive Playout is a solution in IP-based communication clients to compensate network issues using a dynamic receiver buffer. Whereas small buffers provoke loss artefacts due to delayed packets, large buffers result in high delay and loss of interactivity. Existing Voice over IP clients balance the trade-off between low delay and loss artefacts based on empirical values. Most often the degree ...

We conducted two experiments to explore how moderation, response rate, and message interactivity affected people’s intent to participate in a web-based online community. In our first experiment, 62 participants observed either a moderated or an unmoderated online community and answered questions about their intent to participate in the community. The participants who viewed the moderated commun...
