We consider the problem of defining the information leakage in interactive systems where secrets and observables can alternate during the computation. We show that the information-theoretic approach which interprets such systems as (simple) noisy channels is no longer valid. However, the principle can be recovered if we consider channels of a more complicated kind, that in Information Theory ar...

X and Y are random variables. Person P X knows X , Person P Y knows Y , and both know the joint probability distribution of the pair (X; Y). Using a predetermined protocol, they communicate over a binary, error-free, channel in order for P Y to learn X. P X may or may not learn Y. How many information bits must be transmitted (by both persons) on the average? At least H (XjY) bits must be trans...

We demonstrate several parallels between interactive verbal communication and graphical communication. Experiment 1 shows that through interaction partners’ graphical representations converge, and are refined, although degree of refinement is dictated by level of interaction. Experiment 2 shows that through interaction graphical representations lose their iconicity, taking on a more symbolic fo...

Daily interactive communications involve the processing of verbal and nonverbal emotional cues from auditory and visual stimuli. The encoding and decoding schemes of emotional speech, however, have not been fully investigated in an interactive communication framework. Therefore, the present research is concerned with the encoding and decoding process of emotional speech during interactive commu...

We consider the problem of defining the information leakage in interactive systems where secrets and observables can alternate during the computation. We show that the information-theoretic approach which interprets such systems as (simple) noisy channels is not valid anymore. However, the principle can be recovered if we consider more complicated types of channels, that in Information Theory a...

Despite technological, interaction and co-located collaboration advances on multi-touch interactive tables there is little or no knowledge of how people communicate around these surfaces. Communication is important as it acts as a tool for human to express themselves. Through communication we are able to share information, ideas and emotions; make decisions and build relationships with people. ...

We present many new results related to reliable (interactive) communication over insertiondeletion channels. Synchronization errors, such as insertions and deletions, strictly generalize the usual symbol corruption errors and are much harder to protect against. We show how to hide the complications of synchronization errors in many applications by introducing very general channel simulations wh...

T-learning —the provision of educational services over Interactive Digital TV— is regarded as a complement to e-learning solutions, whose scope is limited due to the digital divide. The increasing connectivity, together with the fact that IDTV users are no longer passive spectators, permits to start thinking on highly interactive services that support fluid communication among users and service...

Under the background of the new media era with the rapid development of interactive advertising, this paper used case study method based on the summary of the research of the communication effect of interactive advertising from both domestic and foreign academia. This paper divided interactive advertising into three types to examine ---interactive ads on official website, interactive ads based ...
