By Matthias Bezold

Adaptive Multimodal Interactive Systems introduces a common framework for adapting multimodal interactive platforms and contains a close dialogue of every of the stairs required for variation. This ebook additionally investigates how interactive platforms could be stronger when it comes to usability and person friendliness whereas describing the exhaustive person exams hired to guage the awarded approaches.

After introducing basic thought, a wide-spread strategy for person modeling in interactive platforms is gifted, starting from an statement of uncomplicated occasions to an outline of higher-level person habit. variations are awarded as a collection of styles just like these identified from software program or usability engineering.These styles describe habitual difficulties and current confirmed recommendations. The authors contain a dialogue on whilst and the way to hire styles and supply assistance to the process fashion designer who desires to upload adaptivity to interactive platforms. as well as those styles, the booklet introduces an model framework, which shows an abstraction layer utilizing Semantic net technology.Adaptations are carried out on most sensible of this abstraction layer by means of making a semantic illustration of the difference styles. The styles hide either graphical interfaces in addition to speech-based and multimodal interactive systems.

Inhabited Information Spaces Living with your Data

In an period while expanding numbers of individuals are accomplishing study and interacting with each other in the course of the web, the research of ? Inhabited info areas? is aimed toward encouraging a extra fruitful trade among the clients, and the electronic info they're having access to. Introducing the hot and constructing box of Inhabited details areas, this ebook covers all kinds of collaborative structures together with digital environments and newer recommendations reminiscent of hybrid and augmented real-world structures.

Digital Ecosystems

This publication constitutes the completely refereed post-conference court cases of the 3rd overseas convention on electronic Eco-Systems, OPAALS 2010, held in Aracaj? , Sergipe, Brazil in March 2010. The papers conceal themes from Social technology, machine technological know-how and from traditional technological know-how. those contain social networks, social applied sciences, electronic ecosystems, wisdom administration, context-aware scenario and electronic ecosystems, Lie team research, positive dynamical areas, and interplay computing.

Multimodal User Interfaces: From Signals to Interaction (Signals and Communication Technology)

The place multimodal sign processing meets multimodal human machine interplay. .. sign Processing (SP) and Human-Computer interplay (HCI), extremely popular clinical parts, are introduced jointly to supply ideas to a sequence of serious demanding situations within the box of multimodal interfaces. concentration is on multimodal interfaces that reply successfully to speech, gestures, imaginative and prescient, haptics and direct mind connections making the most of fresh advancements in either HCI and SP.

Semantic Models for Adaptive Interactive Systems

Offering insights into methodologies for designing adaptive structures according to semantic info, and introducing semantic types that may be used for construction interactive structures, this ebook showcases a few of the purposes made attainable by way of semantic types. Ontologies might increase the sensible insurance of an interactive method in addition to its visualization and interplay functions in a number of methods.

Example text

It employs an architecture called Jaspis. The system consists of managers, agents, and evaluators. Managers take care of specific components, for instance a dialog manager or a presentation manager. Agents handle (possibly very specific) situations, such as speech recognition errors. Different agents implement different strategies for the same situation and evaluators select among the available agents. The advantages of the agent-based approach are a high degree of flexibility and the possibility to implement different strategies and select among them at runtime.

The individual observations that are used to infer the user’s goal are uncertain. g. when certain observations are part of different plans. Moreover, users tend to work on different tasks in parallel. Third, plan recognition algorithms have to scale up in large domains with plan libraries that contain numerous plans a user possibly works on. In this work, we introduce an approach for adaptive interactive systems that employs a technique called task modeling (Patern`o, 2001). It describes the user-system interaction by means of tasks, which define possible user actions without speculation about the user’s intentions.

These algorithms may be implemented within the user modeling framework presented in this work. The selection of the algorithms depends on the requirements of a specific interactive system. We present a number of user modeling algorithms that we developed or adapted for adaptive interactive systems in Chapter 3. 2 Plan Recognition and Task Models Plan recognition is the process of observing user actions and determining the goal a user tries to accomplish. A plan represents the order of actions required to reach that goal.
