Assisting immersive virtual reality development with user experience design approach

2017

In our study we explored how to design a biography of a late Finnish artist as a VR experience. We conducted a development process assisted by user experience (UX) design methods, which increased the process efficiency, and resulted in a research prototype. Through previous research and our development process, we identified components affecting the user experience. These components are: Immersion, Presence, Disorientation, Sense of Control, Pleasantness, Exploration and Simulator Sickness. From our user study with 13 participants, we were able to draw implications that relate to these components. While the set of components could be incomplete or subject to change, shows that further resea…

Coupling dynamic simulation and interactive multiobjective optimization for complex problems: An APROS-NIMBUS case study

2014

Dynamic process simulators for plant-wide process simulation and multiobjective optimization tools can be used by industries as a means to cut costs and enhance profitability. Specifically, dynamic process simulators are useful in the process plant design phase, as they provide several benefits such as savings in time and costs. On the other hand, multiobjective optimization tools are useful in obtaining the best possible process designs when multiple conflicting objectives are to be optimized simultaneously. Here we concentrate on interactive multiobjective optimization. When multiobjective optimization methods are used in process design, they need an access to dynamic process simulators, …

Virtual Distance Lessons in Secondary School Teachers Continuous Education

2015

The paper provides an overview of organization principles of interactive distance teaching as well as its implementation for continuous education course for bilingual education teachers of 6 programme’s subjects. Distance teaching sessions were organized in 10 school’s computer classes. There are considered possible solutions for interactive distance learning classes. Lessons organization, based on the server’s remote session control is described. It is arranged participating teacher survey regarding usability of applied environment and made conclusions about appropriateness of developed approach.

""Flora Italiana Digitale": an interactive identification tool for the Flora of Italy

2010

The digital facilities of the second edition of Pignatti's "Flora d'Italia" are presented. A software, called FID (i.e. "Flora Italiana Digitale") will link together a random-access interactive identification tool, a thesaurus, synoptic tables and one template for each single species, including a distribution map (referred to the Italian regions), "ecograms", a text-box and up to 24 high-resolution colour images. The FID follows a "shareware phylosophy". All contents and images can be integrated and/or replaced over time, in order to continuously improve the diagnostic and qualitative performance of the utilities provided. Ideally, the community of users should interact on the web, so that …

Comparing reference point based interactive multiobjective optimization methods without a human decision maker

2022

AbstractInteractive multiobjective optimization methods have proven promising in solving optimization problems with conflicting objectives since they iteratively incorporate preference information of a decision maker in the search for the most preferred solution. To find the appropriate interactive method for various needs involves analysis of the strengths and weaknesses. However, extensive analysis with human decision makers may be too costly and for that reason, we propose an artificial decision maker to compare a class of popular interactive multiobjective optimization methods, i.e., reference point based methods. Without involving any human decision makers, the artificial decision make…

On Using Decision Maker Preferences with ParEGO

2017

In this paper, an interactive version of the ParEGO algorithm is introduced for identifying most preferred solutions for computationally expensive multiobjective optimization problems. It enables a decision maker to guide the search with her preferences and change them in case new insight is gained about the feasibility of the preferences. At each interaction, the decision maker is shown a subset of non-dominated solutions and she is assumed to provide her preferences in the form of preferred ranges for each objective. Internally, the algorithm samples reference points within the hyperbox defined by the preferred ranges in the objective space and uses a DACE model to approximate an achievem…

A Location Based Service for the production of interactive photographs

2010

Currently, photographs are an indispensable means for documenting and surveying objects and places, however, they have an inherent limitation due to a lack of identification data. Digital applications on a photograph could resolve this limitation. This paper, therefore, details the results of a research based on an innovative photographic system, with the purpose of identifying objects in digital photos. To carry out this procedure, this is achieved by partly utilizing a Location Based Service. The final product, obtained from the user in real time with a simple shot of the photo, constitutes a small information system, which enables the analysis of the images of places and objects in an in…

An ACT-R Based Humanoid Social Robot to Manage Storytelling Activities

2020

This paper describes an interactive storytelling system, accessible through the SoftBank robotic platforms NAO and Pepper. The main contribution consists of the interpretation of the story characters by humanoid robots, obtained through the definition of appropriate cognitive models, relying on the ACT-R cognitive architecture. The reasoning processes leading to the story evolution are based on the represented knowledge and the suggestions of the listener in critical points of the story. They are disclosed during the narration, to make clear the dynamics of the story and the feelings of the characters. We analyzed the impact of such externalization of the internal status of the characters t…
