Abstract

In this paper, an enhancement of a web application design is presented. The aim was to modify the visual quality of the application in order to make it simple and visually more easy to understand, which consequently leads to improved user experience. The process of enhancement of user interface of the web application home page and subsequent web pages is based on different methods for establishing clear visual hierarchy of presented information, among them the methods of reduction, regularization and leverage. The web application to which the above principles were applied is Open Platform for Clinical Nutrition, which offers to users effective means for identifying their nutritional state and adjusting diet plans to their way of life and clinical state. Currently, the application has about 3000 active users.

Abstract

In this paper we present a web kiosk framework based on Kinect sensor. The main idea is to use the framework for creation of simple interactive presentations for informing, advertising and presenting knowledge to the public. The use of such a framework simplifies adaptation of existing web materials for presentation with the kiosk. We can also make use of touchless interaction for browsing through the interactive content, to animate the user and encourage her to spend more time browsing the presented content. We present the structure of the framework and a simple case study on using the framework as an interactive presentation platform and as an education resource. The developed framework has been used for presenting information on educational programs at Faculty of Computer and Information Science, University of Ljubljana.

HCI-SEE

Posted on by

The first event organised by hci.si was successfuly concluded as a workshop at the SouthCHI conference in Maribor. The whole conference took place at hotel Habakuk from the 1st to the 3rd of July 2013. The conference had broad international participation from the HCI community.

Three approaches from community members were presented at the workshop:

FingerScape: Multi-touch User Interface Framework

Posted on by

Intuitive human computer interaction (HCI) is becoming an increasingly popular topic in computer science. The need for intuitive HCI is fueled by the need for intuitive mastering and interaction with increasing complexity of software, amounts of data. Devices, where one or more users intuitively (e.g. with fingers) and simultaneously manage content are currently very rare, expensive (e.g. Microsoft Surface) and usually only provided as technology show-case.

An important advantage of such devices is the possibility of multi-user experience that enables additional ways of inter-user interaction. This makes this kind of systems suited for applications such as multimedia content viewing and browsing (e.g. in museums, galleries, exhibitions, …) and visualization of large quantities of information.

The goal of the project is creation of an open source platform that will ease the development of multi-touch multi-user (MTMU) enabled applications. No such freely available complete solution exists at this time. We believe that such a platform will increase the popularity and production of multi-touch systems as well as enable more rapid development of MTMU enabled applications.

Hardware

As a first step towards our goal we have set up a FTIR-based multitouch table to provide a hardware basis for the development of the platform.

Bootstrapping HCI-SI

Posted on by

With this blog we are starting a bootstrapping procedure of Slovenian HCI community. Our goal is to connect researchers from academic and industrial backgrounds and form a community.

First step is setting-up this blog as meaning of exchange and publication of activities in community.

Second step is organisation of HCI-SEE Workshop as part of SouthCHI conference which takes place in Maribor in mid 2013.
