Abstract: In this paper we present a novel integration of four remote collaboration modalities into an existing web-based medical data visualization framework: (1) visualization data haring, (2) camera view sharing, (3) data annotation haring and (4) chat. The integration of remote collaboration modalities was done for two reasons: for getting the second opinion on diagnosis or for getting a diagnosis from the remote medical specialist. We present an integration of these modalities and a preliminary evaluation by the medical expert. In conclusion we show that we are on the correct track of integrating collaboration modalities into the visualization framework.

The popularity of interactive surfaces is increasing because of their natural and intuitive usage. Adding 3D multi-point interaction capabilities to an arbitrary surface creates numerous additional possibilities in fields ranging from marketing to medicine. Interactive tables are nowadays present in numerous museums, schools and companies. With the advent of low-cost RGBD cameras, thee-dimensional surfaces are slowly emerging as well, attracting even more attention. This paper presents an affordable system for 3D human-computer interaction using a RGBD camera that is capable of detecting and tracking user’s fingertips in 3D space. The system is evaluated in terms of accuracy, response time, CPU usage, and user experience. The results of the evaluation show that such low-cost systems are already a viable alternative to other multi-touch technologies and also present interesting new ways of interaction with a surface-based interfaces.
Today we have successfully completed the HCI-IS 2014 conference. This was the 3rd event organised by the HCI.si community, an international conference on Human Computer Interaction in Information Society. The conference was organised in scope of Information Society Conference organised by Jožef Stefan Institute.

This paper describes the initial steps for the improvement of emergency call service. For instance, persons reporting an accident or similar event and the officer receiving the call are often under stress, which distracts the communication process and becomes a barrier to information transfer. We try to identify the main deficiencies when processing a received call and explore alternative ways of recording the main information content. In this regard we performed a usability test case study for assessing the efficiency of recording information either on a blank paper or in a prepared paper form. Implementation details of the usability test are described.

The paper describes an approach taken by a mobile application eDietetik for the presentation of health- related information that is not allowed to be provided as a health claim. In this case, a mobile device running the application interacts with consumers, translating health-related information in an understandable and unambiguous way. Moreover, it may present an interface between different human stakeholders (i.e. consumers and manufacturers, consumers and healthcare providers, manufacturers and policy-makers).
Audio alarming system for medical devices requires attention at some very specific segments. The clinical environment is full of disturbances and every alarm sound is not an exception. This paper presents some aspects of (audio) alarming within clinical environment and associated problems. Low power operation and limited resources for implementation are just on top of the problems related to the user experience. The presented solution is following the specific standards and is flexible enough to provide audio signals, which can be generated with small microcontroller. The described alarm generator was evaluated in laboratory and during clinical evaluation in real clinical environment with patients. The results are presented at the end of the paper.

This paper presents a low-cost website usability testing tool that records user’s mouse movement when performing search query on a web page. After a given time-out the web page is blurred and only some region around the mouse cursor remains transparent. The tool can be regarded as an automated version of the conventional squint test and can be used for the validation of the website design from the perspective of user cognitive load.
This paper presents a demo application for exploring the viability of using eye-gaze data for implicit human computer interaction in the context of photo collection management. The application takes advantage of eye-gaze data to augment interaction with photo collections and aid photowork tasks such as browsing, selecting and searching. It builds on the premise that the time a user spends viewing a photo is correlated with the user’s personal affinity for that photo.
