HCI-IS 2019 proceedings

human computer interaction in information society 2019

human computer interaction in information society 2019

Human-computer interaction in information society is a conference organized by the Slovenian HCI community. The purpose of the conference is to gather researchers, practitioners and students in the field and offer the opportunity to exchange experiences  and research results, as well as to establish contacts for future cooperation.

human computer interaction in in formation society 019

human computer interaction in in formation society 019

This year’s fourth reincarnation of the conference is, for the first time, organized by the newly established SIGCHI Chapter ACM Chapter Bled, which is partly a result previous
conferences. The growth of the HCI community in the region is also witnessed by the doubled number of contributions coming from all major higher education institutions in Slovenia and abroad.

The topics covered by the conference range from the more established ones, such as usability testing, visualization and design of graphical user interfaces to virtual and augmented reality, user interfaces in healthcare, automotive industry, arts and e-learning.

You can view the full proceedings and some photos of the event.

We are back! See you @ HCI-IS 2019

After a short brake, the Slovenian HCI community is back with the Human-Computer Interaction in Information Society. As always, in October in Ljubljana, Slovenia.

This is the first edition since ACM SIGCHI Chapter Bled Slovenia was established. All you need to know is listed in the CFP available here.

We are waiting for your contribution – full research papers, work in progress, demonstrations – until the end of summer (30.8.2019). The conference takes place on Wednesday, the 9th of October.

See you soon!

Interactive Video Management by means of an Exercise Bike

Jan Štrekelj, Branko Kavšek
University of Primorska Faculty of Mathematics, Natural Sciences and Information Technologies Glagoljaška 8, 6000 Koper, Slovenia

Abstract: This paper describes the concept of virtual reality and the use of this technology in practice. The main part of the work is about reviewing the various stages of the development of a prototype system for interactive video management by means of an exercise bike. Systems, that are currently available on the market, are, due to their ease of use, closed units, for which upgrades are not possible or come at a great expense. The main advantage of the presented prototype, besides affordability, is a simple option to upgrade the system by adding sensors and/or modules; this allows us to extend the system in every stage of development. A low-cost computer (Raspberry Pi) is used as a processing unit, for calculating the speed of the wheel and sending this information to the control unit. The control unit processes the received data and sets the playback speed of the video clip accordingly. There is great potential for improvement on the developed prototype. Thus, ideas for further development are presented in the concluding section.

I was here: a system for creating augmented reality digital graffiti in public place

Erik Šimer, Matjaž Kljun, Klen Čopil Pucihar
University of Primorska, FAMNIT, Glagoljaška 8. Koper, Slovenia

Abstract: Since ancient times travelers and tourists try to leave their marks in places they visit. However, carving or writing on historic landmarks can cause irreversible damage on such sites. One possible solution are digital graffiti. These can for example be created through projection mapping where beams of light wrap the object with the digital graffiti created by users so everyone at the site can see them. However this may disturb other visitors being there at the same time. In this paper we explore an alternative solution for creating digital graffiti by utilizing Mobile Augmented Reality (MAR) technology. We developed a mobile application which allows users to: (i) select an object or a building, (ii) map a 3D mesh onto it in order to prepare its 2D plane , and (iii) draw a graffiti on this plane. After completing the drawing the application wraps the object or the building with a modified 2D texture creating an illusion of digital graffiti. In order to (i) evaluate the social acceptance of placing digital graffiti onto historic landmarks and to (ii) evaluate if the use of our prototype is socially acceptable in public spaces, we carried out a small reflective user study. We created a couple of simple graffiti on different historic buildings and posted them on social networking site Facebook. Despite amateur appearance, posted photos received attention and generated some positive responses and questions.

Towards affordable Mobile Crowd Sensing device

Gal Pavlin
University of Ljubljana, Faculty of Electrical Engineering Trzaska 25 1000 Ljubljana

Jožef Stefan Institute, Jamova cesta 39, 1000 Ljubljana, Slovenia

Abstract: In this paper, we describe first prototype of mobile crowd sensing device. The device serves as a source for signals in the potential crowd sensing studies. Presented device has no intention to compete with the existing mobile devices, such as mobile phones, but to complement them where they lack of the features like affordability, simple use and new opportunities in different segments of our lives. Our main goal was to develop a device, which can cover all aspects of mobile crowd sensing and at the same time to keep the device cost at very affordable level. The described device is capable of integration into most widely available sunglasses. The complete device consisting of two separate “lenses” forms distributed ecosystem serving as source for sound, light, acceleration and temperature signals while at the same time providing actuator function with integrated LED matrix display.
