In this context, we investigate the role of se- mantic and spatial cues for delivering event notifications within the control environment, and present empirical evidence from a controlled laboratory study, simulating a marine industrial envi- ronment. We find that spatial and semantic cues can both offer significant benefits to operator awareness and their combination can significantly improve the findability and response time to par- ticular information in the extended information space surrounding the user.}, keywords = {Attention Management, Control Rooms, Cyber-physical systems, Industry 4.0, Internet of Things, Notifications, Virtual Reality}, doi = {10.1145/3489410.3489429}, author = {Konstantinos Tsigkounis and Andreas Komninos and Nikolaos Politis and John Garofalakis} } @conference {105, title = {Interacting with large maps using HMDs in VR settings}, booktitle = {19th International Conference on Human-Computer Interaction with Mobile Devices and Services (MobileHCI {\textquoteright}17)}, year = {2017}, month = {09/2017}, publisher = {ACM}, organization = {ACM}, address = {Vienna, Austria}, abstract = {Location based services are a common application scenario in mobile and ubiquitous computing use. A typical issue with cartographic applications in this domain is the limited size of the displayed map, which makes interaction and visualization a difficult problem to solve. With the increasing popularity of head mounted displays for VR and AR systems, an opportunity is presented for map-based applications to overcome the limitation of the small display size, as the user{\textquoteright}s information visualization space can extend to his entire surroundings. In this paper we present a preliminary investigation into how interaction with such very large display maps can take place, using a virtual reality headset as the sole input and interaction method.}, keywords = {Augmented Reality, Digital Maps, interaction, Map-based applications, Virtual Reality}, doi = {10.1145/3098279.3122148}, author = {Ioannis Giannopoulos and Andreas Komninos and John Garofalakis} } @conference {107, title = {Natural interaction with large map interfaces in VR}, booktitle = {21st ACM Panhellenic Conference on Informatics}, year = {2017}, month = {09/2017}, publisher = {ACM}, organization = {ACM}, address = {Larisa, Greece}, abstract = {Location based services are a common application scenario in mobile and ubiquitous computing.
