Abstract [en]

This paper purposes an application based on video supervision systems in the zoo for human animal computer interaction. Bear-Watcher system covers the entire process from collecting animal's visual data, analyzing their movement and behavior, and presenting them to user interface for tourism and animal welfare. With the interaction between the users and animal movement information, the system gives the tourist more digital, more available, more involved experience. In the meanwhile, zoo keepers get reliable, accurate, cost-effective way to take care of animals.

Abstract [en]

In this paper we will describe a positioning system based on synchronized IR light. Each node will be assigned a timeslot where they will send out an IR light. There is an IR camera that is also synchronized to the timeslots that will detect the position of each node and the ID that corresponds to the timeslot. To synchronize the clock of all nodes an IR flashlight is sent out that is detected by a photodiode on the nodes. The demo will show live video stream from a network camera where the ID and position of each node in view will be overlaid in real-time in the video.

Abstract [en]

In Norway, Sweden and Finland approximately 9.000 reindeer are killed every year in traffic accidents (road and railway). In field experiments two different electronically sensor system were used. The purpose is to warn car drivers and railway engineers that reindeer are close to, or on the traffic system, and reduce the numbers of accident. The information system developed by Telespor is based on GPS/GSM radio collars. These collars use SMS to inform that the reindeer are close to the traffic system. In addition to the warning, the reindeer owners get information about the reindeer land use throughout the whole year. The collars are expensive (approx. 250 euros/unit) and need battery change every year. At Umeå University a system based on wireless sensor nodes attached to the reindeer collars is developed. This node will send out a periodic warning radio beacon. On road sticks a warning device will be attached containing a radio receiver and LED flashlights that will warn if a radio beacon is received. To further increase the warning distance it is possible to use communication between the roadside warning devices and let several devices flash their LED lights when a reindeer is detected. The radio collar (approx. 15 euros/unit) will have a theoretical battery life of more than 10 years. The radio range is around 500 meters between the radio collar and the roadside warning device, which is more than sufficient.

Abstract [en]

In this paper the authors present an approach to provide efficient low-complexity encoding for the block-based video coding scheme. The authors present a method based on removing the most time-consuming task, that is motion estimation, from the encoder. Instead the decoder will perform motion prediction based on the available decoded frame and send the predicted motion vectors to the encoder. The results presented are based on a modified H.264 implementation. The results show that this approach can provide rather good coding efficiency even for relatively high network delays.

Abstract [en]

This paper proposes a consumer-oriented design of Interaction System applied in a digital zoo. In order to introduce a new experience of visiting zoos, a series of interaction interfaces and applications is designed based on the web surfing. The applications can be located anywhere has Internet connection, used by visitors both in and out of the zoo. In the meantime, zoo staffs can use the system implement to manage the zoo more efficiently on both computer and smart phone. The digital zoo, as the showcase of the interaction system, employed the technology that combine radio frequency identification (RFID), wireless camera sensor network and computer vision system for collecting and processing information in a reality zoo. The Interaction System for digital zoo enhances effective interaction behavior between human-animals, human-human, and management over animals. The design is based on the Digital Djurpark Porject with current deployment a multimedia sensor network for human animal machine interaction. We have evaluated the effect of interaction model in field experiments.

Abstract [en]

In this paper a conceptual model for a social media game will be illustrated. The idea is to find a way to integrate our physical and digital world in a way that will involve the environment around us containing both artifacts and people and become a natural part of our daily lives. We want to show that by integrate ubiquitous information and social media in a game idea, it is possible to create a concept for a social media game application that could be used at a tourist attraction, e.g. a zoo. The value that is received from this application is both educative for the visitors and marketing for the tourist attraction. The conceptual model of the social media game builds upon the foundations of internet of things for the future version of a tourist attraction, such as the Digital Zoo.
