Only a few time ago, the representation of indoor environments got the attention of the researches. Earlier studies on indoor visualization have focused primarily either on static, printed emergency maps or maps on early prototypes of mobile. Besides that, great part of the research has been directed to positioning methods rather than the representation of such environments.
On the other hand, users are claiming for location based services for indoor environments. Big companies such as Apple, Nokia, Microsoft and Motorola have been investing in this market. Moreover, it is also necessary to consider that these environments became bigger and more complex. In some cases, the navigation task can be a challenge. Indoor environments have some characteristics that make them different from outdoors environments: orientation and navigation are different and landmarks can change frequently.
Therefore, we are investigating some important issues about the indoors representations, such as which is the best map design, which elements of the indoor environments can be considered as reference points, or what is the best device for display. In order to obtain answers for these questions we have proposed a research that is being conducted at Federal University of Parana (Brazil). We developed a database with different buildings of the University, and all interior spaces were stored and categorized by its use (classroom, staff rooms, administrative spaces, commercial areas and bathrooms). Some of these buildings have several floors and a high level of complexity
The first aspect addressed by the research is about the map designed for an indoor environment. We propose the use of two different maps: a schematic maps and the traditional floor plans. Schematic maps (SM) are mainly used for transport networks, and there has been significant research on methods for obtaining a schematic representation from a topological structure. Considering the lack of methodologies in indoor mapping research and the possibilities for SM use in supporting way-finding tasks, we proposed an indoor SM, and to verify user preferences regarding indoor maps, we developed a survey using an indoor map, similar to a floor plan (FP) and the designed SM. The survey was conducted using a 10” tablet and the users where asked to accomplish different tasks using the designed maps. So far were tested 30 users and they were divided into two groups, each one has used one kind of map. Tasks were related to wayfinding and object recognizing. A questionnaire was also applied after the test. From the answers for the questionnaire it was possible to conclude that the users who used the SM accomplished the tasks easily, when comparing with the users who used the FP. Also, the first ones affirmed that the SM had facilitated the orientation task. This survey also had pointed some possible reference points users can use in indoor environments: stairs, bathrooms and elevators.
In a second experiment, the users were divided into two groups and should navigate between two points. One group had only a digital map to perform the task and the other one could obtain their position from QR-Codes placed in some reference points mentioned in the previous experiment. In this experiment, we conclude that the use of the QR-Code is an alternative to positioning in the indoor environment. Also, the results confirm the same reference points were used to orienting and navigation.
Further studies need to be done to confirm the mentioned reference points as real landmarks in the indoor environments, as well as verify the best design for represent multiple floors. Also, a new route algorithm is being developed to provide navigation between different points.
