Abstract:

In certain disciplines, it is necessary to access information in large digital images, and because of their size and resolution characteristics, they are difficult to store, transfer and navigate in low capacity devices. Additionally, nowadays the requirements of portability and ubiquity of applications are present in different professional activities. Consequently, development of applications for mobile devices has a great potential for improving different activities with the adequate support from emerging technology. However, it is important to note, that the intrinsic characteristics of these high-resolution images require specific strategies to achieve an efficient way to visualize them in limited capacity devices. On the other hand, most of the interaction interfaces are not easy to use because of their configuration or the need to use complex gestures, which requires both hands, one to hold the devise and the other to interact with the content.. This paper presents the design and evaluation of the user experience in the use of mobile devices with three models of interaction, in which it is possible to navigate in high-resolution JPEG2000 images in a flexible and scalable way, focusing in particular areas of interest. The models were designed for limited scenarios in which the user has only one hand to use the device, and they were evaluated by means of standards of usability and accessibility. This development takes advantage of new technologies and proposes an interaction model effective, efficient and accessible to navigate images, exploiting the advantages of touch screens, saving time and facilitating activities that require using images in fieldwork assisted by
