RESUMO

Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3D graphics) on the handheld devices display. New Handheld AR applications use a mobile phone camera, markers and wireless sensors (inserted into the environment) as elements for dynamic data entry into the AR system. These applications show interesting characteristics for: sensing, visualization and interaction in ambient intelligence (AmI) and ubiquitous environments. But, the lack of documentation and complexity development process produce the need for methodologies and tools for a fast and simple development model. For these reason, this work presents a Methodology for Design and development Handheld AR applications, which present an especial support for mobile phones and wireless sensor networks, making a description and clear roadmap of the requirements and characteristics in the Handheld AR development process model. Our methodology proposed presents a general scenario of application, a software architecture and application development guidelines. Moreover, we present implementation details over: acquisition data process, semantic modeling data, development of user profiles and visualization of the information using AR techniques, showing these information as virtual objects (virtual images, vibration effects and sound effects). These virtual objects use the handheld device as interaction interface between the user and real world. Finally, we present a case study that develops a Handheld AR application (prototype) to monitoring the temperature in the PAD (Pervasive and Distributed Computing Group) servers room. In this case study, we describe the materials, the scenario, the services offered, the development process and prototype evaluations.
