Create a remote and fully manageable multimedia system, able to propose the interviewee a multimedia questionnaire. Barcodes, recorded voice notes, photographs and video must also be captured. The system must be equipped with GPRS connectivity for remote configuration and data transmission to a cloud system.
The Dialogatore is a multimedia terminal based on a low power Marwell PXA320 processor running a Linux operating system for the management of a touch screen display and a graphics interface. When the main processor is in stand-by mode, an auxiliary processor deals with the other functionality of the system. The system is equipped with numerous devices that expand the functionality: secondary OLED display, programmable function keys, high efficiency bar-code reader, video camera for photos and video acquisition, GPRS modules for data transmission and remote management of the device. The loading of the questionnaires is done through a cloud system that also allows to define the specifications for compiling the questionnaires (scheduler). System maintenance, inlcluding software and firmware updates, is fully automatic and remotely managed.
