Digital electronics augmented remote laboratory: DEARLab

A new concept of a remote lab that allows the implementation and measurement of all types of digital electronics design, known asthe Digital Electronics Augmented Remote Laboratory (DEARLab), is presented in this paper. This remote lab allows remotewiring of the elements of real circuits, so that DEARLab deals neither with models nor simulations. The prototype remotelyimplemented by the user is a real circuit with all the real signs (voltage and current levels) that circulates through real circuitelements inserted into a real breadboard located in a real lab, so that the implemented prototype presents the common drawbacksof real circuits (delays, faulty elements, etc.). DEARLab allows the user to feel as if they are being present at the physical lab,whose capacities are enhanced by virtual elements that interact with their real counterparts by means of augmented reality.DEARLab has been subjected to validation as an educational tool. The first results show high acceptance by the students.
