Telepresence learning environments for opera singing, a case study

The present study analyzes the data obtained in the execution of the Opera eLearning project, a multidisciplinary effort to develop a solution for Opera singing distance lessons at the graduate level, using high bandwidth to deliver quality audio and video experience that has been evaluated by singing teachers, chorus and orchestra directors, singers and other professional musicians. The research work includes the phases of design, execution and evaluation of pilot tests, followed by further development and execution of several experimental exercises with the system, all of them carried out between July 2008 and April 2009. This is an empirical research, an exploratory case study that has provided enough data to arrive to a sustainable model for a telepresence learning environment. Different usability methods have been implemented in order to assure users of the quality of the product. The main objective is to prove whether the system or artifact proposed can be used to deliver a complete remote singing class at a higher education level; for that purpose, we have defined several research categories that describe the usability of the system in multiple dimensions. We have used “design as research” approaches to promote innovation in the technological area. The theoretical framework is based on a wide variety of fields; from acoustics, physics, music, professional singing to telecommunications and multimedia technology. However, the common thread and central issue under analysis is distance education, through the construction of a remote learning system. We have also included the corresponding justification of the scientific methodology employed
