Abstract: Embodiments of the claimed subject matter relate to devices, systems and methods using those devices used in improving the skill of one or more users, and more particularly, devices that can be used to view, record and playback activities which can be reviewed later and used for training feedback. One example includes positioning one or more audio or visual or audio visual recording devices having an unobstructed view of a performance area, recording video and/or audio of the one or more participants within the performance area over a period of time, processing the video and/or audio recordings and storing said recordings as a digital file format to one or more digital storage devices connected to a computer network, and allowing the stored digital files to be played and viewed over the computer network.
