Which device is commonly used for communication in telesupervision?

The use of a webcam is particularly relevant in the context of telesupervision as it allows for real-time visual communication between supervisors and supervisees. This technology facilitates face-to-face interaction, which is essential when providing feedback, conducting assessments, or discussing therapeutic techniques. A webcam enables the parties involved to see non-verbal cues and body language, enhancing the quality of communication and the effectiveness of supervision.

In contrast, while a digital recorder captures audio information, it does not provide the visual component necessary for effective supervision. A smartphone, although it can facilitate communication, may not offer the same level of stability and clarity necessary for professional supervision as a fixed webcam setup might. Finally, a fax machine would not be suitable in this context as it is primarily used for transmitting printed documents, lacking the interactive capabilities that a webcam provides.
