This document presents a case study evaluating the acceptability of an online emotional therapy system called TEO for applying homework assignments between therapy sessions for a patient diagnosed with adjustment disorder. The case study involved a 35-year old woman who received a cognitive-behavioral therapy program utilizing virtual reality. Questionnaires assessed her preferences and acceptability of using the TEO system versus traditional homework assignments. Preliminary results found the patient found the TEO system useful and easy to use for completing homework assignments at home between therapy sessions.
