4. Animation and sound: As discussed above, the appearance of the agent will have an impact on the learner's affective state, both during and after the interaction. A well-known and respected character, such as one modeled after the First Lady (if possible), will increase the chances of establishing familiarity and credibility from the outset. Use of appealing animations and joint activity, such as watering the garden simultaneously, will bolster feelings of co-presence and teamwork. The character's voice, which will be delivered along with subtitles for English as a second language learners, will be chosen based on the preferences of users from the target audience in early testing of the system.
