Objective: Nonverbal and verbal communication elements enhance and reinforce the consent form in the informed consent process and need to be transferred appropriately to multimedia formats using interaction design when re-designing the process.
Methods: Observational, question asking behavior, and content analyses were used to analyze nonverbal and verbal elements of an informed consent process.
Results: A variety of gestures, interruptions, and communication styles were observed.
Conclusion: In converting a verbal conversation about a textual document to multimedia formats, all aspects of the original process including verbal and nonverbal variation should be one part of an interaction community-centered design approach.
Keywords: Informed consent; gestures; multimedia; user-computer interface.
