The Mobile Phone-based Video Streaming (MPVS) system has continually been improved following interaction and evaluation with the relevant stakeholders, primarily lay users, trial managers and developers. Following on from these evaluations, a user interaction framework was extended to provide guidance relating to the selection of information elicitation techniques during all stages of technology development. This framework may be employed when planning assistive technology development in order to achieve a technology-driven, yet user-led, methodology that leads to informed decision making based on real needs, requirements and feedback.
