Investigators will try to develop algorithms that will recognize multiple objects and persons in real-time (enhanced scene interpretation for multi-object identification). And based on that, human-centered simulation trials and experiments for feasibility and efficacy of the platform's tactile and auditory 'communication' outputs will be conducted. Finally auditory and tactile 'prompts' (system output) based on the end user's immediate needs based on initial testing results, will be integrated into the platform.
