It is expected that the user’s sense of symbiosis will increase with improvements in the accuracy and attentiveness of the CEEDs engine and naturalness of expected response of the display (output) to users’ explicit responses (inputs). This relies on the system understanding what users consider appropriate and expected. This area is generally well understood in HCI. In contrast, user responses are called ‘implicit’ when they refer to covert, uncontrolled responses that are ‘unconscious’. , blink rate, eyetracking, reflexive postural and physical responses, vocal emotion).

Blink rate, eyetracking, reflexive postural and physical responses, vocal emotion). Unlike explicit user responses, it is not yet clear how users might expect the display to ‘intuitively’ respond to their own implicit responses to the content display and indeed how this impacts on subsequent explicit and implicit action loops. How will we make sense of being faced with our own responses that previously lay beneath our conscious awareness? 4 Key Variables in Human-Computer Interactions In this initial taxonomy of human-computer (symbiotic) interactions, user responses that are implicit or explicit can be relevant, or not, to any particular CEEDs session.
