The fundamentals of Human computer Interaction

Human computer interaction can be described as a succession of elementary micro events (duration :milliseconds):

Clicking with the mouseType on keyboard

Detecting icons on the screen...

CMNKL model provide a set of operators describing HCI events.This is the basis of some studies aiming to assess human computer interaction or to improve user interfaces design options.

1.USE CMNK EPIC OPERATORS AS HCI PARAMETERS

HCI characterization is possible reffering to CMNK and EPIC models.The operators of those models

can be seen as descriptors aka parameters of basic events of User 's task performance.

On-field User Experience Profile Assessment

Questionnaires are traditional tools for HCI assessment. There are plenty of questionnaires or interviews to lead in the context of HCI

on-field evaluation.E ach question focuses on a particular HCI micro event, an CMNK or EPIC operator.

Questionnaire format for CMNK EPIC operators implementation

One site assessment implies easy -to -manage data support. The technician leading the assessment select a set of questions. The challenge is to perform HCI exploration via a short interview and without bias linked with this kind of protocol.The User's responses are registered in a paper file before scanned or recorded as numeric file.

GET A REPRESENTATION OF USER

EXPERIENCE VIA CMNKL EPIC OPERATORS The importance of each operator is issued in a histogram .ThIs simple graphic allows basic stats of HCI.

The USER's MODAL Profile:HCI style is in this case study marked by preeminence of keystroking and mouse pointing MODALITIES with a high degree of interruptions (spams? slowness of computer processor? low speed of the Internet connection?)

Occurrence calculation is performed by computerization of User's answers to questionnaire

Semi quantitative representation of human computer interaction events

CMNK EPIC CYBNERNETICS INDEX Given the occurrences of CMNK EPIC operators , one can build a scale for a

semi quantitative evaluation of HCI elementary tasks.

The value of each operator is a rank of a cybernetics scale.

This value is a descriptor or a indicator of the User’s state for the considered HCI mode.

Implemented operators are called Cybernetics Index.

By using CMNK EPIC operators We can create MODAL CYBERNETICS INDEX

for HCI analysis , based on User’s Experience.

By doing so , we now have a Modal representation of HCI.But this form is not directly usable for clinical purpose.
