Human-computer interaction extended resource model based on distributed cognition

Traditional resource model based on distributed cognition mainly includes two major parts, which are resource information structure and resource information interaction. To improve this models capability in resource description and practical application, the description of resource in this model is to be classified by two categories, which are the forward resource information structure and backward resource information structure from the view with the extending of resource information structure in this model, and the relationship between the two structures is emphasized to make the resource model be more universal. Moreover, the resource information interaction is changed from single cycle to double cycles from the view with the extending of resource information interaction strategy in this model, and the fusion effect of the information resource during the interaction process also places emphasis on making the resource model be more flexible. The new extended resource model can reduce the overload of users cognition and improve the efficiency of human-computer interaction (HCI).
