Adaptable Interface Framework for Intuitively Learnable Product Interfaces for People with Diverse Capabilities

WithGudur Raghavendra Reddy, Alethea Blackler, Vesna Popovic

The intuitive use of an interface involves the non-conscious use of prior knowledge, and designing for intuitive use requires that an interface is designed to match the prior knowledge and competence of a user group. This process is effective when the target user group's prior experience is homogenous. However, it is challenging to implement this approach when designing for older people, mostly because of their diversity in terms of technology familiarity (TF) and cognitive abilities. One of the important reasons for older people finding contemporary interfaces difficult to use is their low prior experience or TF. TF and competence with technologies related to the product are essential for the intuitive use of its interface. Interfaces that adapt while in use are generally termed adaptive interfaces. There are various mechanisms of adaptation: automatic system-based adaptation, adaptation by system–user cooperation, adaptation by an expert intermediary, and adaptation by the users themselves.
