Abstract: A system and method for prioritized interface design are disclosed. In one embodiment of a system incorporating teachings of the present disclosure, a wireless-enabled device may include a display, a user input mechanism, and a housing component that at least partially defines an internal cavity. The device may have several engines including a display engine that can initiate presentation of a menu that has several selectable items displayed in respective menu positions. The device may also include a metric engine that tracks some selection metric for the selectable items and a priority engine that determines a prioritization level for the selectable items. In some embodiments, the prioritization level may be related to a selection metric. The device may also have a mapping engine that modifies assigned menu positions for the selectable items in response to changes in the prioritization level of the items.

Abstract: A method is provided for designing an interface system. The method includes receiving a call from a customer at a call center, and logging a reason the customer is calling the call center. Subsequently, reasons from multiple customers are collected and categorized into task categories to be performed by the interface system. Menu options can then be designed based upon the task categories. The menu options include some of the language the customers used to express the reason for calling the call center. Performance of the interface system is evaluated by using cumulative response time (CRT), which is a total time a user interfaces with the system, and routing accuracy. The routing accuracy accounts for whether the user successfully navigated the interface system to a correct destination, whether the user navigated to an incorrect destination, and whether the user did not navigate to any destination.

Abstract: A method of designing an interface system that allows users to map the representation of their task directly to the interface. There are three major phases to the Customer-Centric Approach to Interface Design (C-CAID). End-users' tasks are categorized to determine the frequency of reasons or tasks of why users interact with a particular system. These reasons and their relative frequencies are used to design interface options that emphasize the user's task categories. Finally, the customer-centric interface designs are evaluated and compared with existing system interfaces using usability tests with actual users performing the tasks. The results from usability tests are used to pinpoint the task-option combinations that do not work well and which should be revised. Benefits of this customer-centric design are improved systems performance and increased user satisfaction.
