Abstract
E-catalog is a marketing media that aims to make it easier for consumers to get information about a product, including the type of product, the shape of the product even the price of the product. One of the official motor dealer in Indonesia has a Spare Parts e-catalog. Unfortunately, this application still has problems with the user interface, so it makes the user hard to get the information they need. This also strengthened by the low usability test results using the USE Questionnaire. The observation also showed that the image of the spare part is unclear so that makes it difficult for users to get the information and imagine the original shape of the spare part. The low usability results also indicate that this application is still difficult to use, difficult to learn and unsatisfactory for consumers. Based on those problems, a redesign of the user interface is required to assist users in obtaining the required spare part information. Appropriate technology for visualizing spare part images in more detail is Augmented Reality (AR). The re-designed user interface has built using The Goal-Directed Design (GDD) method for accommodate on achieving the goals of the user and the dealer. The prototype then evaluated by USE Questionnaire, and the usability value increased to 84%. This result indicate that the re-designed user interface of the application can facilitate the user in finding the information needed with easier way and satisfying.
