Användarcentrerad gränssnittsdesign för 3D-skanningsbaserad sadelutprovningsprocess

Abstract

Saddle fitting relies on experience-based assessments and practical knowledge. Emerging technologies such as 3D scanning create opportunities to complement these assessments with more detailed information about the horse’s back and the fit of the saddle. Measurement data can support and further inform practical assessments. The aim of this bachelor’s thesis was to investigate how a user-centered interface could be designed to support the management and visualization of 3D scans and measurement data within the saddle-fitting process. The project was conducted with SaddleScanner and included interviews with saddle fitters and representatives from riding schools. Based on the identified needs, a mobile interface was developed in Figma and evaluated and refined through two rounds of formative user testing. The user tests showed that the participants could understand and use several of the interface’s core functions. However, the matching process, which constituted the interface’s main function, was perceived as difficult to initiate and complete because the structure of the interface did not fully align with the users’ mental models. Since the workflow was new, the participants lacked an established mental model to rely on, making it difficult to understand which steps to take and why they had to be performed in the given order. The project resulted in an interface proposal in which functions and information were structured according to the users’ mental models. Clear guidance, continuous feedback, and a logical starting point were identified as central factors in making the interface intuitive and efficient to use.
