Prioritizing UI Items for Bidirectional Design System Development: A Suggested Set of Criteria and its Implementation
Yulia Goldenberg, Noam Tractinsky · CHI Conference on Human Factors in Computing Systems Extended Abstracts · 2022
Design systems provide detailed guidelines on UI items’ appearance and behavior and serve as a primary reference for interface development. For bidirectional languages (e.g., Arabic and Hebrew), it is essential to highlight an additional parameter – the direction of the UI item. However, investigating the correct direction of all items could involve costly research. Hence, it is important to set priorities for such research. While prioritizing usability issues has long been attended by the HCI community, the specific problem of this research is new and has never been addressed. To deal with this challenge, we conducted five focus groups with HCI professionals and identified a set of prioritization criteria. We then used those criteria to prioritize the UI items for future empirical evaluation of their preferred directionality. In addition to these findings, we provide some insights from our experience of using focus groups for the prioritization task.
