This report outlines the design of an interactive reading assistance system aimed at enhancing reading efficiency and experience for individuals with dyslexia.
The design process is divided into four phases: Discover, Define, Develop, and Deliver.
The Discover phase inc ...
Deceptive design patterns (also known as 'dark patterns') are design elements that trick users into unintended behaviors that harm them and benefit the party implementing the design. Prior work has taxonomized, investigated, and speculated the presence of dark patterns across env ...

Integrating cognitive user data in journey maps

Explorations towards designer affinity

User-centric design practice rely on journey maps and personas as a way to communicate user needs to the design team (Lanius et al., 2021). However, journey maps in practice have been found to lack a dimension that could inform designers about intrinsic cognitive needs of the us ...

This thesis explores design interventions for individuals with Developmental Topographical Disorientation (DTD) and others with weak navigational skills. “DTD refers to the lifelong inability to orient in extremely familiar surroundings despite the absence of any acquired brain damage or neurological disorder” (Iaria & Burles, 2016) This research focused on addressing the gap between allocentric navigation (map-based, provided by technology) and egocentric navigation (personal perspective), which many individuals with DTD struggle to translate effectively in their daily life. 


The research goal was to explore how to better support people with DTD, as well as others with below average navigational skills, in bridging the gap between these two navigational perspectives. Interviews with students and recent graduates who self-identified as having poor navigational skills revealed low spatial anxiety, likely due to their reliance on GPS. Based on these interviews and navigation technology research, wayfinding guidelines were developed, emphasizing clear visual landmarks that simplify the cognitive translation between map-based and personal navigation.


A design concept was created which presents the directions to take in a landmark based map, with a song as a mnemonic aid to learn the navigation instruction. Focusing on how individuals use both allocentric and egocentric perspectives to navigate an evaluation with participants who self identify as not having good navigation skills, navigated a virtual environment using the concept. Results showed that while a multisensory approach can be useful, clear and simple visual cues, such as the selection of one specific landmark per decision point, are more effective in aiding navigation.


In conclusion, the study shows design guidelines to simplify the transition between allocentric and egocentric navigation, and to motivate the user to memorize the route rather than relying solely on technology or multisensory tools. It also highlights the need for greater awareness of DTD and offers insights into designing accessible, user-centered navigation tools.

Cooking is an essential part of most people’s day-to-day lives. It is a dynamic activity that involves multitasking, timing of tasks, and flexibility. However, the available instruction methods for cooks who wish to follow recipes are quite rigid and linear. This project aims to ...
