“…Fisher summarizes current research on photosensitive epilepsy across a range of topics including characteristics of seizure-inducing light sequences based on medical trials, seizure prevention methods, and the history of light-induced seizures triggered by modern technology [25]. Several works over the past ten years have examined methods for reliably detecting seizure-inducing light sequences in films and videos [4,7], GIFs [65], and interactive data visualizations [64]. South et al additionally conducted qualitative interviews to understand people with photosensitivity's perspectives on safety and accessibility within social media sites such as Twitter (X) and Reddit.…”

“…Testing content for flashing lights is common practice in film and television [7,17,50] but is less commonly used with interactive media due to the unpredictability of interactive content [65]. Methodically testing all possible combinations of states that could produce a flickering effect is feasible with simple interactive webpages or data visualizations [64], but would require a prohibitive amount of computing power for more complex VR applications. Crowdsourcing information about flashing lights in individual VR games, applications, or worlds could be an alternative approach for identifying flashing lights in VR worlds that are too complex to automatically test for seizure-inducing sequences given the current efficiency of testing algorithms.…”

Virtual reality (VR) systems have grown in popularity as an immersive modality for daily activities such as gaming, socializing, and working. However, this technology is not always accessible for people with photosensitive epilepsy (PSE) who may experience seizures or other adverse symptoms when exposed to certain light stimuli (e.g., flashes or strobes). How can VR be made more inclusive and safer for people with PSE? In this paper, we report on a series of semi-structured interviews about current perceptions of accessibility in VR among people with PSE. We identify 12 barriers to accessibility that fall into four categories: physical VR equipment, VR interfaces and content, specific VR applications, and individual differences in sensitivity. Our findings allow researchers and practitioners to better understand the meaning of photosensitive accessibility in the context of VR, and provide a step towards enabling people with PSE to enjoy the benefits offered by immersive technology.

“…Recent research on accessibility for people with photosensitive epilepsy has focused on accurate and efcient detection of seizureinducing content in videos [1,3], GIFs [16], and interactive data visualizations [15]. Conversely, this work focuses on the question of how to communicate information about photosensitive risk to the viewer after a risk detection system has already identifed the potential hazard.…”

Films often include sequences of flashing lights for visual effect that may inadvertently trigger seizures when viewed by individuals with photosensitive epilepsy (PSE). Warnings about photosensitive risk in films can help people with PSE make informed decisions about their personal safety, but little is known about how to design such warnings and what information to include. To better understand the design space for photosensitive risk warnings, we conducted a qualitative analysis of 265 crowdsourced warnings about flashing lights in films. We find that the crowdsourced warnings were tightly coupled to the scenic and temporal contexts of the films being described, unlike current practices for labeling media with potentially seizure-inducing sequences using general warnings that are not specific to the media at hand. As technological capabilities for detecting seizure-inducing sequences continue to improve, understanding how to efectively communicate this information toindividuals with photosensitive epilepsy is critical for ensuring accessibility.

“…However, physical and cognitive abilities can also influence how people work with data visualizations [49]. For example, past studies have investigated how particular designs may induce seizures in people with epilepsy [23,60]. Of particular relevance to this work, Wu et al [68] conducted a mixed methods experiment to understand how people with IDD interpret common data visualizations in the context of financial self-advocacy.…”

Figure 1: People with Intellectual and Developmental Disabilities (IDD) use personal data to make sense of everyday life. Participants with IDD most frequently used data to track activities of daily living (e.g., nutrition log, checklist, and everyday documentation); however, this data was often invisible to people despite being used in a variety of common scenarios, such as to advocate and shape treatment in healthcare applications. We synthesize limitations in existing approaches to working with data and opportunities for using visualization to enhance data accessibility for people with IDD. For example, participants and their caregivers identified a range of scenarios where data had significant potential to help people with cognitive and communicative impairments better participate in social and self-advocacy situations.
