Neurodiversity, increasingly recognized in society, encompasses a range of neurological differences, including autism, ADHD, and dyslexia. In software engineering, addressing neurodiversity is crucial to designing accessible and inclusive products that accommodate diverse user needs. Despite growing interest, a clear understanding of how to create neurodivergent-inclusive software remains underdeveloped. To help bridge this gap, we developed a conceptual model that identifies key neurodivergent concepts and relationships to guide software requirements elicitation. This model was evaluated through a survey involving 100 participants, including 37 neurodivergent individuals. These initial evaluation results are encouraging and indicate the model has the potential to advance the creation of software accessible to neurodivergent users. Moreover, the survey also revealed several necessary improvements towards successful requirements elicitation support. To this end, we envision addressing the completeness of the collected information and identifying contradictions between accommodation strategies. Based on the complete conceptual model, we will create a requirements elicitation method on top of traditional elicitation methods, such as focus groups or workshops. Additionally, we will build an elicitation tool on top of large language models, allowing requirements engineers to effectively elicit neurodivergent-inclusive requirements.
