Depending on a person's disability, their accessibility needs can vary greatly. The type of disability, its severity, and the technology people use can affect how users interact with the product. To account for these factors in your research, aim to recruit:

• People with different disabilities: Visual, physical, cognitive, auditory, and speech-related.
• People with varying degrees of impairment: For example, within visual impairments, look for participants who are color vision deficient, have low vision, or are blind.
• Users of different kinds and brands of assistive technology: For example, when recruiting screen reader users, look for people who use different brands like JAWs, NVDA, TalkBack, or VoiceOver.^[1]
