Limitations

Despite providing promising results, this study has several limitations. Firstly, as in most accessibility research, people with intellectual disabilities were underrepresented in this study. Unlike with other groups of disabilities, this group was younger in age and their caregivers responded on their behalf. We suspect that caregivers are mostly women, who may have special needs that we have not sufficiently captured here, and may require a separate study and analysis in the future.

One more limitation of this study was that we have not elaborated on the users’ intentions to use the digital assistive technologies, as the survey did not include asking participants to justify their chosen answers. Hence, in future research, it is important to find out more about how familiar persons with disabilities are with digital assistive technologies, and what other possible factors could impact their choice of using this particular assistive technology or not.

Finally, it should also be further emphasised that the sample is most probably biased by the self-selection of participants. Thus, poorly connected people or people with limited access to the internet might not have received the invitation. The rather low average age of respondents indicates that the survey may have had some problems in reaching older persons with disabilities.
