Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that, in recent years, has seen increased growth in the number of
individuals to be diagnosed. The result of this development has caught the interest of the HCI community, from which a foundation for
future research has been established. To this, most research efforts are well-regarded to design and develop inclusive solutions, which
contributes to spreading awareness about ASD to change the public perception of the disorder. However, within these ASD-related
studies, it is observed that the capability of HCI researchers and practitioners to facilitate collaborative activities with ASD participants
is often questionable regarding developing solutions that the user segment can relate to. To resolve this uncertainty, this article
presents a co-design tool in the form of design method cards called Autism Spectrum Experience Cards(ASEC), which can be used
for, with and to ASD users that can be used in the early design phases of a design solution. Throughout the tool’s development,
an interview and a series of evaluation sessions were held with relevant stakeholders to ensure the understanding of ASEC and be
representative of ASD users. By the end of the article, the findings showed that ASD representatives were able to relate to the card’s
contents and prompted their ability to self-reflect in association with their answers. Finally, the article concludes in regards to its
contribution, in that there might be an opportunity to develop other design method cards with other user segments in mind.
