The labor market inclusion of people with intellectual dis- abilities is one of the main concerns of current societies. Non-profit associations make every-day efforts to improve the living conditions of these citizens. This contribu-tion presents a heuristic evaluation of an educational mobile game helping social workers and health professionals in their training in order to incorpo-rate into the labor market citizens with intellectual disabilities. The applica-tion provides technological support for cognitive skills training and is aimed at people with mild to moderate intellectual disability and who do not present physical difficulties that prevent the normal use of a mobile device. We use a development process that combines the iPlus methodology together with a collaborative user-centered approach. Suggested recommendations based on the results can improve the usability of the game developed.

3. Abstract
People with intellectual disabilities is one the concerns of current
societies
Non-Profit associations make efforts to improve the living conditions of
these citizens
We presents a heuristic evaluation of an educational mobile game
helping social workers and health professionals in their training, in
order to incorporate into the labor market citizens with intellectual
disabilities

4. Background
15% of the world’s population is affected by some physical, psychic or
sensory disability that hinders their personal development and social,
educational or occupational inclusion
WHO: Disability and health (Jan 2018)
https://www.who.int/news-room/factsheets/detail/disability-and-health

5. Background
Advanced information and communication technologies (ICT) are
facilitating changes in society, also in social and productive
relationships
Mobile applications as an emerging segment of ICTs are being a
fundamental element in supporting training activities
The applications must be usable, effective and accessible !

6. A Mobile Educational Application for Cognitive Skills
Training
The applications provide technological support for cognitive skills
training
Useful for people with mild to moderate intellectual disability
conducted by users which do not present physical difficulties that
prevent the normal use of a mobile device

7. A Mobile Educational Application for Cognitive Skills
Training
Application’s tasks

8. Heuristic usability – Materials and methods
Each expert
- became familiar with the application
- Made an individual evaluation considering the set of
heuristics evaluations and the severity’s levels
The results of each expert were merged for further
analysis

9. Results

10. Discussion
User support, user guidance and user effort were the most severely
criticized heuristics. This may have an origin in which there is no clear
guide and no feedback about the tasks that the user must perform
The experts founded inconsistencies in font styles and icons increasing
the cognitive workload imposed to the users
We recommend that all visual elements be reviewed so that redesigns
can be adjusted to a viewing standard.

11. Conclusion
The case study is developed from the need to train people with
intellectual disabilities to facilitate their integration into productive
activities, such as in a bakery
Future works should concentrate on performing new usability
evaluation studies, we will focus on making user experience in real
situations, with real users
