Background:We present  the results of the redesign process based on user experience (UX) of a cognitive stimulation web laboratory (labpsi.mdp.edu.ar/ejercicioscognitivos) in elderly people with Mild Cognitive Impairment (MCI).Research based on the analysis of user experience includes the observation of affectivity and significant experiences when using a product as well as motivation.The amount a person achieves when using a productWith the aim of making the product more accessibleMethods:Twenty MCI participants from Mar del Plata, Argentina, were included with an average age of 75.5 years and an average ACE-III (Bruno et al. 2020) score of 79.7. They were divided into pre-redesign (Pre-G) and post-redesign (Post-G) groups. They used LABPSI on tablets and cell-phones. We recorded objective and subjective metrics within the Mobile Goal Questions metrics framework (Hussein, 2012). Participants completed three tasks on LABPSI, with 13 objective measures recorded, including correct steps, mistakes made, and correct steps within a specific time frame for tasks 2 and 3. Subjective measures were collected through a satisfaction questionnaire, assessing perceived usefulness, satisfaction with image and text sizes, and intentions to recommend it. Measures were collected before and after the lab´s redesign with different samples to avoid a learning effect.Results:A Mann Whitney U test compared objective metrics before and after the redesign for both groups. The Post-G showed significant improvements in all measures in tasks 1 and 2 (p<.05), and in most measures in task 3 (p<.05), except for task 3 completion, which was close to significance (p=.064). Satisfaction measures, with a maximum score of 36 points, showed an average of 28.9 for Post-G and 25.9 for Pre-G. Participants expressed positive attitudes toward learning and using new technologies, with 90% of Post-G intending to use LABPSI again, compared to 70% of Pre-G, and 90% of Post-G intending to recommend it to others, compared to 30% of Pre-G.Discussion:The results emphasize the importance of UX analysis in adapting technologies for older people with and without MCI. LABPSI´s modifications improved performance in this population.
