Yesterday I organized a workshop with eleven interaction design students to explain how keyboard navigation and voice assistant technology works.
After teaching them how to use voice over / narrator shortcuts, the task was to navigate through SNCF connect website without screen and try to book a Lyon Marseille ticket for next Saturday under 40€, with an assistance dog during the travel.

Only one succeeded after an hour but didn't find where to put the dog🐕‍🦺⁉️. Three students from Singapour didn't find how to put the website in English on the main page after closing three pop-ups in French.

They shared their experience at the end, wrote down how they felt, they were mostly frustrated, exhausted, pissed off at not being able to do a task they usually do under 10min

@MoritzBrouhaha this is a problem with many sites especially for those with disabilities and where the users' language isn't the website's principle language (and sometimes when not written in English).

These are effects from poor requirements, poor coding and often sites churned out rapidly to insufficent budget. The JS based code monkey sites frequently awful to navigate and data heavy.

Your results are not surprising. You may want to explain to the student who wrote "pissed", they probably should add off afterwards. Pissed, in many English speaking countries, means drunk, pissed off is annoyed, grumpy...
