I tested my first intervention with one of the audience members from my target group which is adults aged 55+, the first intervention was just based around getting intial thoughts of the user about normal everyday interfaces that one might stumble upon, picked from the mobile apps used by the stats which show the type of apps used by adults aged 55+

While this intervention did give me some insights into the type of interfaces that might be preferred by this audience group as I asked them to give me an explanation about why they prefer one over the other, it also made me realise that it doesnt specifically point out the issues of these interfaces and might have, thus I decided to try another set up, which made users choose the same type of design in different layouts.

With this type of interface, there might be issues, as the person might just end up choosing the one which looks easier, rather than the one that might be better functionality wise. As the project progressed I have now decided to look at these from another perspective, which was via using principles of Art in design. Each question of the intervention tackles one of the principles of art, namely as Balance, Proportion, Contrast, Emphasis, Unity, Movement, & Harmony.
