Research
Research findings
We shared an online questionnaire with the film fan community on Reddit and followed up with interviews.
23 respondents completed the online questionnaire
Finding your seat in the dark with a full tray is difficult. I have spilled my drink a few times.
Persona
Who we designed for
One of the project's two personas. The other, Emily, goes to the cinema with her partner.
Richard
42 years old · Prague · father
"Quiet film evenings bring the family together."
Goals
Enjoy films with his wife and children, and order snacks without missing part of the film in a queue.
Frustrations
Keeping the children calm in the snack queue. There is little time between arrival and the start of the film to buy snacks for everyone.
Situation
Richard arrives at the cinema late and tired, and struggles to keep the children calm at the snack counter.
Competitors
Competitor analysis
We looked at how major cinema chains handle ordering.
| PLATFORM | STRENGTHS | WEAKNESSES |
|---|---|---|
| AMC Theatres | Delivery to your seat, loyalty programme. | Complex website navigation. |
| Showcase Cinemas | A wide selection and interesting offers. | Inconsistent website layout. |
| Cineplex | Advance ordering and mobile tickets. | Few food photographs. |
Iterations
Changes after testing
Usability testing showed where the new ordering process needed explaining and where it could be faster.
A short explanation
A notice explains how the feature works so people can learn it quickly.
Quick ordering
We added a button to order favourite snacks in one click.
Filters within reach
We moved the filters to the bottom navigation to make them easier to reach.
