Scan It: Visual Search Mobile App
Amazon Scan It is a feature in the Amazon mobile app that uses visual search technology to help customers find products using the camera on their mobile device. Collaborating with product managers and engineers, I created two prototypes of the mobile app for user testing.
Before the redesign of the Scan It feature, I created user personas to guide the goals and behavior of Amazon customers. The personas were synthesized from data collected from interviews with customers.
Scan It Prototype #1
Prototype #1 starts with a strong focus on the visual. I created a design language using icons to help guide the customer to better scanning by providing a view finder, responsive fireflies, and helpful tips. Features inclued in the prototype are access to customer's history, recommendations, and upload a photo.
Delight is introduced by the animated Amazon logo at the top that appears as if it is speaking the tips to the customer.
Scan It Prototype #2
Prototype #2 relies on swipe gestures. The first screen is the home screen with scanning feature. Swiping up invokes 'Upload a photo', accessign the customer's photo library. Swiping down invokes the Recommendations screen that recommends products on Amazon based on previous purchases and image scans. Swiping left or back invokes the History screen. This screen is a collection of past scans the customer made in previous sessions. Swiping right invokes Gift Card scanning, Barcode scanning, and anything else (i.e. beauty products and fashion).
Scan It Usability Study #1
For the initial usability study, we (myself and user researcher) followed Amazon customers to several stores as they used the original Scan It feature to do their shopping. The two goals of the study were to get better understandings of how they use the feature and what aspects of the feature meets or does not meet their needs.
After the study, we processed the data and decided on refinements to the Scan It feature. Once we decided on the important improvements, we began sketching new interfaces. The redesigns became the testing prototypes for the second usability study.
Scan It Usability Study #2
For the second usability study, we (myself and design team) created a store shelf in the UX Lab and had the participants (all Amazon customers) scan each item using the different Scan It prototypes.
For the study, we had 9 participants. In our team, we had a moderator, a camera person, several note takers and observers. The observers were in the next room watching the usability tests.
The results from the usability studies were then put into both quantitative and qualitative data and informed all of the refinements to the Scan It feature.
