PoX Mobile App



To increase their market share, Chexology decided to explore ideas for a mobile friendly solution that would give them the opportunity to triple the market size and go after other users that required mobility.

Chexology used the valet parking interaction as an example to prove this concept.



  • The ability for attendants to scan items into the system without the need fixed location

  • Attendants should be able to connect more than one image to a scanned item

  • Allow attendants to enter information without a fixed entry flow


I began the design process with the Object Oriented UX (OOUX) approach. OOUX is a design language model organized around objects rather than “actions” and data rather than logic. This approach defines and differentiates objects, structures and prioritizes object elements, helps find the sweet spot of complexity and gives everyone a common understanding. 

Objects are derived directly from the goals of a system, and goals should be derived from research.

After the goals (objects) are defined they need structure, during the element audit step, the core content, metadata and relationships with other objects are defined. A CTA inventory, lists the actions believed that the user would want to do with each object. 



user flow

Taking in consideration the work previously done, this flow shows the high-level relationship of the objects and elements within each other.




The OOUX process and app flow identifies the needs for each screen, when moving on to the wireframes, placement and hierarchy of each object are the main focus as well as trying to find patterns between each element that can be used throught the application.
