Phase 2: Speed Dating

The phase of our design leverage insight from prior brainstorming and interviews. With this information, we began ideating potential solutions to solve or improve experiences at the grocery store.

From our prior research, we began by identifying paint points and opportunities in the grocery shopping process.

We identified opportunity spaces that ranged from making a shopping list, to checkout. Based on the problem areas, we later brainstormed future solutions that integrate IoT.


To illustrate potential solutions, we sketched visions of how each solution would be implemented. Our ideas included quick checkout, dynamic pricing, improved navigation, and integrating shopping lists with recipes.

Expedited checkout concept. As shoppers place items in the cart, the cart is able to sense the items and calculate the total cost. At checkout, shoppers simply enter the checkout space and swipe their cards.
Dynamic pricing seeks to information shoppers in regards to information about where their food is coming from. By using information such as expiration and sell by date, stores can offer prices that change depending on quality.
In our navigation IoT concept, shoppers input their grocery list via mobile app. Each shopping cart knows this list as well as the fastest path to collecting all items listed. Colored navigation on the floor, specific to each shopping cart, leads shoppers to grocery items.
In this concept, each shopper’s fridge is able to track and store information about groceries used and needed. When at the store, shoppers receive information tailored to them about what items to purchase to make recipes specific to this information.

Storyboards & Speed Dating

For the next phase, we developed each concept into a more legible storyboard. Using visuals and text, these storyboards describe each concept more completely. We planned to utilize improved storyboards to walk test users through speed dating sessions.

During each speed dating session, we asked users to walk through each concept and express any thoughts they had. We then asked questions about users’ preferences, their inclination to use or not use a solution, and noted any clear pain points.

Expedited Checkout

Pros: fast check out; transparency of costs; less cost for grocery stores (less employees)

Cons: security could be compromised; privacy issues; loss of jobs

Dynamic Pricing

Pros: less waste

Cons: only applicable to produce; not much different from today’s current model (expiration labels)

Smart List

Pros: able to know what is already at home; possibilities with the smart fridge idea (3d scanning)

Cons: targets a specific group of shoppers who shop based on recipes

Improved Pathfinding

Pros: less time spent at the grocery store; less unnecessary items would be bought

Cons: directed only at shoppers with a list; too many colors needed
