Amazon:
Just Walk Out
In 2022, I led a project to elevate the retail experience at cashierless physical stores using Amazon's Just Walk Out technology. The work optimized signage to explain how JWO works, build trust and confidence in the technology, excite shoppers, and keep them coming back.
Changing
the mental model
With traditional ways of shopping firmly established in people’s minds, an experience such as JWO, where familiar touchpoints and procedures are absent, can lead to hesitation or reluctance. A key goal was to define mechanisms that would help change customers’ mental models.

Interception mechanism

Provides shoppers with relevant information before or during their interaction with the store. It relies on shoppers noticing and engaging with signage without an explicit need.

Correction mechanism

Provides shoppers with relevant information when they experience a barrier or an error due to the inconsistency between their mental model and how JWO actually works. It relies on shoppers actively looking for information to help them resolve an issue.

An integrated map of the shopper journey—incorporating habits and needs, desired actions and outcomes, and in-store processes—helped to create a coordinated system of touchpoints that correspond to the mechanisms for changing customers’ mental models, while providing consistent, clear, and concise communication.

Guidance system taxonomy

The guidance system was broken down into five distinct categories classified by function. By differentiating understanding from immediate directions, acknowledgment from emotional support, this approach helped to align messaging, tone, hierarchy, appearance, and placement of signage.

Messaging formula

The unfamiliarity, uncertainty, and initial lack of confidence in JWO increase the shopper’s need for both instructions and understanding of how the technology works. This meant that the guidance system had to not only explain what actions are expected of shoppers and how to perform them, but also why they are necessary, and how they work.

Considering key
experience factors
Successfully catching a customer's attention at the right location, at the right moment, required addressing a range of physical constraints, relationships between touchpoints, and user accessibility needs.
“Self-containment” is the most crucial concept for an enhanced in-store experience. Given the variety of potential paths through a store, different layouts, unique shopping intentions, and individual behavior, certain touchpoints must communicate critical information without relying on others.

Self-containment

In-storeIf the shopper is buying just one item, guidance information needs to be available to them regardless of which shelf they pick the item from.

Self-contained segments

To reinforce new behaviors and boost confidence, critical messaging needs to be repeated frequently, while guarding against overuse that might cause shoppers to tune out.

The range of factors considered included viewing distance, importance, location, surfaces, orientation, placement height, coordination, self-containment and omnipresence. These considerations provided an overarching direction and the foundation for any further work on signage, or refinements to the JWO guidance system.
Putting hypotheses
to the test
Several rounds of qualitative research took place with a variety of shoppers, to measure their understanding of the JWO shopping model, and their level of confidence using it.

Researchers escorted participants through the full shopping experience. Each shopper provided feedback through a combination of task-based walkthroughs, and open questions.

Shoppers were also asked to choose which design elements enhanced their understanding of how to use JWO, and which increased their confidence to use it.

Delivering the core
of the system
Designs and messaging that were tested and refined—and some untested examples that could be useful beyond stadiums and arenas—were broken down across key areas of the store, with detailed explanations of the logic and rationale behind each.

Entry experience

Around and at entry points is the first exposure most shoppers have to a JWO store and it is paramount that signage engages them, educates them, and explains the experience so that they are excited and confident to enter.

Storefront wall & display

As the first and most prominent touchpoint seen by the shopper, it carrier information that fulfills a number of critical functions to raise awareness and confidence—from branding and marketing, to directions on how to use the store, to important regulatory and legal details.

Entry gate exterior

While the storefront wall is prominent, it may be obscured or missed in busy environments. This makes it critical that the entry gate provides the shopper with immediate instructions and some understanding of how a JWO store works.

Authentication terminal

Given the multitude of authentication methods offered to the shopper, the device uses universally-recognized icons and clear prompts to enable the shopper to quickly identify the reader matching their payment method and interact with it.

Shelf-talkers

Used for messages that reinforce the shopper’s understanding of the value proposition and how JWO works, underscore availability of associate support, and remind them of specific rules and requirements.

Exit experience

Being one of the biggest bottlenecks due to the absence of familiar barriers (such as cashier), the exit is designed to work in tandem with other touchpoints throughout the store to normalise the novel experience.

Receipt kiosk

Comprised of two touchpoints—a poster and takeaway card—to accommodate the shopper with more time to input their details, and the shopper rushing to leave the store.

Exit pedestal pop-up

Conveys critical information prior to departure. Even if the pop-up is in close proximity to the receipt kiosk, keeping the takeaway cards at the exit can help to reduce congestion.

The work also demonstrated how the guidance system and signage touchpoints can be distilled to a concise set of specifications, instructions, and templates compiled in an accessible format for merchants fitting out branded JWO stores.
Rollout and real-life
testing
Amazon has taken the messaging and touchpoints into real-world testing at JWO stores in stadiums and arenas across the United States.
