Challenge Focus

We want to explore keeping our customers close and active by using “XR in a hybrid environment”, where we can showcase products and provide excellent customer support in-store and at home.

As the world works to find a new post-pandemic normal, we believe that people will be incentivized to shop and seek support through the intersection of online and in person experiences. Technology – specifically augmented, virtual and mixed reality technologies (collectively XR) – will make it possible for us to work, learn, and interact with one another, while remaining physically distant.
