DeclutterAR: Mobile Diminished Reality and Augmented Reality to Address Hoarding by Motivating Decluttering and Selling on Online Marketplace

Hoarding behaviour is a widespread issue in which people have difficulty discarding or parting with their possessions. We present our work to address hoarding behaviours in people and promote the selling or donating of items that they no longer use or value through an online marketplace application (app). We introduce DeclutterAR, a feature linked to the marketplace app that uses Diminished Reality to remove real-world objects in the Augmented Reality (AR) scene, allowing you to visualise your “cluttered spaces” as “decluttered spaces”. DeclutterAR also allows users to sort removed objects to sell or give away. This work describes the system implementation and preliminary user study and discusses concepts of using Diminished Reality to motivate and support users in visualising target behaviours.
