Mercari R4D HCI team will participate in IEEE ISMAR 2022 conference which is held on October 17-21 in Singapore. We will present the following publications:

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

Key functions in the DeclutterAR: a. select the object for removal; and b. visualise the removal of clutter.


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.

The project will be presented at a poster session on Tuesday October 18th, from 17:30 to 18:30 SGT.

Workshop: Design and User Research in AR/VR/MR


Bektur Ryskeldiev (Mercari R4D), Joelle Zimmermann (Magic Leap), Mark Billinghurst (University of Southern Australia), Kai Kunze (Keio University), Jie Li (EPAM Systems), Julie Williamson (University of Glasgow)


The workshop will explore new techniques and processes for design, prototyping and testing in AR/VR/MR. How do we design and test useful and usable AR/VR/MR applications? How can we modify known design and research techniques and establish new techniques to suit immersive mediums? How might these processes vary based on the industry use case of the AR/VR/MR application? What are the metrics of success? We are interested in evaluation techniques that are qualitative, quantitative, computational/sensor-based, as well as rooted in ergonomics and human factors, and others! The workshop is of interest to conference participants and timely for ISMAR 2022, because as AR/VR/MR becomes more ubiquitous in industry, designers and researchers will need new methods to evaluate the usability and usefulness of immersive applications.

The workshop will be held on Friday October 21st, from 9:00 AM to 12:00 PM SGT (hybrid).


The IEEE ISMAR is the leading international academic conference in the fields of Augmented Reality and Mixed Reality. The symposium is organized and supported by the IEEE Computer Society, IEEE VGTC and ACM SIGGRAPH. The first ISMAR conference was held in 2002 in Darmstadt, Germany. The creation of the conference emerged from the fusion of two former academic events dedicated to this research field: the International Symposium on Augmented Reality (ISAR) and the International Symposium on Mixed Reality (ISMR).
