VR Sickness Benchmark System


Tackling VR Sickness: A Novel Benchmark System for Assessing Contributing Factors and Mitigation Strategies through Rapid VR Sickness Induction and Recovery


This research intro­duces a novel VR sick­ness bench­mark system, designed to address the lack of stan­dard­ized tools for assess­ing and mit­i­gat­ing VR sick­ness. It aims to rec­tify the incon­sis­ten­cies and lim­i­ta­tions preva­lent in exist­ing VR sick­ness assess­ment and mit­i­ga­tion meth­ods, thereby facil­i­tat­ing more effec­tive and com­pa­ra­ble cross-study analyses.

This bench­mark system, cre­ated using Unity 3D, fea­tures two dis­tinct VR envi­ron­ments, small and large, designed as figure-eight racing tracks through roller-coaster-like move­ments. Key design ele­ments to induce VR sick­ness includ vary­ing speeds, direc­tional changes, ele­va­tion shifts. pas­sive par­tic­i­pant move­ment, and enhanced optic flow with visual ele­ments. The system also includes an in-VR sick­ness rating tool for real-time feedback.

Our research stud­ies aim to eval­u­ate the effec­tive­ness of four com­monly dis­cus­sion VR sick­ness mit­i­ga­tion tech­niques in the envi­ron­ments, aimed at (1) val­i­dat­ing the bench­mark system’s capa­bil­ity to induce and reduce VR sick­ness in a con­trolled manner, ensur­ing tem­po­rary, man­age­able symp­toms with rapid recov­ery times. This aspect is cru­cial for eth­i­cal research con­duct and par­tic­i­pant safety; and (2) sys­tem­at­i­cally eval­u­at­ing and com­par­ing dif­fer­ent VR sick­ness mit­i­ga­tion tech­niques, con­tribut­ing to stan­dard­iz­ing VR sick­ness assess­ment and enhanc­ing the reli­a­bil­ity and com­pa­ra­bil­ity of VR research. The bench­mark system’s adapt­abil­ity across var­i­ous research dimen­sions makes it a valu­able tool for VR devel­op­ers and researchers, enabling effi­cient test­ing of a wide range of para­me­ters and design iterations.

This project is part of Rose Rouhani’s MSc thesis, here’s Rose pre­sent­ing on the VR Sickness Benchmark Project:

Videos of the small and large envi­ron­ments, with the VR sick­ness mit­i­ga­tion tech­niques imple­mented in each can be found in this YouTube playlist. Below is one exam­ple for the Dynamic FOV reduc­tion method, all of them are listed on our YouTube playlist.

A link to a freely avail­abe open sources Unity ver­sion of the VR Sickness Benchmark will be posted soon — please con­tact us if interested.
