In order to study the cross-effects of interaction task, target size and target location on the accuracy of egocentric peripersonal distance cognition, a 2 \u00d7 5 \u00d7 9 \u00d7 5 asymmetric experiment was designed and carried out. There were two kinds of interaction tasks, five kinds of interaction target widths and nine kinds of spatial locations set to estimate the five egocentric peripersonal distances. Based on the experimental data, with interaction task, target width and the actual spatial location as independent variables and virtual interaction location as a dependent variable, the mapping model between the actual physical location and virtual interaction location of different interaction targets was constructed and evaluated by multiple linear regression method. The results showed that the prediction model constructed by stepwise regression method was simple and less computationally intensive, but it had better stability and prediction ability. The correlation coefficients R2 on xp, yp and zp were 0.994, 0.999 and 0.998, RMSE values were 2.583 cm, 1.0774 cm and 1.3155 cm, rRMSE values were 26.57%, 12.60% and 1.15%, respectively. The research of relevant experiments and the construction of models are helpful to solve the layout optimization problem of virtual interactive space in the Digital Twin system.<\/jats:p>","DOI":"10.3390\/sym14102178","type":"journal-article","created":{"date-parts":[[2022,10,18]],"date-time":"2022-10-18T00:31:01Z","timestamp":1666053061000},"page":"2178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Construction of Virtual Interaction Location Prediction Model Based on Distance Cognition"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0580-713X","authenticated-orcid":false,"given":"Zhenghong","family":"Liu","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Guiyang University, Guiyang 550005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huiliang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Manufacturing Technology of the Ministry of Education, Guizhou University, Guiyang 550025, China"},{"name":"Department of Product Design, School of Fine Arts, Guizhou Minzu University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Lv","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Manufacturing Technology of the Ministry of Education, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qipeng","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Guiyang University, Guiyang 550005, China"},{"name":"Key Laboratory of Advanced Manufacturing Technology of the Ministry of Education, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiaoqiao","family":"Xiong","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Manufacturing Engineering, Faculty of Engineering, Universiti Putra Malaysia, Selangor 43400, Malaysia"},{"name":"Department of Mechanical and Electronic Engineering, Guizhou Communications Polytechnic, Guiyang 551400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,17]]},"reference":[{"key":"ref_1","first-page":"340","article-title":"Research on VR spatial cognition based on virtual reproduction behavior","volume":"27","author":"Zhao","year":"2020","journal-title":"Chin.
