Postural Ergonomic Risk Assesment of Augmented Reality User Interface on Smarthpones in Cosmetic Industry Advertising

Abstract

Augmented reality (AR) technology is widely used in marketing activities and promotional strategies so that many users or customers use it, including beauty products, which already offer many applications that are used as promotional tools. Augmented reality technology is accompanied by technological developments and the COVID-19 pandemic, especially among female customers in various groups, including teenage girls who use many cosmetic products daily. The use of this technology requires an evaluation regarding its use, where in this evaluation, an evaluation can be used in terms of ergonomics for the user using the ergonomics concept PERA (Postural Ergonomic Risk Assessment). This research aims to evaluate the postural risk regarding the level of use of augmented reality technology for beauty product applications used by female students when using AR applications on smartphones when accessing cosmetics industry advertising. This research was conducted on female teenage respondents among vocational school students who focused on skill competencies, namely the Skin and Hair Beauty Department at one of the private vocational schools in the Cilamaya-Karawang area. The sample for data collection in this study was by taking 30 respondents using a saturated sample. The results of this research indicate that there must be an evaluation regarding the level of ergonomics with the PERA measurement results ranging between 7.4 - 11.8, indicating that the AR user interface in the cosmetic industry advertising is in the high-risk category so that further improvements are needed in the future so as not to pose a risk of musculoskeletal disorders in teenagers. Thus, AR developers in the advertising industry must pay attention to the comfort of the user’s posture in terms of duration, smartphone weight, and grip strength when using AR applications.
