Ten male participants aged 16&ndash;24, with</i><i> normal BMI and accustomed to playing Mobile Legends</i><i> for at least 2 hours daily, were involved. The study was conducted at the Ergonomics Laboratory</i><i> Department of Mechanical</i><i> and</i><i> Industrial Engineering, Gadjah Mada University. All subjects had normal vision verified by a</i><i> Snellen card test. Devices</i><i> used included an iPhone 11 Pro Max, a gaming chair, a beanbag, and</i><i> lazy glasses. Discomfort was assessed using a Borg scale</i><i> questionnaire, eye fatigue with the</i><i> Visual Fatigue Index, and gaming experience via the Game Experience Questionnaire. Neck</i><i> and joint angles were measured using inertial motion capture. Results showed that seating position and repetition significantly</i><i> affected discomfort (p< 0.05), with wrist posture also influenced by</i><i> chair type (p< 0.05). Lazy glasses increased eye strain</i><i> (p< 0.01) and affected neck posture (p<</i><i> 0.05). Repetition significantly contributed to eye fatigue (p< 0.01). It is recommended</i><i> to avoid lazy glasses and prefer gaming chairs for better ergonomic comfort and experience.</i></span></span></span></div> </div> </div> </div> Mobile gaming,Lazy Glasses,Physical Measurement 27 35 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-3031-8&slc_lang=en&sid=1 Dwi Kristanto dwikristanto1999@mail.ugm.ac.id 1800319475328460015113 1800319475328460015113 Yes PhD student of Department Mechanical and Industrial Engineering, Universitas Gadjah Mada, Indonesia Kafa Asyiradinta 22106060057@student.uin-suka.ac.id 1800319475328460015114 1800319475328460015114 No Bachelor student of Department Industrial Engineering , Universitas Islam Negeri Sunan Kalijaga, Indonesia
