The mobile devices are very popularly used in our business, study, leisure and daily lives. Text messaging is the most frequently used function of smart devices such as smartphone and tablet. Users use their fingers for touching, double clicking and dragging on the devices. We measured EMG on right flexor cardi radialis (RFCR) and right extensor carpi ulinaris (RECU) for sitting, lying on the belly, and lying on the back textual message input postures on the mobile devices. The participants also evaluated the textual input postures by Borg’s RPE scale. The study found smartphone requires less ergonomic workload than tablet. Sitting posture is ergonomically better than lying face down and lying on the back posture when using the mobile devices.
