Nowadays, augmented reality (AR) has gained attention but little is known concerning its repercussion in individuals when considering some mental and physiological aspects. Therefore, the aim of this study was to investigate the effects of AR glasses on some cognitive and physiological functions in an attempt to determine its safety for workers.
Twelve volunteers were tested during two separate randomized sessions: one with AR glasses (ARGlass) and one in normal condition (Normal). Participants had two perform different tasks of a 90 minutes total duration. Before, during and after these tasks, two feet balance, one foot balance, precision balance, stroop and memory tests were performed. Also, heart rate and electromyographic activity of some muscles were recorded. Finally a survey was filled to determine, for example fatigue, pain or comfort.

Voluntary activation using electromyography of upper and lower limb muscles
The mean electromyographic activity of trapezius, deltoideus, biceps brachii, latissimus dorsi, soleus and tibialis anterior muscles will be measured using surface electrodes
Time frame: Measured just before and immediately after every 30 minutes series (repeated three times)
Heart rate
Heart rate during the different tasks and test session
Time frame: Measured just before and immediately after every 30 minutes series (repeated three times)
Balance
Two feet, one foot and precision tasks balance (center of pressure displacement)
Time frame: Measured just before and immediately after every 30 minutes series (repeated three times)
Memory
5 words memory test
Time frame: Measured just before and immediately after every 30 minutes series (repeated three times)
