Effects of Augmented Reality on Humans

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | Measured just before and immediately after every 30 minutes series (repeated three times) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Heart rate | Heart rate during the different tasks and test session | 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) | Measured just before and immediately after every 30 minutes series (repeated three times) | 
| Memory | 5 words memory test | Measured just before and immediately after every 30 minutes series (repeated three times) | 
| attention | Stroop test | Measured just before and immediately after every 30 minutes series (repeated three times) | 
| subjective perceived exertion | difficulty of the tasks using a visual analogic scale | Measured just before and immediately after every 30 minutes series (repeated three times) | 
| subjective pain perception | pain perceived (visual analogic scale) and the location if some pain sensation | Measured just before and immediately after every 30 minutes series (repeated three times) | 
| subjective fatigue perception | perceived fatigue (visual analogic scale) and the location in case of fatigue feeling | Measured just before and immediately after every 30 minutes series (repeated three times) |
