The inherent nature of laptops - with a connected keyboard and screen, defies most if not all accepted recommendations of ergonomic computing
Research on laptop computing is consistently demonstrating a relationship between laptop computing and poor posture, increased neck angle, tilt and stress, and lower productivity
There is a rapid growing body of information from experts as Dr. Alan Hedge of Cornell University, the US Center for Disease control, Chris Grant, PhD, CPE, and the University Computing Research Center in Ergonomics at Texas A&M University.
The following is a summary of their recommendations
1. Occasional User / Road Warriors
Find a comfortable chair to sit back in
Angle screen to minimize neck deviation and head tilt
Position laptop in lap for most neutral wrist position
2. Frequent Users
Elevate laptop screen at or near eye level to lessen neck angle and head tilt
Use a separate keyboard and mouse. Position both at elbow height
Maintain a comfortable viewing distance: 18-30 inches
Angle screen to be perpendicular to line of sight
Take regular rest break - up to 5 minutes / hour
