Users of tablet computers should place their device on the table and tilt its screen, rather than have it flat on their lap, to avoid potentially painful hunching of the neck, a study suggested Wednesday.
"Tablet users may be at high risk to develop neck discomfort based on current behaviours and tablet designs," it warned.

A team led by environmental health researcher Jack Dennerlein of the Harvard School of Public Health asked seven men and eight women who were experienced tablet users to carry out tasks on an iPad2 and a Motorola Xoom.

Using a motion-analysis system, the team filmed the 15 volunteers as they worked on the tablet in four common configurations.
