Touch screens are much lower and much closer than standard computer monitors at about the distance of the knee from the body while sitting.   The angle range must be adjustable from 20 degrees to 60 degrees.  The touch screen may be below the desk.

Scan your body for discomfort.  Monitor placement.   Move monitor through out the day.  Scan body for tension and adjust workstation and position to relieve the discomfort.  The display should be designed without speakers or other hardware under the display.

Jim Lavine at Mayo Clinic answers the question: What are the risks of sitting too much?

Excerpt:

One recent study compared adults who spent less than two hours a day in front of the TV or other screen-based entertainment with those who logged more than four hours a day of recreational screen time. Those with greater screen time had:

• A nearly 50 percent increased risk of death from any cause
• About a 125 percent increased risk of events associated with cardiovascular disease, such as chest pain (angina) or heart attack
