Scaling Robotic Controls and Displays for Army Soldiers [PDF ebook] 

Scalability has been given many different definitions, depending upon the background of the person defining it, the technology being considered, and the operational use of the technology. Typically, when interface designers talk about scalable interfaces they are referring to a design that ensures that development takes into account the requirement to change over time. Without this type of scalability, interface designs require a complete renovation when a small change is needed in the application. This book examines the process of scaling robotic controls and displays for army soldiers.
