The invention herein primarily concerns computer interfaces, particularly those that may be used by senior citizens or others who are not familiar and even adverse to computers as they are utilized today. Applications of use to such persons are also disclosed, particularly in the areas of most concern to large segments of the population such as Health Maintenance and Medical, Home Control, and Communication (email and telephony). It is primarily based on TV cameras interfaced to computers via common interfaces such as USB2, Fire wire, or WiFi, which are used to sense common, and familiar paper pages and books of pages.
