Abstract

The present invention relates to a method for a user to type text on a computer screen using wireless actuators attached to the user'"'"'s fingers. The image of a virtual keyboard and the user'"'"'s virtual fingers appears on the computer screen. As the user moves his fingers the virtual fingers on screen moves accordingly aiding the user to type. The actuators transmit symbol information to the computer indicative of a key virtually struck on the virtual keyboard by the user'"'"'s fingers. Text appears on screen. Virtual typing emulates typing on a physical keyboard. In other embodiments the actuators are coupled to other parts of the body for virtual typing.
