A fixed or mobile image capturing device, coupled to a first computer, is remotely controlled over a global computer network by a second computer, and obtains a digital image of a scene. The first computer acquires a digital elevation model of the scene, which is data for creating a three-dimensional perspective model of the scene in two dimensions based on data corresponding, and registers the image with the digital elevation model. The registered digital image is provided to the second computer over the global computer network. When a user at the second computer points to an area of the registered image, the first computer augments the image provided with at least some information corresponding to the area pointed to.

A self-powered computer-pointing device includes a housing and a roller ball accommodated within the housing. At least a portion of the roller ball is exposed through an opening in the housing to allow the roller ball to contact a surface on which the computer-pointing device rests. Movement of the computer-pointing device across the surface imparts rotation of the roller ball. A sensing mechanism senses movement of the roller ball and generates x-y movement signals corresponding to movement of the computer-pointing device across the surface. The sensing mechanism conveys the x-y movement signals to a host computer. A power generating mechanism is coupled to the roller ball and converts rotational movement of the roller ball into electrical energy that is used as power by the computer-pointing device.

The present invention includes a system for and methods of storing and comparing computer generated vector lines through an insecure or a secure communication channel. A continuous vector line (CVL) identifier includes from an ordered collection of 2 or more points. Using an input device (such as computer keyboard, finger, soft keypad, or any other input from body movements or input from electrical current or impulses, or input from human or mechanical sound waves) to a physical machine, or through a token (such as credit card, USB token, which can be carried around by user), a user enters and sends their unique identifier and reference code (such as a personal identification number (PIN), and / or password or other secret code) to the physical machine by making a contact or contact-less to the computer system. As part of the enrollment process the user inscribes a pre-determined set of continuous vector lines (CVLs). The CVLs include data points that are collected from any computer pointing device, such as a mouse, stylus or a digitizer tablet, in a specific format, using a push down anatomical technique and are sent to local active content (such as a library, or a program, or an add-on to the Internet browser such as ActiveX) or a remote server for further analysis of the two CVL's. A user should go through an Enrollment and Verification process to capture the data points and this process uses a two factor authentication and a verification scheme. The collected data points that represent a CVL profile made previously is kept in a database, registry, or memory that can be encrypted and accessed by using a reference number or other unique identifier. Access is either locally or remotely through any wired or wireless medium such as the Internet, Secure File Transfer Protocol (SFTP) server, cellular network or other communication connection to enable the comparison of a newly generated CVL identifier to the CVL profile generated previously.

In a computer having a processing unit, a coordinate input device such as a mouse and a display screen, a video image of a cursor or pointer can be moved and positioned on the screen by moving the mouse. The speed of the pointer is changed according to the amount of movement or travel distance of the mouse or pointer. As the mouse or pointer is moved farther from an initial position, the speed of the pointer is increased. When the mouse is stopped or its speed is reduced below a given value, the process stops and restarts with the next movement of the mouse. In one embodiment, the pointer moves at a low speed in fixed relation with the mouse for a first part of the movement of the mouse or pointer. The increase in pointer speed starts after the completion of the first part of the movement. In another embodiment, the speed of the pointer is increased gradually or stepwise form the beginning of the movement of the mouse or pointer.

A computer pointing device, such as a mouse or trackball, includes a reverse cantilever button assembly to match strength-related variations in user hand size. In one embodiment a button assembly is built with two cantilever beams, the fulcrums for each beam being at opposite ends of the button assembly. The stiffness of the two beams can be selected to obtain an increasing, decreasing, or constant force profile necessary to activate the associated electronic switch as one moves along the external surface of the button assembly from the palm end toward the fingertip end. An increasing force profile provides lower actuating force for operators with smaller hands, while providing greater tactile feedback for operators with larger hands.
