  • Universal tactile feedback system for computer video games and simulations
    Patent number: 6422941
    Abstract: A universal tactile feedback system for computer and video game systems is disclosed which provides real time tactile feedback to enhance a user's experience while interacting with a computer/video game or simulation. The tactile feedback system operates both in host-independent and host-dependent modes, thereby allowing the system to function even when no accomodation is provided by the game or simulation system that is being used. The host-independent mode is responsive to the audio signal that is typically generated by a computer or video game system while it is executing a game or simulation. The host-dependent mode is responsive to control commands specifically generated by a computer or video game system while it is executing a game or simulation.

  • Writing device for use with a pen-based data input system
    Patent number: 6066811
    Abstract: An improved writing device containing a stylus comprised of a self-lubricating material such as lignum vitae. Lignum vitae is a natural, wood product containing a waxy substance that reduces friction at the tip of the stylus as the tip is moved over a surface. A writing device having a stylus fabricated of lignum vitae is substantially less prone to scratch, mar or otherwise damage the surface of a pen-based data input instrument.
