25 Feb 2014TL;DR: A joy stick control assembly for operating a motor driven surgical instrument is described in this article, where a first switch assembly is movable supported by a housing and a second sensor is also movable with the first switch.
Abstract: A joy stick control assembly for operating a motor driven surgical instrument. In at least one form, the joystick control assembly comprises a first switch assembly that is movably supported by a housing. The first switch assembly may include a joystick that is movably mounted thereto such that pivotal movement of the joystick relative to the first switch assembly causes at least one corresponding control signal to be sent to at least one motor communicating therewith. The joystick control assembly may further include a second switch assembly that comprises a first sensor and a second sensor that is movable with the first switch assembly such that movement of the second sensor relative to the first sensor causes at least one other control signal to be sent to another one of the surgical instrument motors.

25 Sep 1996TL;DR: In this article, the authors present a method and apparatus for providing safe and low-cost force feedback peripherals for consumer applications, where a microprocessor is coupled to the host by a first interface bus, such as an RS-232 interface, and commands an actuator to apply a force to a user object such as a joystick, in response to host commands.
Abstract: A method and apparatus for providing safe and low-cost force feedback peripherals for consumer applications. A device microprocessor (26) local to an interface device (14) is coupled to the host (12) by a first interface bus (24). The microprocessor receives host commands from the host computer on the first interface bus, such as an RS-232 interface, and commands an actuator (30) to apply a force to a user object (22), such as a joystick, in response to host commands. A sensor (28) detects positions of the user object and outputs signals to the host on a second interface bus (25), such as a PC game port bus, separate from the firt bus. A safety switch (41) of the present invention disables the actuator when the interface device is not in use and enables the actuator when an amount of weight over a predetermined amount is placed on the joystick created by a user grasping the joystick.

TL;DR: A video game controller which attaches to the user's upper body allowing the user to play a video game by leaning the upper body in any direction, simulating the movement of a joystick is described in this paper.
Abstract: A video game controller which attaches to the user's upper body allowing the user to play a video game by leaning the upper body in any direction, simulating the movement of a joystick. The controller attaches to the user's upper back with an arrangement of straps and buckles. The tilt of the user's upper body is detected by an array of mercury switches with the resultant electrical signals being transmitted to the input of a video game. The specific angle of tilt required to actuate the mercury switches can be adjustable, thereby varying the degree of upper body movement needed to play a particular video game. Additional controls for the video game, such as a firing control, are provided by a hand held pushbutton attached to the controller via a flexible cord. Playing a video game using this arrangement results in vigorous exercise of the abdominal, back and lateral muscles.

TL;DR: A hand-held joystick has spaced-apart groups of accelerometers and is free to move or rotate on multiple axes as mentioned in this paper, with each group having three mutually perpendicular accelerometers, with each one producing an electrical signal responsive to linear acceleration along one axis.
Abstract: A hand-held joystick has spaced-apart groups of accelerometers and is free to move or rotate on multiple axes. Each group has, for example, three mutually perpendicular accelerometers, with each one producing an electrical signal responsive to linear acceleration along one axis. The signals are combined to derive a definition of acceleration of the joystick along the three mutually perpendicular linear axes and/or rotation about these axes. The combined signal is used by an electrical control system which provides input to a device being controlled. The signal to the device under control is responsive to the motion of the joystick.

15 Oct 2016TL;DR: Results indicated that Point & Teleport is a fun and user friendly locomotion method whereas the additional direction component degraded the user experience.
Abstract: With the increasing popularity of virtual reality (VR) and new devices getting available with relatively lower costs, more and more video games have been developed recently. Most of these games use first person interaction techniques since it is more natural for Head Mounted Displays (HMDs). One of the most widely used interaction technique in VR video games is locomotion that is used to move user's viewpoint in virtual environments. Locomotion is an important component of video games since it can have a strong influence on user experience. In this study, a new locomotion technique we called "Point & Teleport" is described and compared with two commonly used VR locomotion techniques of walk-in-place and joystick. In this technique, users simply point where they want to be in virtual world and they are teleported to that position. As a major advantage, it is not expected to introduce motion sickness since it does not involve any visible translational motion. In this study, two VR experiments were designed and performed to analyze the Point & Teleport technique. In the first experiment, Point & Teleport was compared with walk-in-place and joystick locomotion techniques. In the second experiment, a direction component was added to the Point & Teleport technique so that the users could specify their desired orientation as well. 16 users took part in both experiments. Results indicated that Point & Teleport is a fun and user friendly locomotion method whereas the additional direction component degraded the user experience.
