Effect of control interface implementation on operation of a multi degree of freedom telerobotic arm
… Canadarm2 is difficult, involving a complex twin-joystick interface. Although astronauts on EVA often stand fixed at the end of the robot arm for stability, EVA astronauts cannot control the arm themselves, instead relying on teleoperation by a second astronaut inside the ISS. A study was …

An Electromechanical Synchronization of Driving Simulator and Adaptive Driving Aide for Training Persons with Disabilities
… train disabled persons but none of them have joystick-enabled training that controls both steering, gas and break pedal. This necessitates the design of a method and a system which helps a person with disabilities learn how to operate a joystick-enabled vehicle, by using a combination of an …

Driving to Learn. The process of growing consciousness of tool use - a grounded theory of de-plateauing.
… training people with cognitive disabilities in a joystick-operated powered wheelchair utilizing the grounded theory approach. Theoretical sampling led the concomitant collection and analysis of data. During a period of 12 years, 45 participants with profound cognitive disabilities, aged 12 months …

Multi-touch through-the-lens drone control
… way people currently control them is using a joystick that controls the pitch, yaw, roll and throttle of the drone. With the joystick, a user has to think not only in terms of the desired image but also how the drone needs to move in order to capture it. We implemented a gestural system that …

Navigating Virtual Environments At Scale
… techniques like Walking-in-place, teleportation, joystick etc. should be used in-conjunction with real walking input or just by themselves. We present studies on two alternative navigation techniques (Legomotion & Dash ) that enable immersive, efficient and scaleable virtual navigation.Combining …
