Systems and Methods For Shifting Haptic Feedback Function Between Passive And Active Modes

Abstract: Systems and methods for shifting haptic feedback function between passive and active modes are disclosed. For example, one disclosed method includes receiving a first signal from a sensor, the first signal associated with a mode of interaction with a graphical user interface; receiving a second signal associated with an interaction with the graphical user interface; determining a haptic feedback effect based at least in part on the mode of interaction with the graphical user interface and the interaction with the graphical user interface; and generating a haptic signal configured to output the haptic feedback effect.

Terminal Feedback Outperforms Concurrent Visual, Auditory, and Haptic Feedback in Learning a Complex Rowing-Type Task

Abstract: Augmented feedback, provided by coaches or displays, is a well-established strategy to accelerate motor learning. Frequent terminal feedback and concurrent feedback have been shown to be detrimental for simple motor task learning but supportive for complex motor task learning. However, conclusions on optimal feedback strategies have been mainly drawn from studies on artificial laboratory tasks with visual feedback only. Therefore, the authors compared the effectiveness of learning a complex, 3-dimensional rowing-type task with either concurrent visual, auditory, or haptic feedback to self-controlled terminal visual feedback. Results revealed that terminal visual feedback was most effective because it emphasized the internalization of task-relevant aspects. In contrast, concurrent feedback fostered the correction of task-irrelevant errors, which hindered learning. The concurrent visual and haptic feedback group performed much better during training with the feedback than in nonfeedback trials. Auditory feedback based on sonification of the movement error was not practical for training the 3-dimensional movement for most participants. Concurrent multimodal feedback in combination with terminal feedback may be most effective, especially if the feedback strategy is adapted to individual preferences and skill level.

Using force feedback to enhance human performance in graphical user interfaces

Abstract: This project uses aforce feedback joystick to enhance user interaction with standard graphical user interfhce paradigms. While typical joystick and mouse devices are input-only, force feedback controllers allow physical sensations to be reflected to a user. Tasks that require users to position a cursor on a given target can be enhanced by applying physical forces to the user that aid in targeting. For example, an attractive force field implemented at the location cf a graphical icon can greatly facilitate target acquisition and selection of the icon. It has been shown that fome feedback can enhance a users ability to perform basic functions within graphical user interfaces. ,

A Review of Surface Haptics: Enabling Tactile Effects on Touch Surfaces

Abstract: In this article, we review the current technology underlying surface haptics that converts passive touch surfaces to active ones (machine haptics), our perception of tactile stimuli displayed through active touch surfaces (human haptics), their potential applications (human-machine interaction), and finally, the challenges ahead of us in making them available through commercial systems. This article primarily covers the tactile interactions of human fingers or hands with surface-haptics displays by focusing on the three most popular actuation methods: vibrotactile, electrostatic, and ultrasonic.

Dynamic holographic video with haptic interaction

Abstract: A user is able to interact with and modify an electronic holographic image using a force-feedback (or haptic) device, which is capable of sensing and reporting the 3D position of its hand-held stylus and “displaying” appropriate forces to the user. Thus, a user can feel and modify specified shapes in the haptic workspace. The haptic workspace is precisely registered with the free-standing, spatial image displayed by a holographic video (holovideo) system. In the coincident visuo-haptic workspace, a user can see, feel, and interact with synthetic objects that exhibit many of the properties one expects of real ones, and the spatial display enables synthetic objects to become a part of the user's manipulatory space.
