08 Feb 2008TL;DR: In this article, the authors describe a system for utilizing touch-based input components that provide localized haptic feedback to a user, while the user scrolls around a click wheel, slides across a trackpad or touches a multi-touch display screen.
Abstract: Systems, methods, computer-readable media, and other means are described for utilizing touch-based input components that provide localized haptic feedback to a user. The touch-based input components can be used and/or integrated into any type of electronic device, including laptop computers, cellular telephones, and portable media devices. The touch-based input components can use, for example, a grid of piezoelectric actuators to provide vibrational feedback to a user, while the user scrolls around a click wheel, slides across a trackpad, or touches a multi-touch display screen.

20 May 2019TL;DR: This work uses self-supervision to learn a compact and multimodal representation of sensory inputs, which can then be used to improve the sample efficiency of the policy learning of deep reinforcement learning algorithms.
Abstract: Contact-rich manipulation tasks in unstructured environments often require both haptic and visual feedback. However, it is non-trivial to manually design a robot controller that combines modalities with very different characteristics. While deep reinforcement learning has shown success in learning control policies for high-dimensional inputs, these algorithms are generally intractable to deploy on real robots due to sample complexity. We use self-supervision to learn a compact and multimodal representation of our sensory inputs, which can then be used to improve the sample efficiency of our policy learning. We evaluate our method on a peg insertion task, generalizing over different geometry, configurations, and clearances, while being robust to external perturbations. We present results in simulation and on a real robot.

15 Jun 2004TL;DR: This paper uses image processing software and finger- and hand-based fiducial markers to track gestures from the user, stencil buffering to enable the user to see their fingers at all times, and fingertip-based haptic feedback devices to enableThe user to feel virtual objects.
Abstract: This paper presents a technique for natural, fingertip-based interaction with virtual objects in Augmented Reality (AR) environments. We use image processing software and finger- and hand-based fiducial markers to track gestures from the user, stencil buffering to enable the user to see their fingers at all times, and fingertip-based haptic feedback devices to enable the user to feel virtual objects. Unlike previous AR interfaces, this approach allows users to interact with virtual content using natural hand gestures. The paper describes how these techniques were applied in an urban planning interface, and also presents preliminary informal usability results.

TL;DR: This article gives an overview of research performed in the field of haptic information feedback during minimally invasive surgery (MIS) from 1985 to present and shows that currently, haptic Information feedback is rare, but promising, in MIS.
Abstract: This article gives an overview of research performed in the field of haptic information feedback during minimally invasive surgery (MIS). Literature has been consulted from 1985 to present. The studies show that currently, haptic information feedback is rare, but promising, in MIS. Surgeons benefit from additional feedback about force information. When it comes to grasping forces and perceiving slip, little is known about the advantages additional haptic information can give to prevent tissue trauma during manipulation. Improvement of haptic perception through augmented haptic information feedback in MIS might be promising.
