TL;DR: This review focuses on haptic methods that display data that can be used to present information, and consequently, the user gains quantitative, qualitative, or holistic knowledge about the presented data.
Abstract: There are many different uses for haptics, such as training medical practitioners, teleoperation, or navigation of virtual environments. This review focuses on haptic methods that display data. The hypothesis is that haptic devices can be used to present information, and consequently, the user gains quantitative, qualitative, or holistic knowledge about the presented data. Not only is this useful for users who are blind or partially sighted (who can feel line graphs, for instance), but also the haptic modality can be used alongside other modalities, to increase the amount of variables being presented, or to duplicate some variables to reinforce the presentation. Over the last 20 years, a significant amount of research has been done in haptic data presentation; e.g., researchers have developed force feedback line graphs, bar charts, and other forms of haptic representations. However, previous research is published in different conferences and journals, with different application emphases. This paper gathers and collates these various designs to provide a comprehensive review of designs for haptic data visualization. The designs are classified by their representation: Charts, Maps, Signs, Networks, Diagrams, Images, and Tables. This review provides a comprehensive reference for researchers and learners, and highlights areas for further research.

26 Jul 2012TL;DR: The results indicate that the grip force control is significantly enhanced via the haptic feedback, however, the simultaneous display of two haptic channels does not enhance, but instead degrades, gripforce control.
Abstract: In this study, we hypothesized that haptic feedback would enhance grip force control of surface electromyography (sEMG)-controlled prosthetic hands for targeted reinnervation (TR) amputees. A new miniature haptic device, a tactor, that can deliver touch, pressure, shear, and temperature sensation, allows modality-matching haptic feedback. TR surgery that creates sensory regions on the patient's skin that refer to the surface of the missing limb allows somatotopic-matching haptic feedback. This paper evaluates the hypothesis via an sEMG-controlled virtual prosthetic arm operated by TR amputees under diverse haptic feedback conditions. The results indicate that the grip force control is significantly enhanced via the haptic feedback. However, the simultaneous display of two haptic channels (pressure and shear) does not enhance, but instead degrades, grip force control.

14 Mar 2013TL;DR: In this article, the authors present a system of the present disclosure that includes a sensor configured to detect user interaction with a touch surface and transmit a sensor signal associated with the user interaction.
Abstract: A system of the present disclosure may include a sensor configured to detect user interaction with a touch surface and transmit a sensor signal associated with the user interaction; a processor in communication with the sensor, the processor configured to: determine a position of the user interaction based on the sensor signal, determine a feature associated with the position of the user interaction, control a device associated with the feature, modify a display signal based in part on the user interaction, select a haptic effect to generate based at least in part on user interaction and the position, the haptic effect selected to simulate the feature, and transmit a haptic signal to generate the haptic effect, and a haptic output device in communication with the processor and coupled to the touch surface, the haptic output device configured to receive a haptic signal and output a haptic effect.

19 Jun 2000TL;DR: Virtual reality haptic programming requires good physical modeling of user interactions, primarily through collision detection, and of object responses, such as surface deformation, hard-contact simulation, slippage, etc.
Abstract: Haptics is a recent enhancement to virtual environments, allowing users to "touch" and feel the simulated objects they interact with. Current commercial products allow tactile feedback through desktop interfaces (such as the FEELIt/sup TM/ mouse or the PHANToM/sup TM/ arm) and dextrous tactile and force feedback at the fingertips through haptic gloves (such as the CyberTouch/sup TM/ and the CyberGrasp/sup TM/). Virtual reality haptic programming requires good physical modeling of user interactions, primarily through collision detection, and of object responses, such as surface deformation, hard-contact simulation, slippage, etc. It is at present difficult to simulate complex virtual environments that have a realistic behavior. This task is added to by the recent introduction of haptic toolkits (such as Ghost/sup TM/ or VPS). Current technology suffers from a number of limitations, which go beyond the higher production cost of haptic interfaces. These technical drawbacks include the limited workspace of desktop interfaces, the large weight of force-feedback gloves, the lack of force feedback to the body, safety concerns, etc. Not to be neglected is the high bandwidth requirement of haptics, which is not met by current Internet technology. As a result, it is not possible at present to have a large number of remote participants interacting haptically in a shared virtual space.

02 Mar 2001TL;DR: This paper has developed three novel user interfaces: GestureDriver, HapticDriver and PdaDriver, and presents the motivation for and design of each interface.
Abstract: Remote driving is a difficult task. Not only do operators have problems perceiving and evaluating the remote environment, but they frequently make incorrect or sub-optimal control decisions. Thus, there is a need to develop alternative approaches which make remote driving easier and more productive. To address this need, we have developed three novel user interfaces: GestureDriver, HapticDriver and PdaDriver. In this paper, we present the motivation for and design of each interface. We also discuss research issues related to the use of gesture, haptics, and palm-size computers for remote driving. Finally, we describe lessons learned, potential applications and planned extensions for each interface.
