Haptics research is by definition a very interdisciplinary field, with scientists and engineers building and evaluating tactile and haptic displays and exploring the domains in which the technology developed can be most optimally used. Central to this process are human user studies in which the displays are evaluated in terms of their capacity to present information to users and the sensitivity of...
Use of touch screens in cell phones, touch pads, tablet PS, and information kiosks are getting increasingly widespread. However, the touch screens available in the market today provide the user with limited haptic feedback, resulting in a less satisfying user experience. This workshop aims to bring academicians and scientists from industry together to discuss how haptics can be integrated into touch...
While haptic interaction with real, virtual, and remote environments is in the focus of the haptic community already since many years and implies the exchange of motion and force signals between two systems, haptic collaboration additionally requires the communication and negotiation of intentions, the building of mental models as well as the mutual adaptation of collaborating partners. Typical applications...
We propose a tactile enhancement structure inspired by hair follicle receptors. Unlike other receptors, part of the hair follicle receptor is exposed to the outside. Recent research has shown that skin hair contributes to perception of minute forces that cannot be perceived with glabrous skin. We considered how the skin perceives these minute forces. Our tactile enhancement device mimics the structure...
We show that vibrotactile feedback displayed through the steering wheel of a car can reduce the perceptual and cognitive load of the driver, leading to less distraction and fewer navigation errors. To demonstrate the concept, two vibration motors are mounted onto the steering wheel of a driving simulator and driving experiments are performed in virtual environments under two different sensory conditions...
This paper presents an intuitive approach of annotation based haptic interaction with traditional digital reading materials such as eBooks. The research targets to bring a multi-sensory interface consisting of perceptual, cognitive and vibrotactile interactions with the digital reading contents. It leverages a previously developed haptic jacket to receive haptic emotive signals wirelessly in the form...
A haptic icon is a short physical stimulus attached to a simple meaning, which provides information and feedback to a user. To scale the utility demonstrated for small icon sets to larger ones, we need efficient strategies to help users learn subtle distinctions among stimuli, in a modality for which they may not hold detailed descriptive percepts. This paper investigates the effect of naming haptic...
The vibration behavior of acoustic music instruments, as perceived through touch, is known to play an important role in the interaction between performers and music instruments. This research explores the relevance and utility of including a tactile simulation of this behavior in computer music interfaces, in a snapshot taken during early learning, and including tradeoffs of using this channel for...
This preliminary study investigated behaviorally the performance of a sample of young twins in a set of classical visuomotor tasks. The assessment was carried out using a small haptic interface used to produce force and record the hand trajectory during the execution of tasks requiring rapid and precise movements. The aim of the study was to evaluate the sensorimotor development across a wide age-range...
The field of research into Haptics excels for its multidisciplinary nature, reflecting the diffuse and complex nature of the underlying sensory systems, and also the importance and diversity of potential applications that the field can expect to unveil. It thus gives me great pleasure to welcome, on behalf of the EuroHaptics Society, all the disciplines represented at WorldHaptics 2011: The Fourth...
This paper investigates the tactile orientation discrimination of virtual, small-scale, patterned surfaces through a tactile display. The tactile display is an array of 4×4 vertically moving pins which can simulate the shape of small scale features. Its small size and low mass allow users to explore virtual surfaces freely and intuitively. The evaluation method consisted of measuring the orientation...
In recent years, tactile sensors have become an important interface for information devices. Our goal is to develop a simple and sensitive tactile sensor. We have proposed a reflection-image-based tactile sensor [1]. The key points of this sensor were its simplicity and use of an optical device. In this study, we propose a design of a distributed-force sensitive touch panel following the previous...
A system is proposed which enables users not only to operate computers by moving their hands in mid-air but also to feel touch feedback on their hands. The system consists of a PC, a markerless hand-tracker for input, and a non-contact tactile display for feedback. The tactile display utilizes ultrasound to produce tactile stimulation from a distance. It is based on a nonlinear phenomenon of ultrasound...
To augment tangible information into current social network systems (SNSs), this paper proposes an algorithm that generates force data from the user's hand gestures. The input modality defined in this paper is based on gesture information in the form of an acceleration profile in that at times it describes the current status of a user better than text-based content. For the physical representation...
We present a multi-finger 2-D haptic display device to potentially provide the opportunity of parallel processing of coarse haptic information, with the intended benefit of improving performance in 2-D haptic object recognition. Combined with a novel method for producing “texture” image representations, we found that multiple contacts does improve performance compared to a single contact in terms...
This paper focuses on the construction of a novel belt tactile interface and telepresence system intended for mobile robot control. The robotic system consists of a mobile robot and a wearable master robot. The elaborated algorithms allow the robot to precisely recognize the shape, boundaries, movement direction, speed, and distance to the obstacle by means of the laser range finders. The designed...
This paper presents a new subminiature impact type actuator which creates the haptic sensation in a mobile device. Recently, linear resonance actuators (LRA) are widely used. One of the key differences between an LRA and a traditional eccentric motor is that the LRA generates the vibrotactile sensation through resonance for minimizing response time. The strategy of operation near the resonant frequency,...
In our current work we explore the feasibility of using visuo-haptic augmented reality techniques for training and remote collaboration. Accurate calibration of system components is a key factor in this context. In this paper we deal with the calibration of the kinematic parameters of the haptic device. We compare a previously developed technique using an external optical tracker to a new approach...
In this paper, a novel haptic interface is proposed for general teleoperation of wheeled and tracked vehicle. The new mechanism of the proposed haptic interface shown in Fig. 1 not only allows human operator to easily tele-operate various types of target vehicles including car-like vehicles, mobile robots, tracked vehicles, but also improve the operators' perception of target vehicles' operating status...
Haptic cues take on meaning as a function of the context in which they are experienced. In interaction with objects in the physical environment, the context always includes a mechanical contact, at which point force and motion variables can be identified, and across which power may flow. In interaction with objects in a virtual or remote environment, it is not necessary for the contact across which...
