A tactile feedback system for VE applications
Virtual Reality, 1996In this paper, research aspects on tactile feedback systems for Virtual Environments applications are presented. A theoretical approach dealing with the modelling of indentation and thermal functions to be utilized for the generation of tactile feedback stimuli is outlined. A description of the tactile effector components appropriately designed for the

Tactile feedback applied to computer mice
International Journal of Human-Computer Interaction, 1995Most computer systems use a mouse as the input device for menu selection, pointing, and manipulation of screen objects. The user can get visual information from the screen only about the position of the mouse and the action that was initiated. In contrast, during the manipulation of real objects, the visual channel is only responsible for giving ...

Improving tactile feedback with an impedance adapter
2013 World Haptics Conference (WHC), 2013Vibration motors are often used to generate tactile effects by exciting a mass at a given frequency and amplitude. The characteristic impedance of this vibrotactile device is not always in harmony with the impedance of the human skin. This impedance mismatch can result in poor energy transfer, necessitating larger motors and greater power consumption ...

Designing tactile feedback for piezo buttons
Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2011The present aim was to study the preference of tactile feedback stimulations given by non-physical (i.e., solid) piezo-actuated buttons. Participants (n=16) ranked 16 different tactile feedback stimuli varied by 4 output delays and 4 vibration durations. The results showed that the mean ranks of the stimuli differed significantly from each other.

Using Tactile Data for Real-Time Feedback
The International Journal of Robotics Research, 1990Object recognition through the use of input from multiple sensors is an important aspect of an autonomous manipula tion system. In tactile object recognition, it is necessary to determine the location and orientation of object edges and surfaces. We propose a controller that utilizes a tactile sensor in the feedback loop of a manipulator to track edges

Virtual Sequencing with a Tactile Feedback Device
2010Since the beginning of Virtual Reality many artistic applications were developed, showing how this technology could be exploited not only from a technical point of view, but also in the field of feelings and emotions. Nowadays music is one of the most interesting field of application for Virtual Reality, and many environments provide the user with ...

Slipping control through tactile sensing feedback
2013 IEEE International Conference on Robotics and Automation, 2013The paper presents a novel slipping control algorithm based on the exploitation of the tactile sensor integrated into the DEXMART anthropomorphic robotic hand. The Extended Kalman Filter (EKF) is used to solve in real-time the nonlinear model of the sensor, allowing to estimate the contact geometry variables and the friction coefficient. The innovative

Exploration of tactile feedback in BI&A dashboards
Proceedings of the 2017 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2017 ACM International Symposium on Wearable Computers, 2017This paper describes the development of a vibrotactile feedback system for the representation of piecewise linear graphs. It defines the basic idea of the system and describes the hardware and software in the background. It then shows how the vibration patterns, that are transmitted to the user via a wristband with two vibration motors, are calculated ...

Remote tactile feedback on interactive surfaces
2013Direct touch input on interactive surfaces has become a predominating standard for the manipulation of digital information in our everyday lives. However, compared to our rich interchange with the physical world, the interaction with touch-based systems is limited in terms of flexibility of input and expressiveness of output.
