kirigami keyboard inkjet printable paper interface with kirigami structure presenting Kinesthetic Feedback
Human Factors in Computing Systems, 2019Co-Authors: Zekun Chang, Kunihiro Kato, Kazuya Saito, Tung D Ta, Weiwei Jiang, Koya Narumi, Yoshinobu Miyamoto, Yoshihiro KawaharaAbstract:We propose a DIY process to produce customized paper keyboards with Kinesthetic Feedback that interact with touchscreens. The process is built using two techniques: kirigami and printable double-layered circuits. Our goal is to improve the extensibility and usability of various interfaces made with 2D paper substrates. First, Our kirigami structures provide Kinesthetic sensations whose z-directional key stroke is comparable to that of traditional keyboards. In order to design keys with appropriate stroke and reaction force, we adopted the Rotational Erection System (RES). Second, printable double-layered circuits allow users to easily adjust input layouts. This easy-to-customize keyboard can be especially useful for those who have specific requirements for input devices.

virtual muscle force communicating Kinesthetic forces through pseudo haptic Feedback and muscle input
User Interface Software and Technology, 2019Co-Authors: Michael Rietzler, Florian Geiselhart, Gabriel Haas, Thomas Dreja, Enrico RukzioAbstract:Natural haptic Feedback in virtual reality (VR) is complex andchallenging, due to the intricacy of necessary stimuli and re-spective hardware. Pseudo-haptic Feedback aims at providinghaptic Feedback without providing actual haptic stimuli butby using other sensory channels (e.g. visual cues) for feed-back. We combine such an approach with the additional inputmodality of muscle activity that is mapped to a virtual force toinfluence the interaction flow. In comparison to existing approaches as well as to no kines-thetic Feedback at all the presented solution significantly in-creased immersion, enjoyment as well as the perceived qualityof Kinesthetic Feedback.

conveying the perception of Kinesthetic Feedback in virtual reality using state of the art hardware
Human Factors in Computing Systems, 2018Co-Authors: Michael Rietzler, Florian Geiselhart, Julian Frommel, Enrico RukzioAbstract:Including haptic Feedback in current consumer VR applications is frequently challenging, since technical possibilities to create haptic Feedback in consumer-grade VR are limited. While most systems include and make use of the possibility to create tactile Feedback through vibration, Kinesthetic Feedback systems almost exclusively rely on external mechanical hardware to induce actual sensations so far. In this paper, we describe an approach to create a feeling of such sensations by using unmodified off-the-shelf hardware and a software solution for a multi-modal pseudo-haptics approach. We first explore this design space by applying user-elicited methods, and afterwards evaluate our refined solution in a user study. The results show that it is indeed possible to communicate Kinesthetic Feedback by visual and tactile cues only and even induce its perception. While visual clipping was generally unappreciated, our approach led to significant increases of enjoyment and presence.

A Modular Wearable Finger Interface for Cutaneous and Kinesthetic Interaction: Control and Evaluation
IEEE Transactions on Industrial Electronics, 2020Co-Authors: Francesco Chinello, Domenico Prattichizzo, Monica Malvezzi, Claudio PacchierottiAbstract:In this paper, we present a novel modular wearable interface for haptic interaction and robotic teleoperation. It is composed of a 3-degree-of-freedom (3-DoF) fingertip cutaneous device and a 1-DoF finger Kinesthetic exoskeleton, which can be either used together as a single device or separately as two different devices. The 3-DoF fingertip device is composed of a static body and a mobile platform. The mobile platform is capable of making and breaking contact with the finger pulp and reangle to replicate contacts with arbitrarily oriented surfaces. The 1-DoF finger exoskeleton provides Kinesthetic force to the proximal and distal interphalangeal finger articulations using one servo motor grounded on the proximal phalanx. This paper presents the wearable device as well as three different position, force, and compliance control schemes, together with their evaluations. We also present three human subjects experiments, enrolling a total of 40 different participants: the first experiment considered a curvature discrimination task, the second one a robot-assisted palpation task, and the third one an immersive experience in virtual reality. Results show that providing cutaneous and Kinesthetic Feedback through our device significantly improve the performance of all the considered tasks. Moreover, although cutaneous-only Feedback shows promising performance, adding Kinesthetic Feedback improves most metrics. Finally, subjects rank our device as highly wearable, comfortable, and effective.

Recordable haptic textures
IEEE transactions on haptics, 2013Co-Authors: A J Doxon, R J Woodham, Jeffrey Lloyd, Dinesh K. Pai, D. E. Johnson, William Ronald Provancher, H.-z. Tan, J. C. Lang, Domenico Prattichizzo, Francesco ChinelloAbstract:For designing a simple and more realistic haptic Feedback system, we propose integrating an underactuated mechanism with one-point Kinesthetic Feedback from the arm with multipoint tactile Feedback. By focusing on the division of roles between the cutaneous sensation in fingers and the proprioception in the arm. We have implemented a prototype system that provides Kinesthetic Feedback to the arm and tactile Feedback to the fingers, examined the difference of weight recognition according to the applied point of Kinesthetic Feedback, and confirmed the effectiveness of the proposed method.

using a fingertip tactile device to substitute Kinesthetic Feedback in haptic interaction
International Conference on Human Haptic Sensing and Touch Enabled Computer Applications, 2010Co-Authors: Domenico Prattichizzo, Kouta Minamizawa, Claudio Pacchierotti, Stefano Cenci, Giulio RosatiAbstract:A prototype of a joystick where the Kinesthetic Feedback is substituted by tactile Feedback is proposed. Tactile Feedback is provided by a wearable device able to apply vertical stress to the fingertip in contact with the joystick. To test the device, rigid wall rendering is considered. Preliminary experiments show that the sensation of touching a virtual wall using the force Feedback provided by the electric motor of the joystick is nearly indistinguishable from the sensation felt by the user using the tactile display only. The proposed device does not suffer from typical stability issues of teleoperation systems and is intrinsically safe.

EuroHaptics (2) - Virtual surface discrimination via an anisotropic-stiffness contact model
Haptics: Generating and Perceiving Tangible Sensations, 2010Co-Authors: Alessandro Formaglio, Gabriel Baud-bovy, Domenico PrattichizzoAbstract:In haptically enabled virtual reality, most existing devices render Kinesthetic Feedback via one 3DoF single-contact-point, thus they cannot stimulate tactily teh fingertip skin. This lack of information prevents the perception of contact surface orientation in absence of vision and of free exploratory movements. In this work we experimentally investigate the rendering performance of a contact model which exploits anisotropic contact stiffness to convey such information.
