No full textHaptic Desktop for Office Automation and Assisted Design
No full textThe present paper describes the conceptual and technical design of a new multimodal device named Haptic Desktop System (HDS). Haptic Desktop System is an integrated system, which merges haptic functionalities, and VDT systems into one. Specific care has been given to HDS design for enhancing and improving human-computer interaction from the following points of view: esthetical, ergonomic and functional. In order to improve the quality of the interaction, the HDS fully integrates proprioceptive, visual, audio and haptic functionalities, into a desk while minimizing the visual interference of the physical components. In the proposed approach classic input devices (i.e. keyboard and mouse) have been replaced by new features integrated within audio and haptic. Such features allow commanding and rendering natural force stimuli in such a way that they are completely coherent and co-located with respect to the visual information. The new features of the HDS are designed for reducing considerably the mental load required to the users during interaction operations. In the present paper the design guidelines and the achieved results are reported
Multisensorial Communication Method Between Services and Remote Users and System Architecture for Actuating It
No full textA communication method between one or more users ( 20 and 40 ) associated to respective workstations and one or more remote services ( 26 ) located in different geographic places connected by a communication network ( 21 ), capable of establishing a direct connection between a remote service agent ( 31 ) and an interface agent ( 28 and 43 ) in real time, creating a common immersive virtual environment to the users where said services are available and where said users ( 20 and 40 ) can cooperate in real time-According to this method, an user ( 20 ) comes into contact with a physic interface device ( 21 ), for example a haptic interface capable of transmitting to the user feedback signals making a virtual environment in which the user has the sensation to be immersed, connected to an interface agent ( 28 ) adapted to connect said physic interface device ( 21 ); with a connection network ( 27 ). The interface agent ( 23 ) is capable of analysing signals corresponding to the sensorial perception channels of the user, for example visual ( 28 ), haptic ( 29 ) and audio ( 30 ) channels. A second user ( 40 ), through a second haptic interface can connect to the same service ( 26 ) by an interface agent ( 43 ) entering in the same virtual environment of the first user ( 20 ), with which he can cooperate. The interface and service agents can generate local models ( 50 and 51 ) that are easily transmittable
Haptic desktop for assisted handwriting and drawing
No full textThis paper presents two applications developed for a novel multimodal device called haptic desktop system (HDS). The HDS is an integrated system which merges haptic functionalities and video display terminal (VBT) systems into one. It has been designed to provide visual and haptic co-located perceptual information. The first application is the integration of the HDS with a handwriting recognition system. In the second application, the interface can assist the users in a drawing task and act as a virtual guide through its force feedback capabilities; the application can read various image formats and convert the main image features in output control trajectories for user interaction
HERMES: An Angioplasty Surgery Simulator
No full textMinimally invasive surgery procedures are getting common in surgical practice; however this new interventional procedure requires a training process in order to be successful and safe. Computer-based simulators, with haptic feedback, can be an efficient method for facilitating the education and training process reducing costs of education and providing realism with regard to tissues behavior and real-time interaction. This work takes into account the results of the HERMES Project (hematology research virtual medical system). The aim of this project is to build an integrate system in order to simulate a coronary angioplasty intervention. The designed haptic interface is able to generate on the user a force and a torque in order to replicate on his fingertips the usual sensations perceived during a real angioplasty operation. The big axial run allows simulating all the operation without interruptions
The Haptic Desktop: a novel 2D multimodal device
No full textAs computing gets embedded into our everyday lives and moves from PCs to wide varieties of devices, we need new and flexible ways to interact with technology. Recently, the appearance of multimodal systems has been recognized to offer richer user experiences by combining different natural input modes, i.e., speech, touch, pen, hand gestures, etc.. in a coordinated manner with multimedia system outputs. As a new generation of multimodal systems begins to define itself, one dominant theme is the integration and synchronization requirements for combining different modes strategically into whole systems; where we can distinguish basically three modalities: visual, auditive, and tactile (physiology of senses). In order to provide a broader range of signal integrations, actually limited by the conventional input devices of computers, it becomes necessary to ensure that these interfaces interact in a manner akin to the way human interacts in real environments. Therefore, The design and integration of a novel multimodal device developed at PERCRO is described. This multimodal device, named Haptic Desktop, has been designed to replace the conventional input devices used for accessing the resources of computers. Furthermore, to assure the usability of the interface so that operators can extract efficiently the principal features of each perceptual channel from the device, the graphical visualization has been integrated to the haptic system on a single desktop to satisfy the coherence and co-location designing issues

Computer-Based Simulator for Catheter Insertion Training
No full textMinimally invasive surgery procedures are getting common in surgical practice; however the new interventional procedure requires different skills compared to the conventional surgical techniques. The need for training process is very important in order to successfully and safely execute a surgical procedure. Computer-based simulators, with appropriate tactile feedback device, can be an efficient method for facilitating the education and training process. In addition, virtual reality surgical simulators can reduce costs of education and provide realism with regard to tissues behaviour and real-time interaction. This work take into account the results of the HERMES Project (HEmatology Research virtual MEdical System), conceived and managed by Consorzio CETMA-Research Centre; the aim of this project is to build an integrate system in order to simulate a coronary angioplasty intervention
