The system consists of a CAD (Computer Aided Design) system enhanced with intuitive designer-oriented interaction tools and modalities. The system integrates innovative 6 degrees of freedom haptic tools for modeling digital shapes, with sweep operators applied to class-A surfaces and force computation models based on chip formation models. The ...

During this activity experts in different phases of the production process (eg design, manufacturing, handling, etc.) cooperate to propose, evaluate and adapt, in a stepwise manner, the model to the working environment requirements. This cooperative methodology is general in that it was proved in different fields from aerospatial, to electronic, to ...

The device haptically renders curves belonging to digital surfaces. The device is a haptic strip consisting of a modular servo-controlled mechanism able to deform itself, allowing the user to feel the resulting shape with his free hands. The haptic strip is also equipped with two force sensitive handles placed at the extremities, and a capacitive touch sensor along its length, which are used for applying deformations to the digital shape.

The framework manages the exchange of data within the clients of a system and permits the definition of a specific behavior for each client using a finite-state machine approach. Whilst the server-side of the framework is able to receive and dispatch events and data, the client-side of the framework is modeled as a finite-state machine able to perform state transitions ...

Some preliminary tests conducted with industrial designers have showed that the trajectories performed while exploring the surface of a style product, for a qualitative evaluation, follows some particular trajectories that may be mathematically described as geodesic curves. In order to represent these particular curves a haptic strip based on a ...

The haptic sensation is created by tilting one or more rotating flywheels along an axis, controlling the direction and the amount of tilt, the velocity of the tilt (during the pulse and the repositioning of the flywheel), the frequency of pulses. The current prototype has only one flywheel and is able to tilt along a single axis, ...

Such a device allows a continuous, free hand contact on a developable plastic tape actuated by a modular servo-controlled mechanism using the tessellation approach. The device has enabled users to interact with and feel a wide variety of virtual objects by using the palm of the hand. This research work discusses the design concept, novel kinematics and mechanics of the Desktop Strip.

In particular, Augmented Reality (AR) technologies include tracking systems, stereoscopic visualization systems, photorealistic rendering tools, hi-resolution video overlay systems that allow us to create various types of applications where the virtual prototype is contextualized within the real world. One application domain is product design: AR technologies allow designers to perform some evaluation tests on the virtual prototype of industrial products without the necessity to produce a physical prototype. This paper describes the development of a new Video See-Through Head Mounted Display (VST-HMD) that is high-performing and based on stereoscopic visualization. The developed display system overcomes some issues concerning the correct visualization of virtual objects that are close to the user’s point of view. The paper also presents the results of some tests about an AR application developed for product design assessment.

This practice can be effectively used for rapid design assessment of new products. In particular, the paper addresses applications regarding the use of mixed prototyping practice for the design review of information appliances. Various methods and technologies can be used according to the product aspects to validate and test. The paper describes mixed prototyping applications for positioning information appliances within systems and for the evaluation of ergonomics aspects of interactive devices.
