Abstract:
A haptic device (100) configured to be used as man-machine interface for interactions in virtual and/or real places, tele-operation and rehabilitation assisted by robot comprises a mobile unit (1) configured to be interfaced with at least one user (3), a control unit (4) associated with the mobile unit (1 ) and a feeding unit (10). In particular, the mobile unit (1 ) comprises at least three wheels (13) rotationally spaced from each other; each wheels (13) comprises a rotation axis (13') and has a wheel motor unit (1 1) independent, such that each wheel motor unit (1 1) allows the rotation of each wheel (13) about the respective rotation axis (13') in a rotation plane orthogonal to the rotation axis (13'). In addition, each wheel (13) has sliding means (21 ) in a direction transversal to the rotation support plane, such that the mobile unit (1 ) can follow any trajectory. In particular, the sliding means comprises a plurality of rollers (21) arranged adjacent to each other on a same row. This way, each wheel (13) can carry out a "leeway motion" transversally to each wheel rotation plane by the resulting rolling applied by the respective motor units (1 1 ) to the other wheels (13). In particular, in case of three wheels (13) of the mobile unit (1), if a first wheel it has not momentarily a rolling movement, giving to the other two wheels (13) an identical rolling speed, is obtained a translating the first wheel orthogonally to each wheel rotation plane i.e. parallel to its own rotation axis (13'). Giving instead different speeds to the other two wheels (13), it is possible to obtain a movement in a direction oblique with respect to the rotation plane of the first wheel.

Abstract:
A 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.
