Abstract
A grip member is equipped with a plurality of modules for generating haptic feed-back distributed along the grip member and activatable according to a pre-set sequence.
Claims19
A grip member comprising means for generating a haptic feed-back, wherein said means comprise a plurality of haptic feed-back generator modules distributed along said grip member, and means for controlling activation of said modules according to a pre-set sequence in such a way as to generated a pre-set haptic signal on said grip member,
- wherein the pre-set haptic signal is of a type travelling along the grip member, in such a way as to transmit a sensation of direction,
- wherein each module has a body of a substantially cylindrical shape with two opposite faces set on which is a piezoelectric element constrained in at least one point to the body so that the mechanical vibration of the piezoelectric element is transmitted to the module itself, and
- wherein the piezoelectric element is equipped with a striking member co-operating with the body so that a pulsed electrical supply of the piezoelectric element causes an alternating percussion of the striking member against the body of the module such as to impart a vibratory effect upon said body.
A grip member comprising means for generating a haptic feed-back, wherein said means comprise a plurality of hapic feed-back generator modules distributed along said grip member, and means for controlling activation of said modules according to a pre-set sequence in such a way as to generate a pre-set haptic signal on said grip member,
- wherein each of said modules comprises a piezoelectric element designed to generate a haptic signal of vibratory type,
- wherin said body is provided with elements for damping the vibrations that isolate the vibrations generated thereon with respect to the adjacent modules and with respect to the corresponding supporting structure, and
- wherein said damping elements comprise two plates made of material for damping the vibrations, which coat the opposite faces of the body and two tubes made of damping material arranged within two through holes made in the body and traversed by two supporting rods of the set of modules.
