Interface apparatus
View Patent ↗In an interface apparatus for presenting a force sense at a remote place or in a virtual space to a user, the number of motors for exerting force upon fingers of the user is decreased. The interface apparatus includes a first arm and a second arm for being attached to the thumb and a finger other than the thumb, respectively. A motor includes a motor main body supported for rotation, and a rotary shaft that relatively rotates with respect to the motor main body. The rotary shaft is connected to the second arm. The motor main body is connected to the first arm so as to impart rotation thereof to the first arm.
1. An interface apparatus comprising:
a first arm and a second arm mounted for opening and closing motion being attached to a thumb and a finger other than the thumb, respectively; and
a motor configured to exert force in opening and closing directions on the first arm and the second arm and include a motor main body supported to be rotatable and a rotary shaft that relatively rotates with respect to the motor main body, the rotary shaft being connected to one of the first arm and the second arm while an other one of the first and second arms and the motor main body are connected to each other so as to impart rotation of the motor main body to the other one of the arms;
wherein the first arm is rotatable around a first axis; and
the second arm is rotatable around a second axis positioned in a spaced relationship from the first axis.
2. An interface apparatus comprising:
a first arm and a second arm mounted for opening and closing motion being attached to a thumb and a finger other than the thumb, respectively; and
a motor configured to exert force in opening and closing directions on the first arm and the second arm and include a motor main body supported to be rotatable and a rotary shaft that relatively rotates with respect to the motor main body, the rotary shaft being connected to one of the first arm and the second arm while another one of the first and second arms and the motor main body are connected to each other so as to impart rotation of the motor main body to the other one of the arms; a first arm and a second arm mounted for opening and closing motion being attached to a thumb and a finger other than the thumb, respectively; and
a motor configured to exert force in opening and closing directions on the first arm and the second arm and include a motor main body supported to be rotatable and a rotary shaft that relatively rotates with respect to the motor main body, the rotary shaft being connected to one of the first arm and the second arm while an other one of the first and second arms and the motor main body are connected to each other so as to impart rotation of the motor main body to the other one of the arms;
wherein the motor is disposed in a posture in which the rotary shaft extends orthogonally to a plane on which the first arm and the second arm open or close.
3. The interface apparatus according to claim 2 ,
wherein the motor is disposed between the first arm and the second arm.
4. The interface apparatus according to claim 3 , further comprising:
a motor case configured to accommodate the motor main body therein and support the motor main body for rotation; and
a member positioned in a spaced relationship in a radial direction from the motor case and cooperating with the motor case to sandwich a hand of the user therebetween.
