Abstract: A physical interaction device includes a controller and one or more arms, such as a first arm and a second arm. The first arm is movably connected with a first support. The first arm includes a first flexible portion sized to physically interact with a first limb portion of a user of the device. The second arm is movably connected with a second support. The second arm includes a second flexible portion sized to physically interact with the first limb portion of the user and/or a second limb portion of the user. The controller is linkable with the first arm and the second arm. The controller is configured to selectively cause a first movement of the first flexible portion of the first arm. The controller is configured to selectively cause a second movement of the second flexible portion of the second arm. The first movement of the first flexible portion of the first arm serves to contact the first flexible portion of the first arm with the user to physically imitate a first human strike toward the user.
