First Claim
1. A device, comprising:
- a housing;
an actuator coupled to said housing, the actuator configured to receive a control signal, the control signal based on data values associated with at least one of an event associated with an external environment and a function of an external apparatus, the actuator configured to produce an inertial force based on the control signal, the inertial force having a first component associated with a frequency range and a second component associated with a frequency range different from the frequency range of the first component; and
a compliant suspension coupled to said actuator and said housing, said compliant suspension member having a compliance such that said compliant suspension is configured to magnify the first component of the inertial force, the compliant suspension configured to impart the magnified inertial force including the magnified first component of the inertial force to the housing.

Abstract
Method and apparatus for increasing the transmissibility of inertial forces produced by an inertial actuator on the housing of a tactile feedback interface device. A tactile interface device, coupled to a host computer, outputs tactile sensations to a user based on interactions and events occurring in a displayed graphical environment. An actuator produces periodic inertial forces, such as vibrations, and a compliant suspension couples the actuator to the device housing. A compliance of the suspension is selected such that the suspension magnifies the periodic inertial forces for a particular frequency range of the inertial forces. The magnified inertial forces are transmitted to the housing to be felt by the user.
