Abstract: A system and method for providing customized content to a user is provided. The method includes: determining a plurality of learning objectives related to the course; assigning weights to the plurality of learning objectives; determining capability information for the user; determining a focus weight for each of the plurality of learning objectives for the user; and selecting content for the user based on the focus weight. The system includes: a learning objective engine configured to determine a plurality of learning objectives related to the course and assign weights to the plurality of learning objectives; a capability weight module configured to determine capability information for the user; a focus weight module configured to determine a focus weight for each of the plurality of learning objectives for the user; and a content amalgamation module configured to select content for the user based on the focus weight.

Abstract: A replaceable instrument mechanism for a haptic device comprises a coupler having a coupler body adapted to be connected to an output end of the haptic device. A force transmission mechanism is connected to the coupler body, has a movable connector displaceable along one degree-of-freedom with respect to the coupler body, and is connected to a force feedback system of the haptic device so as to receive force feedback from the haptic device and impart the force feedback to the movable connector. An instrument has an instrument body having a connector end releasably secured to the second end of the coupler body so as to be displaceable with the coupler. A handle portion is manually actuatable in one degree-of-freedom with respect to the instrument body to simulate an operation performed with the instrument.
