Abstract

A training apparatus presents a virtual environment to a user and allows the user to interact with the virtual environment. The training apparatus includes a base, an interface and a tool. The base has a storage device and a central processing unit. The interface may provide haptic feedback responsive to interaction between the user and the virtual environment. The tool is operatively coupled to the interface, by which the user interacts with the virtual environment, and through which haptic feedback may be provided to the user from the interface. The tool has storage for software code that forms an application defining the virtual environment.

5. A training apparatus as set forth in claim 1, wherein the tool includes storage for driver information executable by the processing unit to allow the processing unit to recognize the tool upon connection with the interface.

6. A training apparatus as set forth in claim 5, wherein the tool is operable to automatically download and install the driver information to the storage device of the base so that the processing unit recognizes the tool upon connection of the tool with the interface.

7. A training apparatus as set forth in claim 1, wherein the interface provides haptic feedback to the user in response to interaction between the user and the virtual environment.

8. A medical training apparatus for allowing a user to interact with a virtual environment, the training apparatus comprising:

a base having a storage device and a central processing unit;

an interface operatively coupled to the base and the tool to allow interaction between the user and the virtual environment; and

a plurality of tools each simulating a different instrument used in a medical setting, each of the plurality of tools being releasably connectable to the interface so as to operatively couple the tool to the base thru the interface, each of the tools having storage for a unique software code that forms an application defining the virtual environment in a manner specific to each of the plurality of tools.

9. A medical training apparatus as set forth in claim 8, wherein the interface if further operative to provide haptic feedback to the user in response to interaction between the user and the virtual environment.

10. A medical training apparatus as set forth in claim 9, wherein the tools are releasably connectable to the interface by a standardized male and female arrangement providing both a mechanical connection allowing the haptic feedback to be provided between the interface and the user via the tool and a data connection allowing data sharing between the tools, the interface and the base.

11. A training apparatus as set forth in claim 8, wherein each of the plurality of tools is operable for automatically downloading at least part of the software code to the storage device of the base upon connection of each of the plurality of tools to the interface.

12. A training apparatus as set forth in claim 8, wherein each of the plurality of tools is operable to automatically download and launch a set of instructions directing the processing unit to execute the application upon connection of each of the plurality of tools to the interface.

13. A method of training comprising the steps of:
