Abstract
A Tactile-Visual Wound (TVW) simulation unit is a physical device designed to help simulate a wound on a human being or human surrogate (e.g., a medical manikin) for instructing a trainee to learn or practice wound-related treatment skills. For the trainee, the TVW would feel (to the touch) like a real wound, look like a real wound when viewed using an Augmented Reality (AR) system, and appear to behave like a real wound when manipulated.
Claims20
A tactile, augmented reality wound simulation system comprising:
- a corporeal object deformable by physical manipulation simulating the tactile and dimensional features of a wound on a body surface initially in a first state;
- a visual graphic enhancement of the simulated wound, renderable via an augmented reality mechanism selected from the group consisting of video see-through headsets, optical see-through headsets, handheld augmented reality devices, and spatial augmented reality devices;
- whereby the visual graphic enhancement overlays the wound visually on the corporeal object via the augmented reality mechanism;
- one or more reference indicia detectable by an optical sensor, the indicia fixed to the surface of the corporeal object;
- and
- a computer processor communicatively coupled to the optical sensor and the augmented reality display, the computer processor executing a software process using the indicia on the corporeal object to dynamically locate, size, orient, and warp the visual graphic enhancement rendering of the wound simulated on the corporeal object whereby changes to the indicia positions or indicia orientations caused by physical manipulation of the corporeal object to a second state invoke the software process to reconstruct spatial and dimensional parameters of the visual graphic enhancement so that there is a synchronization of the augmented reality rendering to the second state of the corporeal object.

A manikin for medical training simulation, the manikin comprising:
- one or more reference indicia on the manikin detectable by an optical sensor, the indicia fixed to the surface of the manikin wherein the reference indicia orients, dimensions, and warps a visual graphic enhancement of a simulated wound via an augmented reality mechanism selected from the group consisting of one or more of video see-through headsets, optical see-through headsets, handheld augmented reality devices, and spatial augmented reality devices;
- the mechanism further coupled to a computer simulation engine;
- one or more sensors affixed on or in the manikin, the sensors detecting a value selected from the group consisting of object proximity;
- mechanical pressure;
- temperature;
- sound;
- articulation;
- and light;
- a computer-controlled physical response component integrated to the manikin, the response selected from the group consisting of movement, sound, and fluid flow;
- a first communications interface coupling the sensor to the computer simulation engine;
- and
- a second communications interface coupling the physical response component to the computer simulation engine whereby responsive to receiving sensor data, the computer simulation engine automatically changes the state of the response component and visual graphic enhancement of the simulated wound.

A wound simulation system comprising:
- a physical object simulating the tactile and dimensional features of a simulated wound on a body surface;
- one or more reference indicia detectable by an optical sensor, the indicia fixed to the surface of the physical object;
- a computer processor communicatively coupled to the optical sensor and an augmented reality headset, the computer processor executing a software process using the indicia on the physical object to orient, dimension, and warp a visual graphic enhancement of the simulated wound for display on the headset, the tactile features, dimensional features and visual graphic enhancement of the simulated wound forming a first state of the wound simulation system;
- and
- a sensor on the physical object configured to detect action by the user with respect to the physical object, the sensor communicatively coupled to the computer processor wherein responsive to action detected by the sensor the computer processor modifies the wound simulation system to a second state.
