Entertainment device and method of interaction

1. A method of interaction for an augmented reality environment, comprising the steps of:

capturing an image of a drawn picture comprising a plurality of drawn shapes;

identifying an archetypal model corresponding to said drawn picture and identifying respective components of said archetypal model corresponding to respective drawn shapes of the plurality of drawn shapes in said drawn picture; and

generating a three dimensional virtual model from said respective drawn shapes corresponding to respective components of said identified archetypal model using generation rules associated with said identified archetypal model, wherein components of the three dimensional virtual model corresponding to respective components of said identified archetypal model have the shape of the respective corresponding drawn shape.

2. A method according to claim 1 , in which said generation rules associated with said identified archetypal model include that a component corresponding to a shape from the image of the drawing corresponding in turn to a predetermined component of the identified archetypal model is duplicated and offset in the third dimension to produce two separate components of the three dimensional virtual model corresponding to the same respective drawn shape.

3. A method according to claim 1 , in which said generation rules associated with the identified archetypal model include one or more selected from the list consisting of:

i. that different shapes corresponding to different components of the archetypal model are extruded into the third dimension by differing extents;

ii. that a shape from the image of the drawing corresponding to a predetermined component of the archetypal model is used to generate a solid of rotation; and

iii. that a shape from the image of the drawing corresponding to a predetermined component of the archetypal model is rotated into a plane orthogonal to the plane originally occupied by the shape.

4. A method according to claim 1 , in which the resulting three dimensional virtual model is combined with a captured video feed to form an augmented reality environment.

5. A method according to claim 1 , in which the resulting three dimensional virtual model is controllable by a user.

6. A method according to claim 1 , in which the resulting three dimensional virtual model interacts with a computer controlled avatar.

7. A method according to claim 6 , in which the three dimensional virtual model interacts in a manner dependent upon the archetypal model to which the three dimensional virtual model corresponds.

8. A non-transitory computer-readable storage medium on which computer readable instructions of a program are stored, the instructions, when executed by a processor, cause the processor to perform a method of interaction for an augmented reality environment, the method comprising:

capturing an image of a drawn picture comprising a plurality of drawn shapes;

identifying an archetypal model corresponding to said drawn picture and identifying respective components of said archetypal model corresponding to respective drawn shapes of the plurality of drawn shapes in said drawn picture; and

generating a three dimensional virtual model from said respective drawn shapes corresponding to respective components of said identified archetypal model using generation rules associated with said identified archetypal model, wherein components of the three dimensional virtual model corresponding to respective components of said identified archetypal model have the shape of the respective corresponding drawn shape.

9. An entertainment device, comprising:

a video input operable to receive video data;

an image capturer operable to capture an image of a drawn picture comprising a plurality of shapes from said video data;

a shape identifier operable to identify an archetypal model corresponding to said drawn picture and identifying respective components of the identified archetypal model corresponding to respective drawn shapes of the plurality of drawn shapes in said drawn picture; and

a three dimensional modeller operable to generate a three dimensional virtual model from said respective drawn shapes corresponding to respective components of said identified archetypal model using generation rules associated with said identified archetypal model, wherein components of said three dimensional virtual model corresponding to components of said identified archetypal model have the shape of said respective corresponding drawn shape.

10. An entertainment device according to claim 9 , in which said generation rules associated with said identified archetypal model include that a component corresponding to a shape from said image of the drawing corresponding to a predetermined component of said identified archetypal model is duplicated and offset in the third dimension to produce two separate components of said three dimensional virtual model corresponding to the same respective drawn shape.

11. An entertainment device according to claim 9 , in which said generation rules associated with the archetypal model include one or more selected from the list consisting of:

i. that different shapes corresponding to different components of the archetypal model are extruded into the third dimension by differing extents;

ii. that a shape from the image of the drawing corresponding to a predetermined component of the archetypal model is used to generate a solid of rotation; and

iii. that a shape from the image of the drawing corresponding to a predetermined component of the archetypal model is rotated into a plane orthogonal to the plane originally occupied by the shape.

12. An entertainment device according to claim 9 , in which the resulting three dimensional virtual model is combined with a captured video feed to form an augmented reality environment.

13. An entertainment device according to claim 9 , in which the resulting three dimensional virtual model is controllable by a user.

14. An entertainment device according to claim 9 , in which the resulting three dimensional virtual model interacts with a computer controlled avatar.

15. An entertainment device according to claim 14 , in which the mode of interaction is dependent upon said identified archetypal model to which said three dimensional virtual model corresponds.
