Abstract
One aspect of the invention involves a writing tablet comprising a housing having a writing surface and internal logic placed within the housing and situated below the writing surface. The internal logic includes imaging sensor, a light source and a controller. The imaging sensor is adapted to capture a location and orientation of each line segment forming a graphic image. The light source is adapted to produce a light beam adjusted for display on the writing surface. The controller is adapted to control performance of an event upon the light beam crossing a line segment of the graphic image.
Claims12
A writing tablet comprising:
- a housing including a wilting area;
- and
- logic contained within the housing and situated below the writing area, the logic including
- an imaging sensor to detect a graphic image on the writing area,
- a light source to produce on a back surface of the writing area facing an interior of the housing a light beam that is adjusted for display on the writing area,
- a speaker,
- an internal memory, and
- a controller coupled to at least the internal memory, the light source, the imaging sensor and the speaker, the controller to control generation of an audible rendition of an alphanumeric character for output from the speaker in response to both the light beam crossing a line segment of the graphic image previously captured by the imaging sensor and the controller identifying the graphic image as the alphanumeric character.
A method comprising:
- detecting placement of a graphic image on a writing area of a writing tablet;
- generating light beam on a back surface of and visible through the writing area to represent an area of the writing tablet being analyzed and adjusted to move over the graphic image;
- and
- triggering at least one of an audible effect and a visual effect in response to the light beam intersecting a line segment of the graphic image previously drawn on and currently displayed within the writing area and recognition that the graphic image as a particular alphanumeric character, the audible effect being an audible rendition of the alphanumeric character.
