TLDR
In this paper, the authors propose a sensing device for: sensing coded data disposed on a surface; and generating interaction data based on the sensed coded data, the interaction data being indicative of interaction of the sensing device with the surface; the device comprising an image sensor for capturing image information; at least one analog to digital converter for converting the captured image information into image data; an image processor for processing the image data to generate processed image data.Abstract:
A sensing device for: sensing coded data disposed on a surface; and generating interaction data based on the sensed coded data, the interaction data being indicative of interaction of the sensing device with the surface; the sensing device comprising: (a) an image sensor for capturing image information; (b) at least one analog to digital converter for converting the captured image information into image data; (c) an image processor for processing the image data to generate processed image data; (d) a host processor for generating the interaction data based at least partially on the processed image data.read more

Patent
Absolute optical position determination
TL;DR: In this article, the authors proposed the use of a data surface (e.g., paper) formatted with a position-related coding (figure 1a) for indicating X-Y coordinates capable of reflecting a frequency of light.
Patent
Optical position determination
TL;DR: In this article, a coordinate sensor is proposed for detecting the position of a moveable detector relative to a data space coded with coordinate information by detecting and processing the coordinate information. But this sensor is not suitable for the detection of human motion.
Patent
Pen and paper information recording system
TL;DR: In this paper, an information recording system includes a writing paper having a writing surface and a prerecorded invisible pattern of pixels associated with the writing surface, each of the pixels contains encoded, optically readable position information which identifies a coordinate position on the writing surfaces.
