US10664070's Independent Claims (Summarized):

  • Claim 1 (Interactive device): A stylus emitting electromagnetic radiation; a display screen (touch-sensitive) with selectable icons; a sensor array (sensitive layer proximate to the display) detecting the beam; and a processing unit determining the stylus's three-dimensional (3D) position based on the beam's distribution pattern, linking this 3D position to a selectable icon, determining a selection function, and executing a related function.
  • Claim 10 (Interactive system): Similar to Claim 1, but framed as a system.
  • Claim 16 (Method): A method comprising steps mirroring the features of Claims 1 and 10, including emitting, displaying, detecting, determining 3D position based on distribution, associating with an icon, determining a selection function, and executing.

Key features for anticipation analysis include:

  • Stylus emitting electromagnetic radiation (e.g., conical beam).
  • Detection of this radiation by a sensor array proximate to a display.
  • Determination of 3D position (X, Y, Z, and/or angle) from the radiation's distribution pattern (e.g., area, intensity, elliptical eccentricity).
  • Use of this 3D position for non-contact interaction, particularly selection functions like zoom.

Most Relevant Prior Art (Published Before 2002-06-08)

Based on the titles and available descriptions, the most relevant prior art documents that potentially anticipate claims of US10664070 under 35 U.S.C. § 102, due to their focus on 3D input or optical/non-contact stylus interaction, are:

  • US5227985A (Published: 1993-07-13): "Computer vision system for position monitoring in three dimensions using non-coplanar light sources attached to a monitored object." This patent is highly relevant as it explicitly discloses a system for "position monitoring in three dimensions" using "light sources attached to a monitored object" (analogous to a stylus emitting electromagnetic radiation). This directly anticipates the "determining a three-dimensional position of the stylus relative to the interactive device based on the distribution pattern" of Claims 1, 10, and 16.

  • JPH05265637A (Published: 1993-10-15): "Three-dimensional pointing device." This patent directly discloses a "three-dimensional pointing device," which anticipates the core functionality of US10664070's stylus as an input means for 3D control.

  • US5892501A (Published: 1999-04-06): "Three dimensional wireless pointing device." Similar to the Japanese patent, this explicitly describes a "three-dimensional wireless pointing device," strongly anticipating the 3D position determination and input means of US10664070. "Wireless" suggests non-contact operation, further aligning with US10664070.

  • US6081255A (Published: 2000-06-27): "Position detection apparatus and remote control apparatus." This patent, notably cited by the examiner, indicates a focus on non-contact "position detection" for a "remote control apparatus." If this "remote control" is a stylus-like device utilizing electromagnetic radiation for 3D position sensing to control a display, it would be highly anticipatory of Claims 1, 10, and 16.

  • US5926168A (Published: 1999-07-20): "Remote pointers for interactive televisions." Also cited by the examiner, this patent describes "remote pointers" for interaction with a display, suggesting non-contact control. If these pointers include 3D sensing mechanisms relevant to US10664070, they would be anticipatory of the input means and control functions.

While other patents anticipate certain isolated elements (e.g., touch-sensitive displays, light pens for 2D, general input devices), these five patents appear to be the most directly relevant as they touch upon the combination of 3D position determination and/or non-contact pointing, which are central to the innovation claimed in US10664070.
