Patent number: 8456418Abstract: An apparatus for detecting a pointer within a region of interest includes a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. A second reflective element extends along a second side of the region of interest and reflects light towards the region of interest. The second side is joined to the first side to define a first corner. A non-reflective region generally in the plane of at least one of the first and second reflective elements is adjacent the first corner. At least one imaging device captures images of the region of interest including reflections from the first and second reflective elements.Type: GrantFiled: June 13, 2007Date of Patent: June 4, 2013Assignee: SMART Technologies ULCInventors: Chi Man Charles Ung, David Kenneth Booth, Stephen Worthington, Mark Andrew Fletcher, Roberto A. L. Sirotich

Publication number: 20120274765Abstract: An apparatus for detecting a pointer within a region of interest comprises a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. The first reflective element comprises at least two generally parallel bands thereon, the bands at least comprising a retro-reflective band and a reflective band. A second reflective element extends along a second side of the region of interest and reflects light towards the region of interest, the second side being joined to the first side to define a first corner. The second reflecting element comprises at least two generally parallel bands thereon, the bands at least comprising a retro-reflective band and a reflective band. At least one imaging device captures images of the region of interest including reflections from the reflective and retro-reflective bands of the first and second reflective elements.Type: ApplicationFiled: February 28, 2012Publication date: November 1, 2012Applicant: SMART TECHNOLOGIES ULCInventors: Chi Man Charles Ung, David Kenneth Booth, Stephen Worthington, Roberto A.L.

Patent number: 8274496Abstract: An apparatus for detecting a pointer includes a waveguide and a touch surface over the waveguide on which pointer contacts are to be made. At least one reflecting device extends along a first side of the waveguide and touch surface. The reflecting device defines an optical path between the interior of the waveguide and the region of interest above the touch surface. At least one imaging device looks across the touch surface and into the waveguide. The imaging device captures images of the region of interest and within the waveguide including reflections from the reflecting device.Type: GrantFiled: October 31, 2008Date of Patent: September 25, 2012Assignee: SMART Technologies ULCInventors: Chi Man Charles Ung, David Kenneth Booth, Roberto A. L. Sirotich

Publication number: 20100079385Abstract: A method of calibrating an interactive input system comprises receiving images of a calibration video presented on a touch panel of the interactive input system. A calibration image is created based on the received images, and features are located in the calibration image. A transformation between the touch panel and the received images is determined based on the located features and corresponding features in the calibration video.Type: ApplicationFiled: September 29, 2008Publication date: April 1, 2010Applicant: SMART TECHNOLOGIES ULCInventors: DAVID E. HOLMGREN, George Clarke, Roberto A.L. Sirotich, Edward Tse, Yunqui Rachel Wang, Joe Wright, Grant McGibney

Publication number: 20100079409Abstract: A touch panel for an interactive input system and interactive input system incorporating the touch panel is provided. The touch panel includes an optical waveguide layer and a resilient diffusion layer. The resilient diffusion layer is against the optical waveguide layer and causes light traveling within the optical waveguide layer to escape only when compressed against the optical waveguide layer at one or more touch points.Type: ApplicationFiled: September 29, 2008Publication date: April 1, 2010Applicant: SMART TECHNOLOGIES ULCInventors: Roberto A.L.
