Interactive learning desk with document camera

Abstract

The present invention provides a smart, electronic desk to facilitate and improve interactive learning. The desk comprises a student desk having a table, a computer such as a tablet having a touch-screen interface, and a document camera all integrated together. The interface displays electronic information to the student and provides a graphic user interface that allows the student to interact with programs or apps through graphical icons and visual indicators. The document camera, also known as a visual presenter, captures images and/or video of documents or other objects placed on the table. The computer comprises a bilateral communications interface to communicate information such as, but not limited to video, between the computer and optional document camera at the electronic desk, and any number of other computers.

DETAILED DESCRIPTION OF EMBODIMENTS

(8) Further features and advantages of the invention, as well as the structure and operation of various embodiments of the invention, are described in detail below with reference to the accompanying FIGS. 1-6, wherein like reference numerals refer to like elements. Although the invention is described in the context of classroom furniture (e.g., a student desk), the present invention can be utilized as any type of furniture including, but not limited to office or home furniture.

(9) FIG. 1 illustrates a classroom desk 100 according to an embodiment of the invention. The desk 100 comprises a computer 110, a table (i.e., writing surface) 120, a document camera 125 (shown in a lowered position underneath the table 120 and partially hidden from view), and a chair 130 integrated together as a single piece of furniture. The computer 110 is permanently secured to the table 120 via a mounting structure (not shown). Alternatively, the computer 110 can be detachably coupled to the table 120 so that the student may take the computer 110 away from the desk 100. In a preferred embodiment of the invention, the computer 110 is a tablet computer with a touchscreen interface with an operating system such as Apple iOS, Microsoft Windows, or Google Android, among others, the implementation of which are readily apparent to one of ordinary skill in the art. FIG. 1 shows the computer 110 in a closed position. In this position, the surface of the computer 110, e.g., touchscreen interface, is integrated into and may be flush with the table 120 to provide the student with a writing surface. For example, the top side of the computer 110 may have a protective covering to allow the student to place objects and writing materials on the computer 110 without damaging it.

(10) The table 120 and chair 130 may take any form factor whether combined together as shown or as separate pieces of furniture. In a preferred embodiment of the invention, the table 120 and chair 130 are integrated into a single piece of classroom furniture; for example, a table arm desk as shown. Alternatively, the table 120 and chair 130 can be unconnected pieces of disparate furniture. For example, the table 120 can be a stand-up desk, open front desk, office desk, a multi-student desk or group learning desk (with multiple computers 110), a lift lid desk (where the computer 110 is in the lid), or other type of workstation. Any type of appropriate chair 130 can then be used with such a standalone table 120.

(11) In an embodiment of the invention, the document camera 125 can magnify and project the video image of documents and three-dimensional objects placed on the writing surface 120. In an exemplary embodiment of the invention, the document camera 125 comprises optics, camera, an optional lighting system, and a motherboard with appropriate firmware. Simple or highly complex optical system can be used. The camera preferably a progressive scan camera, e.g., a charge-coupled device (CCD) sensor or complementary metal-oxide semiconductor (CMOS) sensor, to provide high-resolution color images at thirty (30) frames per second or more. A lighting system may be used to illuminate the writing surface. The motherboard may have a variety of connections to output video such as HDMI, DVI, VGA, USB, and/or LAN, the implementation of which are apparent to one of ordinary skill in the art. The document camera 125 may also be equipped with wireless technology such as, but not limited to WIFI to eliminate the need for cables. The term document camera as used herein means a device as noted above that can direct its camera toward the writing surface, preferably from vertically overhead the writing surface.

(12) FIG. 2 illustrates the student desk 100 with the computer 110 in an open position. The computer 110 can be a tablet computer having a touchscreen display 112. In an optional embodiment of the invention, the computer 110 comprises a keyboard 114. As shown in the left figure, the bottom/underneath of the keyboard 114 faces upward when at or near a closed position. The bottom of the keyboard 114 is preferably flush with the table 120 when closed to provide a smooth writing surface. As shown in the right figure, the top of the keyboard 114, i.e., the surface with the keys, faces upward when in the open (expanded) position. An optional bumper or wrist rest 116 can be provided as shown.

(13) FIG. 3 illustrates rotation of the computer 110 about a vertical axis and horizontal axis. A hinge 310 comprising two or more pivots is employed to facilitate rotation about the horizontal and vertical axes.

(14) In an embodiment of the invention, the document camera 125 can rotate about a hinge 127 fastened to a side of the table 120 among a lowered position (under the table 120 as shown in FIG. 1) and the upright position (as shown in FIG. 3), or any position there between. For example, imaging devices with an adjustable arm (with one or two pivot points) such as those disclosed in U.S. Pat. Nos. D715,300 and D677,707 can be modified to attach to the table 120.

(15) FIG. 4 illustrates the touchscreen display 112 it tilted positions. As shown at top, the display can be tilted away from the chair 130 in order for the document camera 125 to be rotated in its raised (i.e., open) position. As shown in the bottom figures, the display 112 can be rotated in a position where it faces upward when the computer is in a closed position. Here, a student can use the touchscreen display 112 as a multi-touch surface even when the computer is in the closed position. In an embodiment of the invention, the table 120 may include a recess portion (not shown) so that the display is flush with the surface of the table 120.

(16) FIG. 5 illustrates a close-up of the document camera 125 when in its lowered position below the table 120. Here, a clip 129 may be provided to lock the document camera 125 in its lowered position and out of the way of the student.

(17) FIG. 6 illustrates a student desk and floor system 600 according to an embodiment of the invention. The system comprises the student desk 100, a conduit 610 for wires, and a plurality of floor tiles 620. The conduit 510 houses unsightly wires such as a power cable or communications cable, and can be integrated into the student desk 100 to form a single piece of furniture. The floor tiles 620 comprise spacers (not shown) between the floor and tile to allow for such cables to be hidden for visual purposes and to avoid people and objects from coming in contact with the cables. One or more floor tiles 620 may include an opening 622 for receiving the conduit 610.

(18) In an embodiment of the invention, the computer 110 (along with the document camera 125) communicates with a teacher's computer or other student computers wirelessly, for example, via IEEE 802 protocol, Bluetooth, or ZigBee. The document camera 125 can acquire video via the computer 110 as described in U.S. Pat. No. 8,508,751, the entire disclosure of which is incorporated by reference herein. The computer 110 provides a platform for interactive learning applications (or apps) to run. These apps may include, but are not limited to: digital text books, a classroom response system, test facilitators, social networking apps, email, homework submission apps, productivity apps, and cloud server apps (for enabling, for example, online storage, bookmarking in text books, etc.).

(19) The invention has been described herein using specific embodiments for the purposes of illustration only. It will be readily apparent to one of ordinary skill in the art, however, that the principles of the invention can be embodied in other ways. Therefore, the invention should not be regarded as being limited in scope to the specific embodiments disclosed herein, but instead as being fully commensurate in scope with the following claims.
