Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to interactive education and more specifically, to a smart, electronic desk including a document camera.

2. Description of Related Art

Passive learning involves students listening to teachers lecture or memorization of information. At times, passive learning has its place as students need to memorize pertinent facts and figures. However, sitting at a desk copying figures from a chalkboard or whiteboard does not often play into the strengths of students.

Today's students are growing up in a technology-rich environment. Schools are turning to interactive learning to inspire students and bolster teacher-student relationships. In interactive learning, students participate in the lesson plan through technology, e.g., online reading or math software. Interactive learning sharpens critical thinking skills, which are fundamental to the development of analytic reasoning. A student who can explore an open-ended question with imagination and logic is learning how to make decisions, as opposed to just regurgitating memorized information. Also, interactive learning teaches students how to collaborate and work successfully in groups, an indispensable skill as workplaces become more team-based in structure.

SUMMARY OF THE INVENTION

The present invention provides a smart, electronic desk to facilitate and improve interactive learning. The desk comprises a student desk having a seat and table (i.e., writing surface), a computer such as a tablet having a touch-screen interface integrated into the writing surface, and a document camera integrated into the desk. 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 touch-screen monitor may optionally include a video camera in addition to the document camera. 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/or document camera) at the electronic desk and any number of other computers, e.g., other electronic desks, a teacher's computer, or a classroom monitor.

In an embodiment of the invention, a desk comprises: a writing surface; a touchscreen interface of a computer integrated into the writing surface; and a document camera, wherein the document camera is structurally configured to move between a lowered position to an upright position. The lowered position is below the writing surface. The upright position is above the writing surface and a camera of the document camera is downwardly facing the writing surface. The touchscreen interface is detachably coupled to the writing surface. The computer is a tablet. An edge of the tablet is configured to act as a pivot in order to move the tablet between a closed position and an open position. The tablet is flush with the writing surface in the closed position. The document camera comprises an adjustable arm with one or two pivot points. A clip is structurally configured to lock the document camera in the lowered position.

An advantage of the present invention is that it improves the interactive learning experience by better facilitating student involvement and the sharing of information. Another advantage is the integration of a tablet or computer with a desk, which eliminates the need for complicated logistics for managing free standing devices that are often susceptible to damage, accident, and theft. Another advantage is that the present invention eliminates the need for charging stations.
