BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention generally relates to manipulation devices for selecting and/or moving electronic images on a graphical user interface. More particularly, the invention relates to a manipulation device for selecting and/or moving electronic images on an interactive whiteboard.
2. Background
An interactive whiteboard (IWB) is a large interactive display device that is operatively connected to a data acquisition/data processing device (i.e., a computer) and a projector. In a typical arrangement, a projector projects the desktop of the computer onto the interactive whiteboard's outer front surface such that users are able to control the computer using a finger or other device. The interactive whiteboard is typically mounted to a wall, and thus, is elevated a substantial distance above the surface of the floor.
Recently, interactive whiteboards have become very popular in educational institutions because they offer teachers an interactive means by which traditional school subjects can be made more appealing to students. In fact, it was expected that, by sometime last year, one in every seven classrooms in the world would have an interactive whiteboard installed therein. Interactive whiteboards are becoming commonplace not only in secondary schools, but also in primary schools.
While interactive whiteboards are very useful teaching devices, it is not always easy for users to manipulate objects on the display surface of the interactive whiteboard. This problem is particularly prevalent among the younger children in primary schools. Many of these children have great difficulty in moving objects across the interactive whiteboard display surface with their fingers. To compound the problem, many of the interactive whiteboards in primary school classrooms are mounted at a height on the wall that is not readily reachable by young children who typically have a small stature. Consequently, because it is difficult for young children to manipulate objects on the interactive whiteboard, their enjoyment of the potentially valuable learning experience offered by interactive whiteboards is greatly diminished. In addition, because the lessons being taught by teachers are being continually disrupted by the inability of the children to effectively utilize the interactive whiteboard, their enjoyment of activities being performed on these whiteboards is likewise decreased.
Therefore, what is needed is a device that facilitates the manipulation of objects on the display surface of an interactive whiteboard, and an interactive teaching system that employs the same. Such a device would greatly enhance the interactive learning experience facilitated by interactive whiteboard systems, thereby enabling students and their teachers to realize the substantial benefits offered thereby.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
An embodiment of the manipulation device is seen generally at 1 in FIGS. 1-3. The manipulation device 1 of the depicted embodiment comprises a body portion 10, an elongated rod 20, and preferably, a gripping device 22. As seen in FIGS. 1-3, the elongated rod 20 has two oppositely disposed end portions. The body portion 10 is connected to the first end portion of the elongated rod 20, whereas the gripping device 22 is disposed around the outer circumference of the second end portion of the elongated rod 20. In a preferred embodiment, the manipulation device 1 is configured to be used with an interactive whiteboard system. The manipulation device 1 greatly facilitates a manipulation of objects on the interactive whiteboard by a user thereof.
Referring to FIGS. 2 and 3, it can be seen that the body portion 10 of the manipulation device 1 comprises a thin layer of foam 12 disposed on the back side thereof. The inner, front surface 12a of foam layer 12 is affixed to the rear surface of the body portion 10 by a suitable adhesive, such as hot glue or a clear, multi-purpose craft adhesive (e.g., E-6000®). The rear surface 12b of the foam layer 12 contacts the outer viewing surface of the interactive whiteboard. The foam layer 12 contributes substantially to the overall functionality of the manipulation device 1 because it greatly improves the interface between the manipulation device 1 and the interactive whiteboard by increasing the frictional contact between the two adjoining surfaces.
In a preferred embodiment, the thin layer of foam 12 comprises a closed cell, ethylene-vinyl acetate (EVA) craft foam or a polyethylene (PE) craft foam having a thickness of approximately 5/64 of an inch (2 mm), a hardness of 40 shore c, and a density of approximately 145 kg/m3. However, it is to be understood that other types of foam having different material properties can be used without departing from the spirit and scope of the invention, provided that such other foam materials are suitable for manipulating objects on an interactive whiteboard.
While developing the present invention, the inventors found that craft foam grabbed electronic objects on the interactive whiteboard display surface much better than the other materials that were tested. In particular, during the development of their invention, the inventors tried various other materials, such as a cloth material, a tennis ball composite material, felt, and closed-cell extruded polystyrene (i.e., Styrofoam®). However, unlike the preferred thin sheet of craft foam, each of these materials did not suitably manipulate objects on the interactive whiteboard. Rather, these other materials tended to slide across the outer display surface of the interactive whiteboard without effectively grasping and moving the object being manipulated by the user.
Now, turning to FIGS. 4-6, the features of the body portion 10 of the manipulation device 1 will be described in detail. In a preferred embodiment, the body portion 10 has a semi-ellipsoidal shape, or partial egg shape. In particular, the body portion 10 is approximately in the form of a half-ellipsoidal solid, with a geometry that is characterized by an ellipsoid that has been split substantially in half along a longitudinal center plane, which contains the major axis of the ellipsoid therein. Referring initially to FIG. 4, it can be seen that the body portion 10 comprises a curved front side 14 and a substantially flat back side 16. As described above, the front surface 12a of foam layer 12 is affixed to the substantially flat back side 16 of the body portion 10. A circular hole 18 is provided in a bottom portion of the curved front side 14 of the body portion 10 for receiving the first end 24 of the elongated rod 20 (see FIGS. 5 and 7). The circular hole 18 has a substantially flat bottom disposed internally within the solid body portion 10 against which the first end 24 of the elongated rod 20 is pressed when the manipulation device 1 is being assembled.
In a preferred embodiment of the invention, the diameter of the hole 18 in the body portion 10 is approximately five sixteenths ( 5/16) of an inch. Also, in a preferred embodiment, the distance D from the bottom edge of the body portion 10 to the bottom edge of the circular hole 18 is approximately three sixteenths ( 3/16) of an inch (see FIG. 5). However, it is to be understood that these specific dimensions are merely exemplary, and that other suitable dimensions can be used without departing from the spirit and scope of the invention.
The inventors of the present invention chose to form the body portion 10 using a semi-ellipsoidal shape or partial egg shape for several reasons. Most importantly, the curved ends of the ellipsoidal shape (see FIG. 6) enables the manipulation device 1 to have a smaller back surface 16 with which to manipulate and drag objects on the interactive whiteboard, thereby increasing its overall functionality. Also, the narrower tip portion 50 of the semi-ellipsoidal body 10 (see FIG. 6) is ideal for pointing to various objects that are disposed on the outer display surface of the interactive whiteboard. In addition, the curved front side 14 has a large surface area that is particularly well-suited for accommodating decorations. The oval periphery of the body portion 10 also facilitates the various design schemes that the inventors have developed for the manipulation device 1.
In a preferred embodiment, the length of the semi-ellipsoidal solid that is used for the body portion 10 has a length extending in the direction of its longitudinal major axis of between approximately one and one-half (11⁄2) inches and approximately two and one-half (21⁄2) inches (or between one and one-half inches and two and one-half inches), with lengths of approximately one and one-half (11⁄2) inches, two (2) inches, and two and one-half (21⁄2) inches being the most preferred. Also, in a preferred embodiment, when a semi-ellipsoidal solid has a length approximately two and one-half (21⁄2) inches, it has width of approximately one and three-eighths (13⁄8) inches in the location of its minor axis. However, one of ordinary in the art will appreciate that the present invention is not limited to these aforedescribed lengths and width. Rather, other lengths and widths for the body portion 10 may be used without departing from the spirit of the invention, provided that the selected length, width, and overall size of the body portion 10 does not have deleterious effects on its functionality. For example, if the body portion 10 was formed using a length of greater than two and one-half (21⁄2) inches, it may become too heavy and cumbersome for use by small children who have limited strength and small hands.
Also, while it is preferred to form the body portion 10 from a semi-ellipsoidal solid, it is to be understood that the present invention is not so limited. Rather, the inventors have contemplated using spheres and prisms for the body portion 10, as possible alternatives to semi-ellipsoidal solids.
Next, the elongated rod 24 of the manipulation device 1 will be described. As shown in FIG. 7, the elongated rod 24 comprises a first end 24 and an opposite, second end 26. The first and second ends 24, 26 define the longitudinal extents of the elongated rod 20. The first end 24 of the elongated rod 20 is inserted into the hole 18 of body portion 10, and the two components 10, 20 are secured together using an adhesive, such as hot glue or a clear, multi-purpose craft adhesive (e.g., E-6000®). The second end 26 of the elongated rod 20 is grasped by a user while he or she is using the manipulation device 1 to manipulate objects on the interactive whiteboard. In a preferred embodiment of the invention, the second end 26 of the elongated rod 20 is provided with a gripping device 22. As best shown in FIG. 1-3, the gripping device 22 preferably covers approximately at least one-sixth (1⁄6) of the overall length of the elongated rod 20 so that a majority of a user's hand contacts the gripping device 22, rather than the outer surface of the elongated rod 20. This design enables a user to maintain a better grip on the manipulation device 1 when he or she is moving it across the outer surface of the interactive whiteboard. The gripping device 22 is preferably formed from a generally annular rubber grip.
In a preferred embodiment of the invention, the elongated rod 20 has a diameter of approximately five-sixteenths ( 5/16) of an inch and a length of approximately twelve (12) inches. Using a diameter of five-sixteenths ( 5/16) of an inch for the elongated rod 20 is advantageous because it is small enough to be easily grasped by the small hands of children. Also, because some commercially available gripping devices 22 are formed using an inside diameter of approximately five-sixteenths ( 5/16) of an inch, the selection of this particular diameter reduces the manufacturing and/or assembly cost of the manipulation device 1. Selecting an overall length of twelve (12) inches for the elongated rod 20 improves the functionality of the manipulation device 1 because it provides sufficient length such that users of a small stature, such as young children, are able reach the top part of the interactive whiteboard without using a stool. Because stools pose a safety hazard to small children, alleviating their use when teaching sessions are being carried out on an interactive whiteboard is highly desirable. While it is preferred to form the elongated rod 20 using the dimensions aforedscribed, it is to be understood that the present invention is not so limited. Rather, the elongated rod 20 can be formed using other diameters and lengths, provided that these other dimensions for the elongated rod 20 are congruent with the intended functionality of the elongated rod 20.
In a preferred embodiment, both the body portion 10 and the elongated rod 20 of the manipulation device 1 are formed from wood. In this preferred embodiment, the body portion 10 is formed from a wooden egg-shaped solid that is vertically cut in half, whereas the elongated rod 20 is formed from a wooden dowel rod. However, one of ordinary skill in the art will appreciate that the body portion 10 and the elongated rod 20 can be formed using other suitable materials without departing from the spirit and scope of the invention such as, but not limited to, metal or plastic.
In FIGS. 8-18, a plurality of different embodiments of the body portion 10 are depicted. The inventors of the present invention have developed various design options for the body portion 10 in order to make the manipulation device 1 more aesthetically pleasing, and more attractive to the users thereof. For young children, these designs involve decorating the body portion 10 so that it resembles various types of animals. In FIGS. 8 and 9, the body portions 10 are designed so as to resemble a penguin 28 and a mouse 30, respectively. Similarly, in FIGS. 10, 11, 12, and 13, the body portions 10 take the form of a monkey 32, a pig 34, an owl 36, and a cat 38, respectively. Finally, in FIGS. 14-18, the body portions 10 are designed so as to resemble a bird 40, a cow 42, a sheep 44, a dog 46, and a fish 48. In addition to the animals that are explicitly depicted in FIGS. 8-18, the inventors have also contemplated decorating the body portion 10 so as to resemble the following other animals: a frog, a squirrel, a bear, a lion, a dragon, a horse, miscellaneous bugs, a goat, a raccoon, a zebra, a tiger, an elephant, a ladybug, miscellaneous birds, and a parrot.
A perspective view of an interactive teaching system is illustrated in FIG. 19. As shown in this figure, a user 52 holds the elongated rod 20 of the manipulation device 1 in her hand, and uses the manipulation device 1 to select and/or move electronic objects 56 on the display surface of an interactive whiteboard 54. During the utilization of the manipulation device 1, the user 52 contacts the outer display surface of the interactive whiteboard 54 with the foam layer 12. The manipulation device 1 with the foam layer 12 attached to the back side 16 thereof greatly enhances the ability of the user 52 to effectively manipulate the objects 56 on the display surface of the interactive whiteboard 54. While not explicitly shown in FIG. 19, the interactive whiteboard 54 is operatively coupled to a data acquisition/data processing device (i.e., a computer) and a projector. The projector projects the desktop of the computer onto the interactive whiteboard's outer front surface.
In FIGS. 20-22, another embodiment of the manipulation device is depicted. As shown in FIG. 20, the front side of the body portion 10 of the manipulation device 1 preferably is decorated so as to resemble a particular type of animal (e.g., a cat). The side perspective view of the manipulation device 1 shown in FIG. 21 clearly illustrates the semi-ellipsoidal shape of the body portion 10. A rear perspective view of the manipulation device 1 is depicted in FIG. 22. It can be seen in this figure that the body portion 10 is provided with a foam layer 12 disposed on substantially the entire back surface thereof. As previously described, the foam layer 12 greatly facilitates the manipulation of objects on the display surface of the interactive whiteboard.
Although the invention has been shown and described with respect to a certain embodiment or embodiments, it is apparent that this invention can be embodied in many different forms and that many other modifications and variations are possible without departing from the spirit and scope of this invention. For example, the elongated rod 20 can be provided without a gripping device 22 (refer to FIGS. 23-25). In such an embodiment, the user of the manipulation device 1′ would simply grasp the exposed second end portion of the elongated rod 20. Moreover, as another example, the body portion 10 can be decorated using designs that are not in the form of animals. For example, in order to make the manipulation device 1 more appealing to older children, the body portion 10 could be decorated using simpler designs, such as stripes or polka dots.
While exemplary embodiments have been described herein, one of ordinary skill in the art will readily appreciate that the exemplary embodiments set forth above are merely illustrative in nature and should not be construed as to limit the claims in any manner. Rather, the scope of the invention is defined only by the appended claims and their equivalents, and not, by the preceding description.
