This would be a whiteboard with a two dimensional inkjet printer-type head that moves across the surface of the board and prints whatever the operator writes on their tablet pc style controller. There would be a paint shop type color menu, and two erasing options.
One option would be an "erase
all" feature that moves a stick across the entire board, or another where the person outlines the desired section with a box, similar to the click-and-drag highlighting option in windows, and then that person can select to erase just that section.
Another option would be to take "snap shots" of a certain section on the board to be recalled later. The recall option would be good for live presentations, or a quiz or something.
Other options could include automatically changing dates, and handwriting recognition. One advantage of this over an overhead projector or video projector are that there is no focusing, and no bulbs to replace. A drawback is replacing the "ink" cartridges. There are two possible solutions for this: Make a carrier that, instead of cartridges, holds two or three markers that it can push against or pull away from the board. Another option would be to design a some type of inkjet system meant to actually last (is the reason they put it in the cartridges because they couldn't figure out how to make it last?) and the person can simply refill it with bottles of the "ink". One other advantage to this is, if it breaks down, it can be used as a regular whiteboard, and is not susceptible to power failures. Also, if one could spring for a cheaper controller, the board mechanism might be slightly cheaper than a video projector.

No problem to bake this one. Take a flatbed plotter (link), turn it vertically, and change the pens to dry erase pens (and one eraser-shaped pen). The only question I ask is why? Seems like it's a lot more trouble than the handwritten method. |
|
| |
When I used to use pen plotters the color was selected by rotating a wheel so that the desired cartridge was in the drawing position. Then instead of moving the pen to draw, the paper moved around beneath the pen, so right now I have this very funny vision of a whiteboard flying all over the place. Don’t worry – I’ll get over it. |
|
| |
College used to have one of those big HP pen-plotters that would zip the paper and pen back and forth at incredible speed, daring people to dodge it like some weird game of chicken. It was always much more fun than the new laser-printers that just benignly spit out the draft. |

I like the idea. We already have whiteboards that scan and print out your writing on fax paper. The problems are: |
|
| |
(a) they they rotate three sreen panels on conveyor belt and this is rarely enough so you end up erasing info you'll need to show again later |
|
| |
(b) they cannot undelete text you wish you hadn't erased |
|
| |
(c) You must manually write on the board |
|
| |
There are projector systems, but they don't have the flexability of on-the fly writing |
|
| |
If I were to bake [Dimandja]'s idea, I'd use a conventional whiteboard connected to a PC. That would allow the user to rapidly auto-draw pre-created stock slides and images and redraw deleted stuff. |
|
| |
I'd mount a large format inkjet head in the frame at the same side of the board to the scanner. This way the scanner would be able to see what was already written. Pressing rewrite would write over the space not still covered in ink. |
|
| |
The device would have a 10" SVGA monitor that could be used to preview scanned screens much like the play feature on a digital camera. That would save you the embarrasment on printing out graffitti accidentally stored earlier. |
|
| |
You know, I've just had an easier-to-implement software-based idea. |
|
| |
If you have ever given a presentation from a laptop and projector setup, you'd know that it's pathetic to use a laser pointer or an extendible aerial-type pointer. |
|
| |
What we need is a MS-Office plug-in or a third-party software app that would work like one of those football-play pens they use on TV. This would work as an overlay on the screen and run on a conventional tablet PC and an LCD projector set-up. |
|
| |
It can't be too difficult. I'm sure there is already software like this available as shareware or built into the tablet-OS |

I recently visited my old school and found that they had spent thousands on the IT equipment. Amoungst the gleaming iMacs was a special white board that acted like a touchpad. A screen image was projected onto it using a standard projector, and aligned using software. It was then possible to do anything you could do with you mouse on the board with you finger. It also had dry-pens (no ink - projected lines on the screen) and an eraser. Not a printer, but I think this is a better way of doing it. The projector focuses its elf, and the bulbs dont have to be changed as often as cartridges. |

[Worldgineer] The purpose for this is that, at my school, both a disabled elderly teacher, reduced to his motorized cart, and pregnant algebra teacher, who faints when she leaves her chair, could both use something like this. For the elderly teacher, an overhead or computer is also cumbersome and uncomfortable during a demonstration (he's a chemisty teacher). A tablet pc like device he could hold in his lap. The pregnant teacher could use this without having to leave her chair. Also, our a/c system sucks and any kind of projector makes the rooms unbearably hot. (Admin, I apoligize for adding this on in an anno instead of the idea body, but then I don't think anyone would notice it, I know I wouldn't take the time to read the idea again just to see if the person added something.) |

[Dimaja], I don't beleive any of the whiteboards in your link have an ink jet head that can print on the board itself, but I'll leave your link just the same. |
|
| |
Er, Dimandja, whatever you think of the idea, your link does not Bake it, by your own admission. |

[DrCurry] Thank you
[Dimanja] I like the mechanical way, because it's less technology you have to teach a person, if it breaks down, you can use it like a regular board until it's fixed, and in case of power failure, nothing's lost. Also, did I mention that my school's air conditioning system is virtually nonexistent, making any projector or thing with a bulb an object of hate, because it makes the rooms unbearably hot? |

what [miasere] said, smart whiteboards are great, everyone should have one. I'd never return to a real one, given the choice. |
