Many Colleges, Institutions, Schools use now the Whiteboards for Teaching. The Whiteboard marker uses an erasable ink which can be refilled. The Whiteboards are made of surfaces like viz Melamine, Painted steel or aluminum, Hardcoat laminate, Porcelain, enamel-on-steel.
The Whiteboards have replaced the old Blackboards with writing medium of chalk also known as chalkboard.
The Whiteboards are expensive as compared to chalkboards.
1. In terms of Technology, is there also scope for trying different materials (ink : Toluene and Xylene) used for whiteboard markers and trying other surface materials for whiteboards ?.
2. Can there will be also scope for creating new boards, marker pens, inks replacing the whiteboards and chalkboards ?.
For example : Electronic Whiteboard etc.
Electronic whiteboard -> Chips embedded within the board, Whiteboard driven by primary source of electricity i.e. Alternating current.
Portable Electronic whiteboard -> Chips embedded within the board, Whiteboard driven by secondary source of power i.e. Batteries.
etc

The Portable Electronic whiteboard may or maybe of no use for manufacturing but what came in my mind was Portability. The Major Design aspect for any portable instrument viz electronic, mechanically, electro mechanical device is compactness. i.e. Low Weight which offers east to carry the instrument.
What i feel is maybe the Portable Whiteboard could be useful fixing in the car and other four wheeler automobiles. This could be useful while discussing any topics with other people traveling in the car.

The Portable Whiteboard has to be fixed in such a way that a mirror image should fall for visualization of writing done to all people traveling in the vehicle.
The Wireless Cellular Device has limited space (window i.e. rectangular area) for explanation.
Can we manufacture Wireless Electronic Whiteboards ?.
The Electronic Whiteboard (Receiver) has chips embedded to receive the signals
via the Remote control. The Remote Control has interface similar to a Cell Phone Device
i.e. able to type all characters, numbers, special characters etc.
The User can type the characters through the remote control device which can be visualized on the Electronic Whiteboard.
We can try Cellular Wireless Remote Device for typing characters replicated exactly on the LCD / LED Television Set before manufacturing a Wireless Electronic Whiteboard.

I am a teacher and doing job in school from last six years, Last year I was faced a back pain problem and facing till now.
I am not able to write on blackboards now i am using portable whitebaords and it works for me.
Thanks

When one stretches their arm a great distance from their core, so that the weight of the shoulder, arm, and hand, as well as the precise movements required for finger dexterity supporting/pinching/controlling pen or chalk....well, you see the nerve/tendon traffic jam problems that can arise in the lower/mid/& even upper back region.
Try to maintain your arm movements closer to your center core. This may mean the student must wait in anticipation for the teacher to move out of the way of what is being presented.
Strengthen the back region (with medical permission) with buttock/stomach muscle tightening sets, sit-ups, crunches, and standing torso twists, rotating your out-stretched arms slowly to the forward position, keeping your head and view stably forward during the process. You can use a broomstick, curtain, or closet rod as an extra prop across your shoulders, behind your neck, resting your arms and hands on it while you perform the twists. (The trick is to keep looking forward throughout, as it gives emphasis to the back twist--ones feet should not be tight together, nor separated further than the distance between the shoulders).
