The digital pen is often confused with other electronic gadgets like the stylus to simplify interaction on touch screen interfaces like IWBs (Interactive Whiteboards) and tablets or the pen scanner to read using a sensor the writings and symbols printed on paper.
The digital pen, electronic pen or smart pen is a computer tool that looks like a classic ballpoint pen but does not work like the latter, although it is also used for writing and uses ink. What sets it apart can interact with the screen of a computer or tablet.
It records handwritings or drawings on paper and then transmits them instantly to a computer. Simply put, the digital pen is quite simply a smart tool that converts everything you write or draw on regular paper into digital format. But it must be associated with a digital notebook. Aside from its function of writing like a traditional pen, it also has a transmitter function so, gestures and movements are captured and recorded by a receiver which is then directly interpreted on the computer or the tablet.
The Receiving Clamp Pen
The first has a receiver called a clamp. The latter is to be placed on the upper part in the middle of the sheet. This clamp will locate and calculate the position of the pen on the sheet. After the handwritings or the drawings, the clamp will be connected to the computer for digitization. The connection is similar to that of a USB stick. The indications are directly visible on the screen. Data can be saved in different formats.
The Pen With Halftone Paper
The second is a technology that works on-screen paper with several pre-printed micro-dots programmed to locate whatever is written or drawn on the page. Invisible to the naked eye, these micro-dots serve as a matrix on the sheet and allow the position of the pen to be intercepted. The transmission of writings and drawings to the computer is done by a wireless transmitter or a USB connector. For each of these models, there are dedicated applications to install on the computer or the tablet to allow viewing and recognition of the notes.
Using The Digital Pen
You will find several models of digital pens, and they can be used in different ways depending on their technology. This computer tool that instantly scans handwriting printed on regular paper can be used for taking notes and capturing writing and plots that you can then save, edit and export to your computer. They are therefore transferred in real-time to the screen for modification.
Also, the digital pen can be used as a mouse. In the education sector, it is used for correcting exercises. The teacher will no longer have to travel to the board to correct. But for this use, the pen must be associated with a TBI connected to a projection device.
