EMR Technology: What is it and which tablets use it?

Technology never stops innovating and that comes with very insane technological breakthroughs in every single industry. That’s why it isn’t shocking when a new feature has been added to drawing tablets or more specifically, something inside their LCD screens. This is called EMR and it has immensely improved the performance of these devices by leaps and bounds. It’s a fairly brand new implementation and aside from experts, almost no one knows what it is and what it can do.

That’s why we’re going to dive deeper and discover more about EMR technology. We’ll take a look at what it really is, what it can do, and which tablets already have EMR tech embedded within them.

What is EMR Technology

EMR is also known as Electromagnetic Resonance is an interdisciplinary field that you can find in Physics, Biology, and Chemistry. It’s surprising to know that EMR has several forms which include the Electron Spin Resonance (ESR), Electron Paramagnetic Resonance (EPR), and Electron Cyclotron Resonance (ECR).

However, in terms of EMR tech, it is mainly used on Drawing Tablets and is applied behind the LCD or Liquid Crystal Display. It uses an electromagnetic field present on the surface of the tablet. By pairing it with a pen that emits electromagnetic waves at irregular intervals, you get an EMR powered writing experience. There are coils inside the LCD and within the pen itself where the ones inside the tablet will receive and detect the electromagnetic waves being shot out by the pen. The closer you place the pen on the LCD, the closer the two coil goups will be thus resulting in a higher electromotive force. Certain algorithms will then use this electromotive force found in both horizontal and vertical directions to calculate and locate the X and Y coordinates of the pen.

Interestingly enough, aside from EMR itself having several forms, Electromagnetic Resonance Localization Technology also has two classifications. First of these two is the Passive classification where the pen does not require a battery making it battery-free as it uses passive wireless pressure sensing pen technology. The second is the Active classification where there needs to be a battery inside the pen to emit electromagnetic waves. This limits the size and weight of the pen because of the battery size and it needs to be charged or have the battery replaced from time to time, which may also affect the pen’s durability.

Advantages of EMR Technology

EMR Technology within tablets comes with several advantages, some of those we’ll be diving deeper on. These range from increased pen accuracy, faster response speed, to even giving artists and other users a more convenient experience through shortcut keys.

1. Accurate positioning with high precision - First off, the best advantage you can get with EMR Technology is the accurate pen position coupled with extremely high precision. As explained before, using electromagnetic waves, electromotive force, and coil groups, the tip of the pen’s location can easily be found by the tablet’s algorithm. This means that when you draw or doodle, where you place your pen is the exact spot where it will show up on the drawing tablet screen. You’ll never have to worry about your lines not matching up or your drawing looking wacky because the accuracy of the pen was not correct.

2. Advanced pen pressure sensitivity - Another advantage that comes from the pen is the advancement in pressure sensitivity. What happens here is that whenever you use the pen to write or draw, the exact amount of pressure you apply when placing it will determine the thickness of the line. It can range from 2048 pressure levels all the way to an impressive 8192 pressure levels. This means that when paired with the pin-point precision, drawing and writing on a tablet instantly rivals that of when you’re using a real pen and paper. However, unlike pen and paper, if you mistakenly apply the wrong pressure and your lines get messed up, you can easily undo it using ctrl + z.

3. Display uniformity - EMR technology also affects the way your strokes show up on your display. The uniformity of the display area of the tablet becomes better and there are no discrepancies within the screen whatsoever. That’s why you wouldn’t ever need to tilt your head just to see if the stroke was placed correctly.

4. Fast Response Speed - With EMR technology, the response speed from your pen to your drawing tablet is extremely fast. With tablets without EMR tech, there are times where the response speed is poor and you have to wait a second or two before your strokes even show up on your digital canvas. However, this time, you won’t even feel the lag and it’ll look like you're actually drawing with a brush or pen on a real canvas. So not only can you draw accurately, but you’ll be faster. This response speed eliminates the need to be frustrated as the pen output happens instantly.

5. Shortcut Keys on the Pens - Speaking of speed, with EMR technology, the pen will be able to support shortcut key functions. You can assign the shortcut key on the pen different functions such as undo, eraser mode, transform, zoom in or zoom out, and more. This makes computer operations much easier and you won’t necessarily have to keep one hand on the keys of your Drawing Tablet at all times. It’s much more convenient and especially if you’re a professional, your work process would relatively be faster.

Main Parameters of EMR Technology

We already know the advantages of EMR Technology but we must acknowledge the parameters that bring those advantages to life. There are a wide range of parameters but we’ll be focusing on the main 5 which range from Pressure Sensitivity Levels all the way to the starting activation force.

1. Pressure Sensitivity Levels - Pressure Sensitivity Levels are an important factor when it comes to assessing the quality of drawing tablet pens. Currently, with EMR technology, pens have sensitivity levels that range from 2048 levels to 8192 levels. Pressure Sensitivity affects the response time, line thickness, and quality of the pen’s outputs. The higher the pressure level, the more uniform the variation there is when it comes to the stroke thickness which means it is essential to also determine how good the outcome will be.

2. Reading Rate - Aside from the Pressure Sensitivity Levels, there’s also the Reading Rate. The Reading Rate refers to the amount of pen trajectory points the tablet can collect per second. This means that if the reading rate is higher, the tablet can receive more trajectory points. More trajectory points results in smoother lines since this also affects the tracking delay of the pen cursor. Which is why a reading rate that’s above 200 trajectory points per second is the best choice because if it’s higher than that, then it would consume your computer battery faster and might result in performance issues.

3. Coordinate Resolution - First things first, what is being meant by “Resolution” is the amount of points that can be detected in a tablet’s active area. You can capture more points by getting a higher resolution which means your lines will be much smoother. Mainstream tablets have a resolution range of 2540 lpi or at its highest, 5080 lpi or lines per inch.

4. Tilt Angle / Side Stroke - Tilt Angle or also known Side Stroke is another main parameter when assessing EMR Technology in Drawing Tablets. Line thickness variations can also be dependent on the tilt angle of the pen used. As of now, the degree range that’s being recognized is ±60 degrees.

5. Initial Activation Force (IAF) - The Initial Activation Force of IAF is the smallest amount of force that’s needed for the pen tip to activate and generate an output on the screen. If you lower the IAF, the pen tip will become more sensitive needing a lesser amount of force to be used and vice versa. It’s expressed in grams and it ranges from 1g to 30g.

What Tablets have EMR Technology?

Now that we know the advantages of the EMR Technology, what is EMR Technology, as well as the main parameters that surround its usage and assessment, we also need to take a look at the EMR Technology tablets. These tablets are updated with the latest versions of EMR Tech and are the best of the best.
