List of Digitizer Pens and Tablets

[ This is a Work in Progress page, it will continue to grow. I'll try to add a few systems every day. ]
[ Updated Dec 30, 2015 ]

Here's a list of digitizer pens and systems that may support them.  The top portion is concerned with pen names and the devices that are/may be compatible.  Definitions, and details about each technology is found at the bottom of this post.   Do note, there could be errors on this page--so you may have to do further research.  Due to finances I cannot test every system, but I would like to test the pens on some tablets that I have acquired in order to clear the mysteries.

Please note, the amazon links are one of the means of funding this type of research. The amazon links may or may not link to the appropriate system.  Lastly, as the number of systems increases the likelihood of errors also increase.  If you spot something that needs work then let me know.

NOTE: iPads (pre 2015) generally do not support digitizers.  Most of the styluses out there are "capacitive" stylus--which is very different from what you see in the rest of this page.  However, Wacom and a few other companies have been creating pens that do support pressure sensitivity via a Bluetooth module.

DEFINITIONS

---

Digitizer or Active Stylus: An electronic pen-like input device that usually offers pressure sensitivity, hover state, palm reject/cancellation and may support function buttons(usually having righ-click and erase options, but they can be modified).  Digitizers may or may not utilize batteries.  Generally digitizers have a tip that is about 1mm in diameter, but there are some in which this is not the case.  Most systems that support digitizers have palm rejection technology (it turns off finger touch as soon as the digitizer is in proximity).  The two most well-known companies in the digitizer business are Wacom and N-Trig (bought by Microsoft in 2015).

Stylus or Passive Stylus: A pen-like input device that is not electronic. Systems that support stylus are either resistive or capacitive. Resistive systems support a single point of pressure that is usually small (think of Nintendo DS, 3DS); they don't generally support capacitive stylus correctly.  Capacitive systems support finger touch input, and there are capacitive styluses that emulate those finger touches (usually the tips are greater than 2 mm in diameter and are "gummy" or "bouncy"); they don't generally support resistive stylus.  Generally resisitve systems are more precise than capacitive ones.  Stylus don't generally have hover states and other features supported by digitizers.

Digitizer/Stylus Hybrid: A pen that has elements of digitizer and stylus.  Generally these pens are stylus at the tip (meaning either resistive or capacitive) but they have digitizer features thanks to other interfaces (like BlueTooth).  Examples of these include: Ten One Design Pogo Connect and Evernote Jot Script.

Dual Digitizer: Technically, any system in which an analog signal is turned into a digital signal is considered a "digitizer". When the term "dual digitizer" is used it relates to the idea of a system that has finger touch and pen digitizer input.

Passive Stylus is often referred to a 

Note that there are systems that support the digitizer pens but do NOT support finger-touch (several Lenovo systems come to mind on this).



DETAILS

---

Apple Pencil: The pen was unveiled in 2015 and is intended to be used with the Apple iPad Pro.  From experience I can say that Apple has done a very good job.  The pen is quite simple, it is a smooth cylindrical shape, NO side buttons, NO eraser at the back, has replaceable tips, uses an internal rechargeable battery, and uses the iPad Lightning connector to charge the pen. Apple claims 12 hours of battery life.  Many pen technologies allow pen and touch, one at a time.  The Apple Pencil allows simultaneous touch and pen--in some apps you can use multiple finger gestures to enable features and then use the pen to draw--this is very good stuff and may help the pen to never need side buttons. I didn't notice a "hover" state when I used the pen.  Regarding lag I only noticed it when I had very fast strokes, for most uses you won't notice much of a lag.  The pen also has tilt detection, and pressure sensitivity.  Lastly, the "feel" when drawing on an iPad feels quite rigid, which I did not enjoy.  The distance for detection (from tip to screen) is quite short (most pen technologies are) and this can lead people to have accidental "palm clicks". Overall though, this pen and the apps are very elegant and will leave many people satisfied.

Unlike many pen technologies that support both touch and pen the Apple pen allows simultaneous touch and pen.

Asus Z Stylus: Asus digitizer that uses AAAA battery, claiming up to 150 hrs.  The pen has 1024 levels of pressure, has 1.2 mm replaceable tip, two side buttons, a status light, and clip.  The pen technology may not be proprietary (so it could be N-Trig, Wacom, Atmel, etc. I will find out)

Microsoft Surface Pen
This is a pen introduced in 2015, along with MS's Surface Book.  Microsoft bought N-Trig around April/May 2015, and this pen does have technology derived from N-Trig DuoSense technology.  A difference is increase pressure sensitivity to 1024 levels (that is 768 more than N-Trig DuoSense 2).

 N-Trig DuoSense 1 (black pen) and N-Trig DuoSense 2 (silver pen).

N-Trig DuoSense 1:  This 256 levels of pressure pen usually is identified by an aluminum cylinder shape, a replaceable tip, with one or two ellipse-like close-to-surface buttons on the side, no eraser on the back side, sometimes the back has a pen tether spot, and it uses a AAAA battery.  The tip of the digitizer is characterized by spaced rings of material, and may come in 5.5mm or 9.5mm diameters.  The pen has been used with Windows 7 and Android operating systems.  Systems that support this digitizer support several "DuoSense modes", which allow the user to turn on/off touch and digitizer options.  The pen is suited for slow and long strokes and NOT short quick strokes (think of doing math)--the result of short strokes are very blocky and straight.  The supported systems usually had a very glass-like surface to work with too.  The pen is quite precise and does not seem to suffer from erratic edge issues found in Wacom Penabled technology, however bevel of systems can get in the way of accessing GUI buttons close to the edges of the screen.  There is noticeable pointer-delay if the strokes performed are fast (most noticeable when doing the hover state).  Note that DuoSense 1 pens do not work on DuoSense 2 systems. 


N-Trig DuoSense 2: This version is similar to N-Trig DuoSense 1, but it is better.  Some differences include a tip that is closer to Wacom's classic tip, and often not advertised as being replaceable.  The pen retains the 256 levels of pressure, and systems tend to better distinguish pressure given by users.  The feel achieved when touching surfaces is still very glass-like, but is generally softer than DuoSense 1 systems.  The pen is better than DuoSense 1 at doing short fast strokes, but the inking of these small strokes is still very blocky in comparison with other technologies.  The pen also suffers from pointer-delay when in hover state.  The DuoSense 2 pens usually have two buttons, whereas DuoSense 1 pens often only featured a single side button.  The Microsoft Surface Pro 3 pen is a N-Trig DuoSense 2 digitizer, but it has an additional button on the back side (this pen uses a Bluetooth module that allows the back button to perform additional actions in Windows)--this button is not often seen in other DuoSense 2 pens.  Some models of the pen have a pen clip.


Wacom Active Electro Static (Active ES, or AES): This is Wacom's newest technology.  This digitizer does use a AAAA battery.  From my experience it seems that Wacom AES pens are not necessarily compatible with all AES systems (Lenovo's Active Pen is not fully compatible with a Toshiba Encore 2 tablet)  The AES pen is quite good, it delivers the feel of a Penabled but increases the precision.

Wacom Penabled: This is Wacom's most widely available technology, often seen in Windows convertible tablets (Tablet PCs). The pen is characterized by being cylindrical with a soft or plastic surface, may have replaceable tips, may have up to two side buttons (Some pens have no buttons.  Generally the buttons are somewhat rectangular and often do protrude--therefore easier to identify and press), may have a pressure sensitive eraser, and it does NOT have a battery.  Systems that support Wacom Penabled may have support for 256, 512, or 1024 levels of pressure (depends on the load sensor of the pen).  In many systems the pen seems precise within a certain inner area of the screen, however when the pen has  edge issues (the pointer shoots out away from the pen tip).  The angle at which a user holds the digitizer is of great importance--often holding the pen vertically gives the best precision but is unnatural to hold.  The pen has a better hover state than N-Trig DuoSense 2.  The pen is well suited for short and quick inking strokes as well as long and slow inking strokes--making it a very good choice for a variety of uses.  It is important to calibrate this pen to improve precision. Some Penabled systems deliver a very glass-like experience (X230T for example) while other systems deliver a very bouncy/gummy feel (Samsung Series 7 Slate for example), and others are in between (Lenovo ThinkPad Yoga 12 for example).  Samsung S Pens are Wacom Penabled pens.

Wacom ProPen: This line of pens are often known by their 2048 levels of pressure, are aimed at professionals, and the technology is present mostly in Wacom exclusive tablets.
