Windows 10 tablet with pressure sensitive stylus

Hi,
I'm looking for a Windows 10 tablet.
I would like to use it with a finger or a pressure sensitive stylus.
I've just found several models on Banggood nammed "stylus".
They are sold without stylus.
I didn't find if they are pressure sensitive.
I'vre read somewhere that several models are. With Wacom compatible
stylus but can't find which models.
Can someone tell me where could I find such an information ?
Which Brand / model ?
Where I could buy this kind of tablet ?
Thanks,

I think you'll find Watcom stylus to be pressure sensitive regardless of
the OS. Believe that's part of what the driver provides rather than the
OS itself. Least that's the way it seemed when I used to use mine.

I also would think if a built-in trackball was pressure sensitive they'd
be advertising it.

Take your stylus with you and visit a computer shop.

Thanks but tablet need to support pressure sensitivity.
Websites as BangGood don't speak about pressure sensitivity.
I can't find ont the web what are the tablets that are pressure
sensitive.

AFAIK, the only tablets that are pressure sensitive are peripheral devices
designed for making drawings with a stylus. Is that what you have in mind?

Windows 10 tablets are handheld PCs. Their touch screens are sensitive to
local changes in electric charge (capacitance). Technical improvement have
made these screens high-resolution. IIRC, on a Surface tablet it's about 2mm
with fingers, and about 1mm with the stylus. Very like a smartphone.

Have a good day,

Thank you,
Not sure to be clear, sorry.
I'm looking at a tablet that would be able to detect drawing pressure
with a stylus.
It seems that Win10 tablets called "stylus" have this capability but I
can't be sure.

For example, "Cube i7 on Gearbest" :
"Classic operating modes: You can buy a keyboard to turn it into a real
portable laptop, or you can buy a Wacom touch pen (1024 level of
pressure) to enjoy the delight of precise and smooth writing / drawing
experience."
This is the only example I've found.

So I'm looking at a tablet, working on Win10 that have a screen which
is able to detect drawing pressure. Then I'm looking on a compatible
stylus.
This information seems to be impossible to find on the web...
I'm looking at this for several days.

Looks like an, er, imitation of the Surface.

However, AFAIK, all styluses work on capacitance. I don't understand the
reference to pressure on Gearbest's website. It's rated "untrustworthy"
by WOT, BTW.

Have good day,


An active stylus with a deformable tip, can
use a strain gauge to measure (Z). Combined
with the (X,Y) coming from the regular touchscreen
surface.

A passive stylus may have a rock-hard tip which
does not deform. Whereas an active stylus can
have a strain gauge in the tip. And the tip has
to deform easily (i.e. be soft), as otherwise
the user will apply too much pressure to the screen.

AFAIK, none of the styluses available for tablets (handheld computers)
are active.

Maybe read this.

I was pondering the problem of how best to sense such pressure data (Z
axis) and had come to the conclusion that the simplest and most reliable
method would best be implemented by incorporating the pressure sensor in
the stylus itself, i.e. an 'active' stylus.

Such a stylus would need either a wired connection or some flavour of
wireless (proprietry to the touch screen/pad or, pretty much the ideal,
BlueTooth). At such close range (you could hardly get any closer than the
contact between stylus and the touch screen or pad), a nanowatt Tx in the
stylus would make for long battery life, allowing the use of a very tiny
cylindrical LiPo battery more than small enough to be eliminated as a
limiting factor in the dimensions of the slimmest of stylii.

As for the tip of such a stylus needing to be soft and compliant, that
would primarily only be to minimise damaging wear and tear on the touch
screen or pad rather than to assist in detecting pressure. Pressure
sensing load cells are generally designed for minimum compliance in most
cases (just think of it as the mechanical force equivalent of the ideal
ammeter - zero volt drop sensing of current).

Indeed, in many cases, the very structural fabric of whatever needs to
be monitored for pressure/tension stress forces (e.g. a road or railway
bridge) is converted into a "Load Cell" by glueing strain gauge strips in
an X pattern onto the parts of the structure that need to be monitored,
parts that remain as stiff and uncompliant as the designers first
intended (which, in most cases, is about as stiff and uncompliant as can
possibly be achieved).

Otoh however, it is possible to design a touch pad (or even a touch
screen) which can detect such pressure (Z axis) information without the
need for an active stylus. One (reasonably reliable) way would be to
support the sensing surface on load cells at each corner such that the
total forces could be summed to calculate the total force applied by the
stylus tip regardless of its contact position on the touch pad or screen.

The touch pad or screen would only need to be stiff enough to avoid
excess deflection compromising the user experience as well as to avoid
being distorted into contacting the load cell supporting structure before
exceeding the maximum calibrated pressure range of the stylus applied
forces.

One major consideration in such a design (and to a much lesser extent in
the case of an active stylus) is the need for dynamic zeroing calibration
of the Z axis, both for drift compensation and orientation changes of the
touch screen surface in the case of a tablet computer (a separate touch
pad or active stylus would only require drift compensation which could be
achieved manually by the user).

As to which of these two possible methods of harvesting the Z axis
sensor data is actually employed in practice, I can only make an educated
guess. I'd imagine a touch screen tablet PC is more likely to use an
active stylus option whilst a high grade touch pad is more likely to use
the pad itself to sense stylus pressure using a passive stylus. Both
methods have their pros and cons.

When looking for a tablet PC that supports pressure sensing, I'd expect
a key specification would be support for an active stylus option to sense
the Z axis parameter. However, don't discount the possibility that the
touch screen might incorporate pressure sensing without the need for an
active stylus. The key to your search would be to look for a reference to
not only the term 'pressure' but also the term 'Z axis'.

After reading the current posts, I still don't know what you're trying
to accomplish, however, there seems to be some confusion about the
styli. Wacom has had pressure-sensitive styli for decades, and that
capability is accomplished via the Wacom drivers. So, any tablet that is
supported by the drivers, which would be most tablets running any
version of Windows, would respond to the pressure-sensitive action of
the Wacom stylus.

All I can report is that my old Lenovo X200T tablet convertible laptop
did Wacom pen and (via the resistive screen) finger touch on Windows 7,
but to make it work on Windows 10 I've had to install an older driver
and disable updates by saying I'm on a metered connection.
X200T's built from the month after mine had capacitive screens and I
haven't tried them or later X20x series.
I have used the pressure sensitive features of Wacom pens on other old
Lenovo tablets, but not bothered yet with this one.

The pressure sensitivity seems to come from the drivers, although I
don't understand how, as Chinese copy pens seem to work just as well.
