Touchscreen PCs: 3 Things to Change

by - source: Tom's Hardware US

Two-point multi-touch? Check. Responsiveness for all? Well...

As we finally tried out the MSI Wind Top AE2280 (available at the company's COMPUTEX 2010 booth), three badly needed changes to Windows touchscreen PCs came to mind.

Always provide enough resources for responsiveness

MSI's offering was powerful enough to respond immediately to user touch-input. Why shouldn't it be, with at least a Core i3 530 and 4 GB of DDR3 memory? However, not all tablet PCs however are that responsive. The Lenovo ST10-3t we tried out was a very compact 10" swivel tablet PC, but with only 1GB of RAM onboard, many touch commands suffered from interface lag.

For a touch interface to be truly useful, it has to react immediately. Once the user taps, something should instantly happen. Companies shouldn't release tablet PCs that don't have the hardware required for a responsive user experience.

Build more fuzzy logic into the system

Users are notoriously imprecise and inconsistent, which is why interface systems shouldn't be too obsessive-compulsive. The Wind Top's touch controls are similar to Apple's "original" system, but some gestures need a relatively inconvenient degree of precision before working properly. In other words, we sometimes had to do our gestures "properly" to get the Wind Top to recognize them. That took us longer that we liked, so we unconsciously reached for a mouse and keyboard once again.

While randomly moving your fingers around a touchscreen shouldn't result in anything, perhaps the detection system should be a little more forgiving?

Get rid of those damn raised bevels!

True tablet PCs, the ones that are basically digitized slates, get it right: make the display flush with the supporting frame so that people have more space to tap their fingers on. At the same time, this makes it much easier to tap items on the corners of the display. The user doesn't have to take care to keep their finger away from the bezeling as much as possible in this configuration.

So why do PC manufacturers like MSI and Lenovo insist on the classic monitor configuration, with the surrounding raised slightly relative to the actual screen? Make everything one flat plane, and tapping everywhere becomes much easier.

What about you?

How has your experience with Windows touchscreen PCs been? Whether or not you think it needs improving, feel free to share your comment below.

To me, touch PCs aren't really attractive. I still love my mouse/keyboard combo. I do own an iPod Touch and a Motorola Milestone, but I can't live without a keyboard.

Once this happens, Touch Porn will be the new thing.

One flat plane would work great for touch screens, however my "almost" one flat surface touchpad/keyboard wrist rest on my laptop makes it so my hand is sending the mouse flying when i type. I miss a good bezel

Wacom should handle touch screens, along withe the option to switch to stylus at the press of a button (or gesture)?

I agree. Especially about the raised bezel

agree with the article.

Just for the heck of it I tried an iPad while at a Best Buy store. Typing seemed awkward.

Totally agree. My hp tx2500 is powerful enough, but the raised bevel gets in the way of closing windows all the time. It could also use more "fuzzy" detection logic. More often than not I'll reach for the Wacom pen if I'm using it in slate mode. I primarily use touch just for switching windows by taping on the taskbar.

Unfortunately, styluses are a thing of the past when multitouch capacitive touchscreens are all the rage these days. I for one prefer my single touch resistive touchscreen on my Nokia that works with a stylus (for handwriting recognition) or my fingers.

Button to switch to stylus? That statement is confusing to me. They are recognized as two separate devices for me. You use the pen or the touch screen and they just work. It's like asking for a button to switch between using a keyboard or a mouse. They simply both work, all you need to do is actually use the one you want.

i think touch PC's are awesome and i'd love to have one. However I still love the use of keyboards..so even though i can type well on my iphone, a keyboard with a touch PC would be great

Totally agree with you.

About the raised bezels - they should come up with very durable screens should it be a flat faced device.

Evolution needs to give the human race a fully functional third arm. That way you can hold your iPad (or other tablet) while still being able to utilize two handed computing. But that's neither here nor there.

Yes and no...

Using stylus while having touch screen on may have problem when you rest your hand/wrist on the screen while writing.

This can be solved at the OS or software level but I am not sure have they solved this problem or not.

You can't use a touch screen, which stands vertically, for more than 10 minutes.
What's that for?

I know that at least Windows Vista and Windows 7 have "palm detection." It works pretty well for me, I can write normally with my hand resting on the screen without activating the touch screen.

They've had similar "palm detection" for laptop track pads for while you are typing on the keyboard and your palm may rest on the track pad.

True. I find the convertible notebook/slates makes a lot more sense than these upright desktop all-in-ones.

yes, and ... they should allow people to install (or have the salesperson install) and play with their program of choice in store ... I won't buy one until I can try out the poker programs I favor.

Or maybe I'll buy it and if it doesn't work to my satisfaction, just return it

Or PCs for that matter.

"Fuzzy Logic" has very little to do with what the article asks to improve.

I've had very little experience with touch-screen PCs, but it always felt slow and inaccessible. The All-in-One desktops tend to use laptop hardware (even integrated Intel graphics), which are not very responsive when you have full-screen customized interfaces. Those full-screen interfaces also make me feel cut off from the system and tools I'd usually have access to like Task Manager or the Start Menu and are more focused on showing off pictures or playing videos: but 99% of what I do with a computer is not watching vacation slide shows or using it like a TV.

I still don't see the point in desktop touch-screens, obviously there are advantages on the move, but with a 19" desktop monitor, it's only just going to be within reach if you have your desk set-up nicely, if you have a bigger monitor, you could easily be sitting out of arms reach of it...

personaly I think that the bazel i there to protect the screen becouse if you put it sreen down so it wouldnt scratch

I just want to be able to buy a touch-screen monitor to go with my existing desktop computer, which will automatically be better than any tablet they produce (unless the tablet costs like $3000).

most laptops have a key to disable the touchpaad or can do it via a driver when an external mouse is connected

Touch screens need to be "Doritos-hand" proof.

I have had hours of time working with both MSI and HP touchscreen computers and one of the things that I've noticed is that they're all a glossy glass display which doesn't slide very well. If your have rough fingers or dry skin on your fingers, theres a lot of skipping and movement problems. Maybe a softer material would make it easier to move and less fingerprints on the display

They have.

My laptop (HP Pavilion tx2500z) also has a slate mode. It has both a capacitive touch screen for finger input (single-touch) as well as a stylus for pen input (from wacom). Both work simultaneously. When the pen is at least hovering over the screen, it disables capacitive touch (it is not required for the pen). If the pen is not near the screen, you can control it with your fingers to your hearts content.

And this was in 2008.

People really haven't been paying attention to the tablet market. All of a sudden, it's all new tech. But that's what happens when Apple releases a product. It's been around but just didn't have the eyes of the general consumer market on it until Apple steps in.

HD TV has been around for decades but it is still catching up, isn't it? So maybe it is just that Apple is doing it right and they are better at marketing. ;) And I'm not an owner of Apples gadgets.

As I always say, they rarely innovate with new products. They just take an existing one and improve upon it, and then throw their marketing weight behind it. Not that it's a problem, because it isn't. It's just how things go. :P
