PlayStation Touch Screen for Your Linux Box

hebertrich writes to tell us that IBM DeveloperWorks has an interesting article about how to modify a PlayStation LCD for use as a touch screen panel for your Linux box. From the article: "Historically, the lack of friendly interfaces has been an obstacle to making Linux® a commercially viable product for end users, but with available GUIs, that's yesterday's news. What's the next step in creating an easy-to-use Linux-based product for consumers? Imagine adding a user-oriented LCD touchscreen. A touchscreen facade can make back-end Linux applications very usable in such devices as custom digital media centers (either in the home or in automobiles), DVRs and PVRs, and even control interfaces for household robots."

Obstacle to making Linux commercially viable

If lack of a touchscreen was holding linux back, a procedure that requires cracking something else open, cabling and soldering will not be winning you new converts or my grandmother.

Things like this were best summed up by Rasterman (author of enlightenment) when he was asked if he felt linux would be "ready for the desktop". He said something to the effect of, "No, the desktop battle is over, linux didn't win. Don't waste your time trying to fight the desktop battle. Instead, put linux on people's cell phones, their toasters, on their PDAs. The future is in embedded systems. That's where linux can win." He's right. I think IBM understands this too. What things like this article do is, instead of helping a company sell something, they help a developer build something. That developer can then take a working prototype to potential investors without having to go to the trouble of finding parts distributor's and whatnot before testing their idea. They can just buy a PS1 at a junk store and strip it for parts. Once the investors give them an investment, thanks to the help of the working prototype, they can drop the big cash on custom components if need be and even buy in bulk.

So yes, this is a huge help. Developers don't just write office software after all.

So what do you do at IBM?

I write articles such as the one mentioned above. I get payed to think and work on things that are eventually free.

Man, what a job.

Hmmm...

I wonder if touchscreens such as this could function on ADC (Apple Display Connection), which integrates both DVI-I and USB into one plug... That way, a separate serial/USB cable for transmitting HID data wouldn't be necessary.

Think of the possibilities

Nethack Touch Screen Edition, you could... finger finger, finger bash, finger fsck... you get the point.

Touchscreens. The universal UI panacea. Well, apart from speech recognition.

Interesting, but not practical

Touchscreens are only useful when they are on handheld devices. For your average home computer, they make no real sense. For one thing, a desktop pc will always have it's screen perpendicular to the hands natural orientation. That creates unnecessary strain. Another thing is that touching doesn't work well with the office metaphor to which most os, including linux, adhere. The ideal touch interface would have a flat screen embedded face up or maybe at a 35 angle in a table. It could have a square section representing your out/in box, a list of icons on the side representing such things as calendar or notes, etc. Think how easy it would be to have ebooks or architectural schematics on an entire desktop. Of course this would probably require some sort of cheap e-paper, but I think the possibilities are endless.

Interfaces are still inadequate

"Historically, the lack of friendly interfaces has been an obstacle to making Linux a commercially viable product for end users, but with available GUIs, that's yesterday's news"

It might be yesterday's news, but that isn't to say that it's less current today. Try making sense of the clipboard in apps on the linux platform:

First test:
- copy text containing 'Windows characters' (eg: stupid quotation marks - 'long' dash)
- try to paste into gnome-terminal
-> does nothing, which would be even worse for people who don't understand the issues around Windows characters (why can't it just filter the characters?)

Second test:
- copy text in gnome-terminal or gedit
- close the window
- try pasting somewhere
-> doesn't work (the clipboard data has disappeared)

They're just off-the-cuff examples of usability problems in a linux platform, and they are neither user- nor idiot-friendly. I'm on my gentoo workstation at work at the moment but am pretty sure Badger suffers identical problems.

Re:Touchscreens holding Linux back?

[__aaclcg7560]

The problem is that user gets a headless linux server and doesn't know how SSH into the box from another machine to use the PINE email client. Presto! A touchscreen LCD solves the problem. It's what known as an IBM solution. :P

Dude, when you're using Anti-Slash's Database Tool to rip comments, please remember to strip the second layer of [link references]. Otherwise everybody notices that you're plagiarizing and you ruin the game.

Hint: hit the "HTML" link on the right side to get text you can copy & paste easily. Just paste it in, post in mode "HTML Formatted", and you're good to go and you've avoided this problem.

Also note that you can "lock out" comments if you're logged in to Anti-Slash, so people can't just search the DB for Qtopia to see where you copied your comment from. (In this case, it wouldn't have helped, since I Googled first.)

Thanks for trying!
