Because the multi-touch panel of the iPhone and the iPod touch respectively uses a completely different approach than most of the widely adopted resistive touchscreens available in other mobile devices, you need a different kind of stylus. The screen of the iPhone is designed to take input commands only from person’s fingers (or other body parts), but not from a plastic stylus for instance that is normally used in touchscreen devices. In order to do that the screen of the phone has a lot of built in capacitive sensors that detect a difference in the charge of every place the user touches the screen, but in this way the screen is not pressure sensitive. So in order for you to use a stylus in combination with the iPhone you’ll have to use a specially designed “pens” for this type of multi-touch screen.

Until recently it was quite hard and a bit expensive to get such specially designed stylus, but now they are quite widely available and are being produced in big quantities in China. Actually you can even get a pack of two specially designed stylus for iPhone and iPod touch for less that 6 bucks and you get even free shipping for them, a great deal if you ask me. So if you have bigger fingers or longer fingernails and have problems using the touchscreen of the iPhone or your iPod touch music player you can get these “pens” and fix the issue…

The price of a pack of 2 stylus is just $5.77 with free shipping.

The new iPod touch features Apple’s revolutionary multi-touch user interface that enables users to find and enjoy all of their music, videos and more on its gorgeous widescreen display with just the touch of a finger. First introduced on iPhone, the multi-touch interface uses pioneering new software to present the perfect user interface for each application. The iPod touch also includes Wi-Fi wireless networking, the first on any iPod, and three amazing applications that use it – Safari, the most advanced browser on any mobile device, lets users wirelessly view web pages just as they look on their computer, and features Google Search or Yahoo! oneSearch; Apple’s YouTube application lets users wirelessly watch over 10 million free videos from the Internet’s most popular video website; and the new iTunes Wi-Fi Music Store lets users wirelessly browse, preview and buy songs and albums from the most popular online music store in the world.

With its gorgeous 3.5-inch widescreen display, iPod touch is perfect for watching movies and TV shows, as well as viewing photos and album art. iPod touch has a built-in accelerometer that automatically senses when you rotate it into its landscape position. When you’re in music, it automatically switches to Cover Flow so you can browse your music collection by album cover artwork with just a flick of a finger. When in Photos, it automatically displays the photo in its landscape aspect ratio; and when in Safari it displays the web page horizontally. iPod touch also has a built-in ambient light sensor that automatically adjusts the display’s brightness. iPod touch features up to 22 hours of audio playback and up to five hours of video playback.

The iTunes Wi-Fi Music Store lets you browse the iTunes Top Ten lists of songs and albums overall or by genre, check out new releases and “What’s Hot,” or search for your favorite songs, albums or artists. You can preview any song for free, then purchase and download the ones you like directly onto your iPod touch over Wi-Fi. The music you download will be automatically uploaded into your iTunes library the next time you sync your iPod touch with your computer.

With Safari, the most advanced web browser ever on a portable device, you can see web pages the way they were meant to be seen, with the ability to zoom into any webpage with a tap of your finger. The Safari web browser includes built-in Google Search and Yahoo! oneSearch so you can quickly and easily find information you need. iPod touch also includes Apple’s incredible YouTube application that allows you to access, browse and search for millions of free YouTube videos over Wi-Fi.

The 8GB iPod touch model currently is $299 and the 16GB iPod model is $399 and the 32GB version can be bought for $499.

MERL DiamondTouch

Mitsubishi Electric Research Laboratories (MERL) DiamondTouch table is the world’s first multi-user touch technology, allowing multiple people to work simultaneously, and the system knows who is who. DiamondTouch also supports rich gesture inputs, and it is debris tolerant (meaning that you can put your coffee cup on the table – no problem). This makes DiamondTouch a useful tool for supporting small group collaborative activities.

Currently the DiamondTouch table is available commercially only as a developer’s kit and includes: a selection of demonstration applications; a mouse emulator with onscreen keyboard to support common Windows applications; and a Software Developer’s Kit allowing the development of new software applications that support gesture inputs and multiple simultaneous users.

What is the objective

Computers are good at facilitating collaboration between people in remote locations. However, when people are in the same place at the same time, computers tend to get in the way. DiamondTouch supports small group collaboration by providing a display interface that allows users to maintain eye contact while interacting with the display simultaneously (i.e., without having to take turns). DiamondTouch was first created in 2001 as an experimental multi-user interface device. Over the past few years, MERL has manufactured about 100 DiamondTouch tables, lending them to universities and research organizations around the world.

Technical Discussion

DiamondTouch is front-projected and uses an array of antennas embedded in the touch surface. Each antenna transmits a unique signal. Each user has a separate receiver, connected to the user capacitively, typically through the user’s chair. When a user touches the surface, antennas near the touch point couple an extremely small amount of signal through the user’s body and to the receiver. This unique touch technology supports multiple touches by a single user (e.g., two handed touch gestures) and distinguishes between simultaneous inputs from multiple users. DiamondTouch tables are available in two sizes (32″ diagonal and 42″ diagonal display), while custom sizes and shapes are available on spec.

DiamondTouch Features
– Multiple simultaneous users
– Ability to distinguish who is who
– Rich gesture inputs
– Operation with objects on table
– Choice of 32″ or 42″ diagonal surface
– Control of any Windows software using mouse emulator
– Tools for developers to write multi-user, gesture-activated applications
with SDK and open API

Developer???‚?„?s Kit includes
The developer’s kit includes the DiamondTouch hardware and drivers, plus a software developer’s kit (SDK) that supports application development in Java, C, C++, .NET and ActiveX. We will include a few demonstration applications, as well as a Windows mouse emulator or DTmouse. With DTmouse and access to a pop-up on-screen keyboard, you can drive Windows applications out of the box. If you want multi-user capabilities or gesture inputs, you can use the SDK to develop application software. The DiamondTouch developer’s kit does not include a projector – you can use your own or you can purchase one from us. You will need to have the projection image aimed down onto the DiamondTouch table. Here again, you can purchase a floor stand and mounting bracket, or you can use something of your own design.

Pricing of the DiamondTouch
– DT81 (32″) developer’s kit* – $9,500

– DT107 (42″) developer’s kit* – $12,500
– Mitsubishi XD60U DLP projector – $2,300
– Mitsubishi XD490U DLP projector – $3,400
* There is no DLP projector included in the kits!
