Multitouch
Multitouch is a new type of interaction with a computer.
A multitouch system makes other entry devices like mice or keyboards unnecessary. Applications can be controlled by finger on the screen, similar to using a normal Touchscreen but with much more versatility.
Touchscreen techonology overview
Pictures and images can for example be rotated, moved and enlarged by hand.
The main attraction however is that various actions can be made simultaneously. It is like if several PC- Mice carried out different tasks all at the same time.
Applications can be found in Digital Signage and Game sector applications.
For example in museums Multitouch could be used in Information tables and stands allowing several Visitors to simultaneously access the information portal.
Multitouch 2100 / 2150
The 2100 and 2150 are low profile touch frames (9 mm plus glass) which fits beneath the bezel of a manufacturer's LCD or plasma display from 30" to 120".
Multitouch for smaller displays
The 2100 and 2150 provide a fully integrated solution with all the benefits of NextWindow's optical touch technology:
- Clear glass for maximum image clarity
- Accurate touch sensitivity
- Light touch - no pressure required
- Any touch method can be used - finger, gloved hand or pointer
- Once-only, four-point calibration. No drift
- HID compliant plug-and-play USB connection
- Landscape or portrait orientation
The 2100 and 2150 use the USB plug-and-play drivers inherent in Windows or other operating systems. The simple four-point calibration is required only when the screen is powered up for the first time. The touch screen then provides full mouse functionality to control your interactive software applications.

Dimension
NextWindow 2100 / 2150 Touch Frames are made to fit particular manufacturers' display screens. The touch frame consists of a low-profile aluminium frame permanently bonded to glass.
Some constraints apply in the available dimensions, depending on the aspect ratio. Please quote the overall dimensions (X, Y), and the touch sensitive area dimensions (A, B) required.
Touchscreen Sizes
- Maximum standard display size 67"
Custom sizes available to 120"
- Minimum overall width (X) is 510 mm
Minimum overall height (Y) is 390 mm
- Touchable area horizontal dimension A = X - 40 mm
Touchable area vertical dimension B = Y - 60 mm
- The application design should have an allowance (b) at the top of the screen, where touch sensitivity is undefined. The undefined touch zone and hence the height of the touch sensitive area (B) depends on the size of the screen as follows:
Screen size b
Less than 46"
b = 15 to 20 mm
46" to 57"
b = 20 to 25 mm
Greater than 57"
b = 25 to 30 mm
Glass Options
4 mm glass recommended for screens smaller than 32"
6 mm glass recommended for screens larger than 32"
Glass types:
S Standard
L laminated
T Toughened
Note: Glass of 3 mm or less cannot be toughened.
