Multi-touch displays behave in the same way as traditional touch-screens, however a multi-touch system has multiple touch point recognition. This allows two-handed (or multi-fingered) gesturing and operation by multiple users — at the same time.
HDi displays use IR recognition technology. Imagine an invisible infra-red grid overlaying the display — anywhere an object, finger or stylus enters the grid is picked up by the crossbeams and recognised as a touch point. Movement is tracked in real-time by crossing the fine-tuned beams.
Some basic differences between the models can be: Size, Display resolution, Display type, Available IO ports, OPS capability, Refresh rate, Contrast, Frame and Warranty. It’s a good idea to use the technical data sheets to compare the various models. If you’re having trouble then we can also assist you find the right device to suit your needs.
Our HDi edge series multi-touch displays offer up to 20 points of touch and our HDi PCAP series displays have up to 60 points.
The main differences between an interactive whiteboard and multi touch screen are that the multi touch screens cannot be written on with a whiteboard marker. There are also less maintenance costs with a multi touch screen because they do not incorporate filters that need to be cleaned or lamps that need to be replaced compared to a data projector required for an interactive whiteboard. Additionally, interactive whiteboards provide a more economical solution initially compared to the multi touch screen and also offer larger screen sizes.
Our Interactive Whiteboards can be used with your finger or a stylus. No special pens are required so there is nothing to lose or replace. No batteries are required for the stylus.
To connect your interactive board to your computer, there are two cables that are required, a VGA cable and a USB cable. The VGA cable supplies the video signal to the projector and the USB cable provides the interactivity connection between the interactive whiteboard and the computer. Plug one end of the VGA cable into the wall point and the other into the computer. Plug the small end of the USB cable into the wall point and the other (flat) end of the USB into your computer. Note: The instructions above assume that a wall plate is being used for the installation; some installations may use a HDMI cable instead of a VGA cable.
To connect your multi touch screen to your computer, there are two cables that are required, a VGA cable and a USB cable. The VGA cable supplies the video signal to the screen and the USB cable provides the interactivity connection between the multi touch screen and the computer. Plug one end of the VGA cable into the VGA socket on the rear panel of the screen and the other into the computer. Plug the small end of the USB cable into the socket labelled Touch USB on the rear panel of the screen and the other (flat) end of the USB into your computer. Note: Some installations may use a HDMI cable instead of a VGA cable, in this instance, plug into the HDMI socket on the rear panel instead.
To calibrate using a Windows 7+ computer, go to Control Panel and then Hardware and Sound. Under Tablet PC Settings, select Calibrate the screen for pen or touch input. Once Calibrate is selected, depending on your system, you may be asked by the system controller whether you allow the program to make changes to your computer. Select Yes then follow the instructions on the screen. To calibrate using Windows XP or MAC, run the calibration software from the supplied CD that came with the Interactive Whiteboard. Launch the appropriate calibration file and a dialogue box appears giving you the option to Calibrate or Reset. When you select Reset, the board is restored with the default factory calibration condition. Once the Calibration option is selected, the calibration process starts. Follow the on-screen instructions and touch the points indicated on the interactive whiteboard. Ensure that the points are accurately touched as indicated by the Target. Touch and hold the Target until it disappears and the next Target appears. Once all the four Targets are touched, the calibration is complete.
To activate right click, touch the interactive whiteboard with your finger or stylus and hold your touch.
Use the supplied micro-fibre cloth and dampen with water if needed. For stubborn marks — spray Windex onto the micro-fibre cloth first, then wipe the surface. Avoid using any harsh abrasives as these can damage the whiteboard surface.
Although the Interactive Whiteboard is not designed for use with permanent markers, should someone write with one on the board, use a regular dry-erase marker, scribble back and forth over the permanent marker ink and erase. You will see it gradually disappear. Repeat if necessary.
