Introducing Light Touch™
Light Touch™ is an interactive projector that instantly transforms any flat surface into
a touch screen. It projects a full-colour image down onto any flat surface and turns it
into a virtual touch-screen.
Light Touch™ is an application platform with onboard processor, running Microsoft
WinCE 6 R3 operating system. It supports applications written in Adobe Flash Lite 3.1
or Microsoft .NET CF 3.5. Light Touch has wireless networking capability and is
ideally suited to running applications that connect to the internet or cloud-based
servers.
Light Touch model LT1021FC is supplied in a plastic outer shell, designed for
standalone operation.

The Basics
Getting Started
1. Remove from packaging
Check package contents against list on page 3.
2. Place unit upright on flat surface
Place the unit on a flat, level surface. For uniform results, a matte white
surface is recommended.
3. Press the button on top of the unit
This will turn on the unit. A blue logo will be projected for a few seconds
whilst the software loads. Light Touch™ will display a carousel menu which
provides access to a selection of preloaded demonstration applications.
4. Touch the projected image to interact
The menu can be navigated by touching the projected image with a finger
and using standard actions such as swipe and click. A touch is registered
when the finger lifts up from the projection surface, and not when the finger
is pressed down.
Demonstration Applications
The Light Touch LT1021 unit comes preloaded with a number of
demonstration applications, which can be accessed via the carousel. A
category can be selected by a single “click” on any visible icon.
Figure 2 – Screenshot of carousel menu
The pre-loaded applications are provided for demonstration purposes
only. Please contact Light Blue Optics for further information if required,
including enquiries about obtaining permission to use part or all of one of
these applications in a commercial product.
For information on creating applications for Light Touch, see the separate

USB Mode
Light Touch can be connected to a host machine via a USB cable that plugs
into the USB Micro-B port. The USB Mode control panel can be accessed
from the ‘Settings’ menu:
Figure 14 – Screenshot of ‘USB Mode’ icon within ‘Settings’ menu
The default USB mode is ‘ActiveSync’ mode, which allows Light Touch to be
controlled from a Microsoft Windows PC. Further details are available in the
separate ‘Application Guide’ document.
In order to connect using USB ActiveSync mode, a device driver is needed
for the host PC. Instruction relating to the installation and use of these drivers
is contained in the appendices of this document.
Light Touch also supports ‘USB Mass Storage’ mode, which allows Light
Touch to appear as an external drive to a host PC or Mac.
Mass storage mode supports a higher transfer rate and the ability to connect
without using a device driver. However, whilst Light Touch is connected as a
mass storage device, it cannot access its own file system.
The main screen of the USB Mode control panel allows the connection type
to be selected as shown below.
Figure 15 – Screenshot of selecting USB mode

bbb
Light Touch LT1020 – User Guide v1.1 – Application Release C1.0.0 | Page 15
Light Touch LT1021 Series – User Guide v2.1 | Page 15
There are two different mass storage modes because Light Touch contains
two separate memories that are accessible to the user. The ‘internal’ Flash
memory has a capacity of 2GB and is present at all times. The ‘micro-SD’
Flash memory is an optional memory card that may be fitted into the device
via the external micro-SD card slot.1
If mass-storage (micro-SD) mode is selected, the user will first be prompted
to make sure that a micro-SD card is inserted.
Figure 16 – Screenshot of prompt to check micro-SD card inserted
When Light Touch is put into mass storage mode, the following screen will
be displayed for the duration of the transaction.
Figure 17 – Screenshot of mass storage mode message
When a USB cable is connected, the appropriate memory within Light Touch
will appear as a network drive on the host machine. Once any file transfers
have completed, Light Touch should be restarted using the power button. On
power-up, Light Touch will return to ‘ActiveSync’ mode.
1Note that the external micro-SD card slot is only accessible by removing the back
panel of the outer plastic cover. To remove the cover, first remove the screw at the
bottom of the back panel and then lift off the panel, starting from the bottom.

Light Touch unit, as this can cause interference
with the touch system.
5) Lift the unit and check that the micro-switch is
free on the bottom and can be depressed.
Replace the unit and recheck.
6) If touch is still not functioning, turn the unit off
and restart.
ActiveSync will not connect to
the unit
1) Reconnect the USB cable. Wait for ActiveSync
to attempt connection before trying again.
2) Turn off and then restart the unit and attempt
to reconnect
3) If this does not work, restart the PC.
A white screen is displayed or
a message box appears and
the unit becomes unresponsive
