10. Detailed Description
Wonderful for therapy, education and entertainment for children, adults and older adults.
Combines the responsiveness and activity opportunities of interactive projection with the palpable
experience of sand for a highly multi-sensory experience. Interactive augmented reality allows
users to transform sand into the earth’s surface with lakes, mountains, volcanoes and valleys; to
dig up dinosaur fossils; to play ‘football’ and much, much more. Loose materials such as sand
allow imaginative play and creative activity whilst providing tactile sensations that promote fine
motor skills, tactile perception and hand-eye coordination. White frame as standard - other
colours available upon request.
Includes:
• Table frame with metal reservoir for sand, laminated board top (to turn this into an
interactive table), additional legs (to adjust the height) and projector arm
• Projector with 3D depth sensor, USB and HDMI cables
• Marble sand (recommended by therapists for motor skills development as especially mouldable)
• 94 wooden sensor objects – for the Interactive table games
• Wireless keyboard
• Software featuring activities for sand and table
Assembly and set up required on receipt - 2 people required. Telescopic legs are available
separately for the Large option for wheelchair users - contact us for more information.
This is flexible, and uses cognitive skills and motor skills. Fun –using this product is enjoyable
and encourages working collaboratively.
Sand Activities
Sapper
Level the sand at the start of this activity - areas that need
flattening are indicated by blue light. Find a chest and
keep digging around it and it will jiggle then open.
However, avoid the traps and explosive mines. This
activity requires patience, attention and encourages hand-
eye co-ordination. Moving the sand on this activity is
quite challenging but also calming. The user regulates the
pressure exerted. There are 7 levels of difficulty in this
activity. Up to 6 users can play at once to develop
teamwork.
Fossil
Carefully excavate the bones. Once the bones glow red,
the user must be very gentle. This activity is based on
memory and using care. Bones will crack if the user digs
dip too deep or too quickly. This activity has various
difficulty level and may be useful for those who are
hyperactive.

Water
This is a no-fail, non goal-orientated activity. Users can make islands, make water splash and
ripple. Good for fine motor control, gross motor skills, story-telling and imaginative play. To
encourage decision-making, users could use suitable toys such as plastic figures and they
could be asked to keep a person/creature on land stay dry and safe. This activity is effective
when balls are thrown into the ‘water’ to encourage further motor skills.
Volcano
This educational activity is about 3D landscape modelling and
visualization. Lower landscape appears as underground water whilst
higher landscape appears as hills/mountains. Build the volcano till
black at the top then make a hole in the top till it goes white. Up to 5
volcanoes can be made at one time in the standard tray. This is a
basic activity but it is very engaging. The activity can build in
complexity according to instructions given to the user e.g. place a toy
house/person in the tray and user directs lava away from it/him.
Sand ball
For 2 to 4 players. Aim to score in the opponent’s goal by
moving the sand to move the ball forward. This activity is
good for problem-solving and developing hand-eye co-
ordination.
Hedgehog
Help hedgehog get to bunny’s birthday party.
Hedgehog must avoid the balloons as his spikes will
burst them. Users must dig out a groove for a path
first and gently push the sand under the hedgehog to
get him to the party. The sand and users’ hands don’t
pop the balloons –only the hedgehog can. This
activity has 7 difficulty levels and has sound effects.

Table Activities
Activities using the white laminated lid over the sand reservoir
Alphabet
Spell a word correctly using the wooden sensor objects and a
corresponding image/animation of this will be visible –CAT, DOG,
HOUSE. This is suitable for early spelling skills.
The cat and dog can also be heard. Theses auditory cues help with the
association of word and object e.g. cat meowing. For children and for
those with learning difficulties, a visual product like this in a darkened
room can help those with attention deficit disorders.
Castle
Place the wooden sensor objects to defend the castle from attack.
A blue triangle causes ice; a pink flower causes fire (although the fire doesn’t melt the ice).
Use these to defend the castle against the monsters. The monsters are abstract so there is no
requirement to recognise these. This activity works on hand-eye co-ordination and cognitive
skills –there is judgement, reasoning, a rationale behind where you move the pieces to. The
castle isn’t destroyed if the monsters reach it, so this is a no-fail activity.
City
Place the wooden sensor objects to create transport
networks. Each wooden sensor object represents a mode
of transport –road, air, railway. The display reacts to
intersecting transport modes, such as building bridges if
roads intersect. The vehicles change according to the size
of the route e.g. the helicopter becomes a jumbo jet.
Users could put their own objects on the top (e.g. bean
bags, toy railway bridges) and supervisors could ask them
to create a road, train track etc. around it i.e. set users
tasks. This activity is good for cognitive skills, orientation,
topography (planning), problem-solving, hand-eye co-
ordination, development of perceptual skills.

13. Installation
Preparation
1. Two people will be required to install this product. Installation requires a good level
of computer skills competency.
2. Consider the following when choosing the indoor location of your Interactive
Projection Sand Box:
Access to a plug. The power cord needs to be straight (no bends/kinks) and in a location
where it will not be trodden on or where there is a risk of objects being placed on it.
Install on a flat, stable surface in a dry environment. Do not install or operate this
product at temperatures below +5˚C or above +55˚C.
Do not install or use this product near sources of heat such as radiators, stoves,
flammable objects (e.g. candles, fireplaces etc.) or any other appliances (e.g. amplifiers)
that produce heat.
Avoid areas that may be exposed to vibration.
The size of the unit –allow room for movement around it also
The Interactive Projection Sand Box is to be used in dry environments only
This product is most visually effective in a darkened environment, not in bright
lighting conditions
The product requires re-calibration if it is to be moved to another location with
different lighting levels
Assembly
Unpack the sand reservoir. Turn inside (under the reservoir) and lock all 4 casters, as
shown below, to the right.
Unpack and install the telescopic stand strictly vertically to the
sand reservoir using M5 machine screws.
Install the lower telescopic stand to the bottom of the reservoir 4+4 screws on each side.

Connect the telescopic stand –upper and lower body 3+3 on each side, 4 on back side.
The distance between top of the reservoir and the sensor must be 1.38m for the
Standard Sand Box (2.02m for the Large Sand Box).
Secure the Projection block on top of the stand with 4 M5 screws on each corner.
Plug in the power cable and ethernet cable.
Plug in the external power cable to the telescopic stand lower back socket.
If the temperature difference inside and outside the room is more than 15° or the

shipment was carried out in the winter, it is necessary to leave the System in a warm
room for 3-4 hours before switching on.
Switching on and Operation
1. Plug in the power cord. Activate the projector with the remote control.
2. To enable the built-in computer, use the start button on second remote control.
When you click on it, the built-in computer will start. A projection with a desktop
with shortcuts to preinstalled programs will appear on the sand.
3. To work with the system, you need to use the wireless keyboard (connected to the
Monoblock). In addition, we are offering double USB hub to connect to Monoblock
when needed:
Turn on the wireless keyboard.
4. Important! The use of any unlicensed SOFTWARE will invalidate the user warranty.
5. In the case that the screen resolution is not automatically set –use the remote
control to turn off the computer and unplug the power cord for 10 seconds.
6. Before filling the tank with sand, adjust the projection, following the necessary steps:
Set the colour mode to sRGB –path Menu, image, color mode.
Set Signal Aspect to Full mode –path Menu, Signal, Aspect, Full.

Change the trapezoidal distortion of each angle of the projection, using the
remote control of the projector (Menu, Setting, Key Stone, Quick corners) Set
each angle to its max to its relative corners.
Set the Mirror of the Projection block to the best position to cover the entire
reservoir with the projection light (projection will most certainly come outside
the reservoir; we need to make sure there is no unlit part of the reservoir)
Use the same screws to fix the mirror tight, on both sides.

After the Mirror is set –the exact projection adjustment is needed. Using same
path as before (Menu, Setting, Key Stone, Quick corners) achieve a uniform
horizontal light spot relative to the sides of the sand tank. The projection light
spot should be projected onto the sides of the tank with sand approximately ¾
of the height. Pay attention to the combination of the horizon of the light spot
on the sides and in the corners of the tank. With the exception of the sides of
the tank with the telescopic stand of the projection.
The light spot is projected vertically onto the side of the projector rack tank. These
settings affect the uniformity of the projection spot and exclude non-illuminated
(shaded) areas in the working area of the sand tank.
After adjusting all 4 corners, the final image must look like that shown below.

There is a similar projection dark line on 3 sides, except the side of the tank
with the telescopic stand where the image barely appears on top of it.
7. The selection of programs (modes) is carried out by launching the corresponding
application on the desktop of the computer (using the keyboard).
8. IMPORTANT! Be sure to wait for 2 minutes after turning off the PC and Projection
System. This is necessary to cool the projector lamp. Disconnect the System from the
power supply.
9. IMPORTANT! For safety reasons, it is ALWAYS necessary to disconnect the System
from the ~220v network when it is not in use.
10. IMPORTANT! To extend the life of the System never unplug it from the outlet,
without first making sure that it was correctly turned off.
11. If any failure occurs during the operation of the PC or projector, it is necessary to
disconnect the System from the power supply, wait for 10 minutes and turn it on
again, following this manual. If the operating System does not load, contact the

Manufacturer's technical service.
