Introduction
There are many occasions where casting the viewable contents of HMT-1 to a larger audience
is required. This is done using a technique called Screen Casting, where all audio and video
from HMT-1 is passed wirelessly to a large screen TV or projector.
The software for screen casting is built into HMT-1, but by default is switched off.
In addition, a special hardware dongle is required to receive the wireless audio and visual data
from HMT-1 and turn it into an HDMI signal suitable for TV or projector.

Hardware Requirements
1. The recommended hardware dongle for screen casting is the ScreenBeam Mini2 from
ActionTec. It retails around $40-$60, and is available from Amazon.com here:

2. It is also recommended to purchase a female-to-female HDMI adaptor. Many conference
rooms only offer a male HDMI cable into their AV system, so the adaptor is an essential
piece of the toolkit for those occasions.
There are many adaptors on Amazon all less than $10. Here is one such item:

Software Setup
For first time use, the Casting software already built into HMT-1 will need to be turned on and
configured.
Step 1: Go to Android Settings
Either say “My Controls” followed by “More
Settings”, or go to “My Programs” and then
select “Settings”.
Step 2: Enable WIFI
Go to “WIFI” and the say “Off” to turn on the
WIFI network system
You don’t have to join a network, but just
have to ensure WIFI is turned on
Step 3: Go to Display menu
Say “Navigate Back” to get out of WIFI
section and then say “Display” to go to
display menu
Step 4: Go to Cast menu
The Cast menu is located at the bottom of
the Display menu screen. Say “Page Down”
to see it, then say “Cast”

Step 5: Enable Casting
This is hidden in the “:” menu, top right of
screen. Say “Select Item 2” to show this
menu.
Then say ‘enable wireless display’ to turn on
the wireless casting feature
Step 6: Link up to the ScreenBeam device
Now the wireless display has been enabled,
the list of nearby dongles should appear.
Select the ScreenBeam device, usually
prefixed with the term ‘SBWD xxxx’.
To do this say ‘select item 3’ corresponding
to the device you want to select.
HMT-1 will try to connect. Once connected
the HMT-1 display will indicate the connect
status. Also all audio will now be directed to
the TV. HMT-1 will no longer ‘chirp’ when you
issue voice commands.

Runtime Use
Once the wireless dongle has been connected, all video and audio will be visible on the TV or
projector device, in very close to real-time.
It will be apparent to the HMT-1 wearer that the connection is active due to lack of audio
through the HMT-1 speaker. All audio is redirected to the TV.
If the connection breaks for any reason, HMT-1 will automatically try to re-establish the
connection.
Rebooting the device will also cause HMT-1 to auto-connect to this dongle.

Notes
•
Once the initial pairing has been completed, HMT-1 will continuously try to connect to the
dongle
•
WIFI casting can be a heavy drain on battery life!
•
To disable Wireless Casting, go to Step 5 in the setup list, and then select ‘enable wireless
display’ to unselect the option.
•
HMDI cable length between the ScreenBeam dongle and the TV input is usually limited to
less than 50ft with standard HDMI cable.
•
Longer lengths have been achieved using an HDMI-to-CAT5 convertor. In this instance, a
short HDMI cable is routed into a long length of CAT5 ethernet cable (we have successfully
run 300ft of cable) and the CAT5 is converted back to HDMI and then into a TV.
