The Apple QuickTime player is required to view the Virtual Tour.
There are two ways to download the Apple QuickTime Player from the
Apple website. If you are behind a government or corporate firewall,
then it is best to download the Standalone Installer (about
an 11MB download). If you use the normal partial download, the firewall
may stop your PC from downloading all the required parts of the
program.
If you are using a modem then it is best to use the normal QuickTime
Player download. However, be warned that this will take some time
to download, possibly up to 15 minutes, but you only have to do
it once. The QuickTime Player is used on a broad range of websites,
so it is a useful applet to have installed on your computer.
If you don't want to wait for the download, the QuickTime Player
can often be installed from the CD found on the front on many computer
magazines.
The tour utilises QuickTime to view the virtual tour
images. Each image will take from 45 seconds - 1 minute to download
on a normal modem. Each virtual tour has a small set of buttons
at the bottom of each of the windows. These buttons are shown below:
The Controller Bar and keyboard shortcuts: (left to right)
Use
the minus sign to Zoom Out - you can also use the "Ctrl"
key Use
the plus sign to Zoom In - you can also use the "Shift"
key Use
the arrow to show the hotspots, which access information pages or
take you to another image in the tour
The text displayed in the Controller bar is the name of the hotspot
that the cursor is currently hovering over. Hotspots that opens
pages of information about the Healthy Home have Information at
the start of the name, while hotspots that will take you to another
virtual tour image have the word Link.
Controlling the interface
Place the mouse cursor in the image and hold down the mouse
button. The cursor changes from a bull's eye icon to an arrow
icon that points in the direction you move the mouse. The image
scrolls in the direction you are moving the cursor. The further
you move the cursor from the centre of the image, the faster the
image scrolls. Once the rotation stops you have reached the edge
of the image.
You can also move the image around using the arrow keys on the
keyboard, i.e. left and right, up and down. The image scrolls
as if you were turning around using the left or right arrow buttons
or looking up and down using the up and down arrow buttons.
You can zoom in and out of the image by pressing the Zoom In
and Zoom Out buttons on the Controller bar. Also, pressing the
"Shift" key will zoom in and pressing the "Ctrl"
key will zoom out.
Revealing the hotspots
By showing the hotspots (as seen below) it can be easier for novice
users to navigate through the various links in the virtual tour.
The masks on the image below are all hotspots.
The hotspots link to either information about the object you are
looking at, e.g. the louvres, or another viewpoint, called a node,
in the tour. To turn the hotspot on, click on the arrow button in
the Controller bar of the QuickTime virtual tour window. To turn
the hotspots off, click on the arrow button again.
