The figure below shows the USB Snakescope camera. It is powered by connecting it to the USB
port of a computer. It has a semi-flexible tube with a webcam at the tip and transmits an image
to the screen of the computer. The camera can be used to locate items in hard-to-reach places
such as behind heavy furniture or underneath a cupboard. There are two LEDs which illuminate
the space being inspected and a clip-on magnetic attachment enabling the user to retrieve
metallic items easily.

CASE STUDY
The figure below shows a set of plastic cutlery (knife, fork and spoon) designed by Julia
Carlson and marketed under the title of “Greenware”. The cutlery is made from biodegradable
plastic derived from soy bean. Biodegradable means that the plastic is able to be broken down
by the activities of living organisms and is therefore unlikely to persist in the environment at the
end of its life cycle. However, the cutlery is not designed to be disposable and the handle mould
for each piece is the same.

Please read the case study carefully and answer the question.
Figure 1 and Figure 2 show the Ultracane manufactured by Sound Foresight Ltd (UK). It was
developed for use by blind and partially-sighted people. In development it was called the “Bat
cane” as it bounces ultrasound off objects and feeds back information to the cane. The feedback
is not audible but tactile so it does not interfere with other hazard information. Buttons on the
cane indicate the direction of the object and the intensity of the vibration lets the user know how
far away the object is. The Ultracane is manufactured from a lightweight composite material
and is available in 10 different lengths.
