A simple addition to the GUI would reduce the need to consult a user's manual, and thus the
learning curve for this device. By providing a visible mapping between the GUI indicators and the
joypad, the user will not need to recall from memory the shortcuts represented by each direction of
the joypad. The cost of implementing the GUI modifications is about $160
3.3. Keypad - Elevated and Separated Keys
In order to perform fast-paced dialling/texting, a user relies heavily on their tactile sense in order to
find and locate the correct key to press. For example, a skilled computer user rarely looks down on
the keyboard when typing; he or she relies on the fact that the rough location of the key is known
and the key can be located by the contours of the key (ie. It "feels" like a key that can be pressed).
The keys on the LG Shine TU-720 are completely flat and thus make it difficult for a user who is more
accustomed to a computer keyboard to identify a "pressable" key. To take advantage of this positive
transfer, a possible solution is to elevate and separate each of the keys, making each key
independent. Furthermore, each key can be made slightly concaved to further enhance the
"pressable" attribute. An example of this keypad is that of the LG KE800 Chocolate.
The estimated cost of switching to this alternative keypad would not be significant due to the fact
that LG has already designed a similar keypad such as the one above.

The estimated cost can be calculated by multiplying the contractor hourly rate ($40) by the estimated number of
work hours (4 hours) (Source: http://www.spiritsoftworks.com/resources/2004_salary_survey.pdf)
