Quality of Prototype

Our Type of Prototype and its justifications
5
prototype functionality (software)

• The user can now choose the type of food
  they like.
• The function to control the amount of each item
  per order is also available.
• The food ingredients are fully displayed to show
  what each food is made of in order to let the
  user consumes his/her food with comfort.
• The parts that still require more work on are
  the connection between the touch screen device
  and the software system, the connection between
  the users and waiters screen, and the gaming
  option of the user side.
• For the open house, we will show the software
  system on a computer notebook. The touch screen
  device will be connected to another computer
  notebook running touch screen demos that allow
  the user to interact with and have the first hand
  experience of how the final product will work and
  feel like.
• The major bug we have just recently discovered
  is the connection may only be allowed to form
  with the support of Action Script 3.0 which in
  our case we have used the well known Action
  Script 2.0. Further research has already begun to
  investigate the transfer from the older version
  to the newer version.

prototype functionality (Hardware)

• Our hardware is 70 functional.
• The user will be able to interact with the touch
  of their fingers.
• Multi-touch is supported which will enhance
  the gaming experience and a possible multi-view
  or 3D view (VR movie) of the food items in the
  final product.
• All the experience described above will be shown
  through the involvement of the user with the
  interactive demos in the open house.
• The hardware will still require more protection
  development to be able to serve as a regular
  table where the user can eat and drink.

7
prototype integration - hardware and software,
backend system and user interface

• Table constructed according to our plans added
  ideas
• Touchlib interface followed Touchlib
  instruction
• SoftwareFlash used action script 2.0 instead
  of action script 3.0
• Backend(MySQL Database) stopped
• User interface altered slightly into more
  appealing (no classic buttons and plain
  backgrounds

Cognitive Walkthrough

description of the prototype of the system

• In the prototype system, the user is able to
  try out the technology of multi-touch of the
  touch screen. The screen is built with 40 IR LEDs
  with a camera and a projector underneath. The
  projector is used to project the digital menu on
  the screen. The IR LEDs will send out the wave on
  the screen to help the camera detect user's
  action. When the user touches the screen, the
  camera will detect the spot that the user touched
  by checking the interrupted infrared wave. Then
  the camera will send the touching data to the
  computer so that the computer can react to the
  user's action.

description of the task

• Based on our past prototype testing sessions
• The evaluator will be asked to order foods
  according to the instruction.
• Choose item that the evaluator wants to order
• Choose how many the evaluator wants to order
• Pay the bill
• All the tasks above are expected to be doing by
  customer as they normally would.

11
who are our users and what kind of experience and
knowledge they possess

• TeenagersExperience with computer, latest
  gadgets, iPod, digital games
• VegetariansExperience in getting detailed
  descriptions for the food they consume
• Retired peopleExperience with the struggle of
  high tech gizmo, including computer keyboards
