Yi-Jen LaiArthur LiuAndrew Puchle
Problem SpaceContext
The purpose and overall goal of this device is to improve the patient dentist relationship by localizing a patient’s information in one place.
The device is designed for foreign visitors. The device will help people in their daily lives
because it will automatically store demographic and medical information, such as x-ray film, reducing appointment times and it will provide information designed to encourage more healthful decisions concerning dental hygiene and maintenance.
Problem SpaceUse
P.D.A is a portable, easy to transport device that uses a projectable GUI which allows users to interact in real-time with a virtual interface.
It will be designed as an extension of a central EMR database and will provide easy to use, secure, portable transport and storage of personal dental information
The device will also provide the foreign visitor with pertinent information about local dentists such as specialties, customer complaints, experience, cost, office proximity and educational background.
As a personal gadget the device also constitute as personal dental advisory assistant. It manages the dentist appointments and routine applications of treatment. The device also gives personalized teeth maintenance advices daily to help the carrier keep healthy.
Problem SpaceAssumptions
The dentists will be categorized by specialties. A general dentist will be listed as a general practitioner and all others by their specific area of expertise.
The patient is wishing to minimize the procedures for treatment and also to minimize costs.
The patient will not have extreme visual handicaps such as blindness.
The user should have some basic computer knowledge due to the digital nature of the menu system, but the overall goal is to design the product for novice users as well as computer experts.

Conceptual Model
Based off the ‘Sixth Sense’ from TED Labs at MIT.
Interface is projected from a small, portable projector that can be worn around the neck or carried in one’s pocket.

EVALUATING DESIGNS
Usability Study-Interview
A. Four participants B. Six questions (open-ended
question) Example : While you’re using the
product, do you always know where you are?
Usability Study-Internal Walkthrough
A. One team member
B. Three tasks Example : Using “My Records”
which is under the functionality of “My Mouth” to send your dental records to the dentist.
Assessment of findings
Most of participants thought the device (PDA) makes sense to them and is helpful especially when they face dental care problem, but there still has some points could be improved.
Assessment of findings (Interview)
Pro : All the usability participant know how
to accomplish the task by the way the design team desired
All the usability participant agree that they always know where they are while they are using the product
Assessment of findings (Interview)
Con : Some participants cannot connect
part of the icons with their functionality
most of participants cannot image what difference between the current prototype and the projectable version of the device
Assessment of findings (Internal Walkthrough)
The prototype is not totally interactive, hence it is difficult for participants to clearly understand the whole concept of the device
Although most of participants are international student, they had not undergo the dental issues in the United States yet
How to improve the product with the evaluation finding in the re-design
Reconsider what icons could be accepted and understood with their functionality by most of the users
Enhance the interactive level of the product
Adjust the position of the user to the same spot
