GR3 - Paper Prototyping
Although we created three different prototypes and tested them all in Round 1, the photographs below show the Address Book prototype specifically, which we chose to focus on for Round 2 after the feedback received from Round 1.

Briefing
Here is the briefing we gave to users: Purpose of application: To connect the elderly with their younger family members
...
explore the food options safely using our menu.
- You are a native English speaker, but you have trouble typing and you are somewhat unfamiliar with using computers.
- Your granddaughter is Lily, a college student in California.
- This is your home computer, and it is the computer you use to go online. Assume webcam and microphone come with the computer, ready to use. Pretend Lily calls you one day and asks you to add her as a contact on ElderConnect so that you can stay in contact and chat sometimes. Scenario Tasks.
- "chicken vegetarian", someone who is a vegetarian, except that you eat chicken.You are also allergic to peanuts
Scenario Tasks
Here are the tasks we gave to users, one after another.Task 1: Lily calls you and asks you to add her as a contact by dialing the number 721-4146.
Task 2: One day later, you want to send Lily a message.

3. You realize today is a special day so you want to eat burgers. Task 3: A few days later, you go on ElderConnect again. You want to call Lily.
Observations from Wednesday's Testing (Round 1)
Total number of users tested: 5 (Address Book: 3, Phone Metaphor: 1, Action wheel: 1)We built and tested all three prototypes to get a more holistic comparison between the three designs.4
User testing descriptions
...
- Phone
- During the add-contact task, users were uncomfortable with the fact that the phone call actually went through to the granddaughter. Some expressed that “Add contact” should feel different from a normal phone call, and should allow them to hit an “OK”-like button to confirm before the request is sent.
- Lacks a “send” button. old dial-tone phones with no numerical feedback do automatically start dialing, but since our display looks like a cell phone that displays numbers, it should be consistent with cell phones having a “Send” button.
- No way to delete one digit at a time. This is poor safety for the elderly who may make errors while entering digits. Having no digit-backspace also threatens efficiency; the user would need to completely start over if he/she makes any mistake.
- Lacks an “end call” button. This was simply an oversight on our part.
- Not a real cell-phone number (only 6-digits long).
- User not sure if * and # keys are necessary since they are never used when dialing a phone number.
- Mail
- Yellow mail icon misconstrued to be a “compose mail” button.
- “You’ve got mail” icon being inside the address book seemed to be inconsistent with the address book metaphor; normal address books don’t have mail-receiving functionality inside. User suggested to put the inbox in a corner of the browser instead rather than associating each mail icon with a particular contact.
- Can’t hear message playback or see previously sent/received messages again.
- Options/Widgets
- No way for grandparent to write an email, yet receives emails from grandchild. Makes user feel somewhat mistreated.
- Doesn’t make sense for “call” and “send voicemail” to be two diverging options. Normally the caller would call and, if the recipient doesn’t answer, the caller would leave a voicemail.
- Call/Send Voicemail screen: user wondered why both options were shown even though the contact was not online.
- Need video vs. audio option
- No way to send a video message.
- User said that it may feel more like an address book if the user can fill in the details right on the book instead of on a popup. So maybe clicking on Add Contact will turn that entry into some text fields.
