Although standard voice call has the advantage of being efficient and quick because of its real-time communication, it still has a tendency to be replaced by other communication services such as SMS or other social networks, which use message to communicate rather than voice.

mind map -

This project aims to redefine the basic Telephony Function for iOS system (rather than design a new app), and the functions it redefined are presented as follows.

Improved Functions 1 Users can set Personal Information as well as its Visible Range in settings.

(All information will be imported into an intelligent number library after verified, which can improve user experience.)

2 According to When and Where, users can set Accessible Calls, in order to avoid unnecessary disturbance.

3 Users can preset both Text and Voice Replies to contacts or strangers, and then select them directly when receiving calls.

user test -

1.Set visible permissions 2.Block the threat level of nuisance calls 3.Set a schedule for Do Not Disturb 4. Customize ringtones and vibration patterns 5. Set and save replied texts 6. Record and save replied voice

Tester Menghan Shi Standard Voice Calling Seldom Use Testing Problems Cannot understand some settings on "Call Blocker" interface Confused with the selecting of "Not Disturbing Period"

Tester Siyu Wu Standard Voice Calling Often Use Testing Problems Confused with how to Customize a piece of Music for "Ringtone" Misunderstand the Recording Process of "Replied Voice"

Conclusion About the user test, I set up 6 tasks according to the main functions and invited 5 people to participate in.

During the testing process, all 5 testers completed the tasks smoothly. But some of them feel confused about certain settings; therefore, I made some changes to these interfaces.

TELEPHONY REDEFINED Conclusion This project contributes to redefining the phone’s original function —— Telephony Function. It has an intelligent number library to provide multiple solutions when users receiving unwelcome calls. It also considered various call situation and added several modes to improve the user experience.

This redefined phone system can attract more people to use or reuse the telephony function, get them back to the original point and help them find the original meaning of the phone.
