Web-based Voice Communication Tool for Groups: YackPack
YackPack provides a simple audio platform that provides any group a natural and effective method to communicate in a private space on the Internet. With YackPack users can leave asynchronous voice messages and talk in real time with a group. Through the richness of audio, YackPack delivers the return to emotional connections with the people that matter most wherever they live, whatever their language or age, and whenever they want to listen.
YackPack was developed by a start-up company in California. I was responsible for all of YackPack’ s interface design from the very beginning.

Easy to understand buttons Image of buttons

I paid attention to button design when I created the YackPack interface, version 2.0.
To use YackPack, users have to understand what they are doing and what

they can do as next steps. This interface provides all the information users need by using four buttons.
I designed the buttons to be simple and easily understood.
