Analysis of the research
-where are we looking in the world? How people use MP3 players, how people use their phones and the gestures they use. We also looked at ASL to see what kind of hand gestures already exist.
-why? ASL because it is already a language made out of gestures, and we looked at ipod's and cellphones because that is part of the cultural and social context were looking at.
-what did or can we learn? We learned that ASL has many ways of signing things, that have gestures that relate to what the word means. People like to use just their hands and palms for the gestures. Phones and ipods fit into your palm and people like to use their fingers to work the device so people are used to hand gestures.
-how would classify persona and scenarios that were found?
Phones and ipods are used by everyone these days in everyday contexts. Even people who are not technologically savvy know the general concepts and gestures needed to make the device work.

Our Getures
[play, stop, forward, back, volume up, volume down, mute]
-function: It's all within the palm of the hand, so for play we have a pointed index finger that circles twice, and then for stop we had an idea but then with typical hand activity one would stop your player when you didn't want to the player to stop, so for stop we came up a 2 step motion. To raise and lower the volume one scrolls finger in palm of left hand up or down. To go forward or back one has fingers go from left to right for forward and right to left into the palm of the opposite hand. For mute close the left hand fingers to thumb.
-symbolic? For some of the gestures the scrolling motion reflects the motion of the volume going up and volume being lowered, the play gesture reflects a "com'on" kind of motion. The mute hand gesture reflects the sign language motion for shut down, to close your hand shows that something has stopped, in this instance the sound.
-what persona/scenarios could be used? A person is running, they don't have to press any buttons while running in order to adjust the music on their player, they can quickly make the gestures while moving and it requires less focus and energy than extravagant movements. While riding a bike you don't have to put yourself into danger by fumbling around with an MP3 player.
-how to demonstrate/visualize gestures effectively?(how do u produce something that people can know the gestures, how do u visualize it?)
