PlayStation Portable
The PlayStation Portable is one of my favorite gadgets. This was my first handheld gaming console I ever owned.
Affordances: This portable system has many affordances to be talked about. Firstly, this system is not only used to play video games, but it can be one of a kind all purpose multimedia player you can play your favorite tunes, movies, and even browse on the web. Secondly, those functions that I mentioned, those functions will correspond efficiently at ease.
Constraint
Physical Constraint: For the physical constraint: The PlayStation Portable have a basic axes of a directional pads, which consist of up, down, left, and right. These directional pads are easy to used to browse the multimedia section. Another physical constraint is the analog control, which is mainly used for games.
Psychological Constraint: This system has a handful of useful symbols to use especially the convention, the normal playback control can be found in the music and video multimedia. The volume controls are easy to use in order to get the level of volume you want.
Mapping
The PlayStation Portableís mapping is similar as the regular PlayStation controllers except the handheld gaming system has the 4.3î LCD screen, and the buttons configuration is the same. Other additional includes wi-fi on the top left side of the system, the 2.0 USB mini port is on the top side, the batter charger slot is on the bottom left, and the headphone slot is on the bottom right. Therefore the mapping of this handheld gaming system is easy to use.
Visibility
In my opinion, the battery indicator on the PlayStation Portable is the best feature and I am glad to have it because it could really tell me exactly when the battery is low. When the green light is blinking, the batter is running low and for red light imply that the battery is receiving the power when it is charging. And lastly, it can tell me when the system is fully charged if there is no light when the system is turned off.

This mp3 player is very small and light, and it is easy to bring and to travel with it.
However, this mp3 player has major flaws in term of its function. The mapping of the buttons is convenient but the affordance on this player is very annoying. The most annoying part is when you have to look for the specific song you want to listen to, and when you found the wrong song, you have to go back from square one to look all over again (e.g. from the artist names" letter "T" jumped back to letter "A").
This mp3 player has another flaws on their affordance. The most annoying part is the volume control, which have two opposite directions as in increase and decrease the volume which okay but the responding is not very good, This is because when I press the volume, sometimes it is not responding to either increase and decrease the volume even though I press for slightly long time while waiting.
The iPod look-alike circle control has a minor problem, there are too small to press, and I always canít get to press the playback button right at the spot. The buttons is very sensitive especially when I kept it in my pocket, and it can accidentally change to unwanted song by accidentally press the playback button with my body.
