Task 1: Ergonomy
Please rearrange the order of the arrows aligned on the bottom so that it's easier for the dancer to perceive the change and adjust their steps. Please use plane coordinate knowledge.)
Task 2: Do you like the music played? If not, please replace it with your favorite song.
Task 3: Use the aluminum folio and Yoga mat to build the dancing mat. Link it up with the computer and the MakeyMakey set.
Programming Details for advanced programmers and learners:
1. （Scratch programming) Clone---The arrows which run upwards are clones of the ones staying on the bottom.
2. (Scratch programming) Random --- A number is picked up from 0 to 4 randomly. If it's 0, another random number will be picked up from 5 to 10. Each chosen number presents a specific arrow(1 to 4) or a combination of two arrows (5 to 10). Arrows will be shot when the corresponding number is picked up (details see in Broadcast).
3. (Scratch programming) Broadcast --- According to the chosen number (from Random operator), a message (to one or two arrows) will be broadcast. Upon receiving a message, an arrow (or two arrows) makes a clone of itself and the clone will move upwards and when it reaches the top bar, it will be deleted.
3. (Mathematics) Combination: Combination of two or more things, in which order does not play a role. e.g in this game, two arrows will shoot at the same time occasionally. The arrow pair is a combination of any of the arrows: Left+Right, Left+Up, ect... Please count how many combinations can be built from four arrows?
4. (Challenge) How often do we get arrow combination? --- In the program mentioned above, from 0 to 4, 0 presents an arrow combination, i.e 20% (out of 5 numbers in total). How can we get more combinations, e.g 30%?
