Primary: energy conservation
Secondary: speed is related to kinetic energy
Secondary: thermal energy
There are three scenes in Energy Skate Park Basics:
There are two charts, bar and pie, which show the conservation of energy, which are key to the learning outcome. The charts show:
When the simulation is running, the bars / sections of the chart animate to show the conversion of potential to kinetic energy. The pie chart follows the skater, while the bar chart stays in a static location.
Since the two charts are showing the same information but presented in different ways, it may be possible to have a single sonification of the two charts.
The thermal energy can be "thrown out" - this resets the thermal energy to zero, and decreases the total energy by the amount thrown away. After zeroing, thermal energy will continue to accumulate if there is friction. The use case for this isn't very clear but was a user feature request.
Use 4 distinct sounds to the different energy types and total.
Use volume to indicate quantity. Quieter = less, louder = more.
The total energy would be a constant hum in the background that increases or decreases in volume depending on the total energy of the system.
The following sound clip is a rough rendition of a sonification of the bar graph. The funky guitar is potential energy, the deeper bass is kinetic, the bell is thermal energy, and the drum playing throughout represents the total energy.
After the skater has stopped, "return skater" buttons appear. Selecting these buttons return the skater to either the last release point, or to the bottom of the play area.
This allows the user to replay and adjust variables (i.e. friction and mass) and redo an experiment.
These buttons can overlap with elements on the page.
Question: Is it possible to create a "drag and drop" equivalent using native web controls?
Scheme 1: Separate X and Y sliders
Below: When moving the skater around to be positioned, sonification is used to indicate distance from the track below (represented by volume volume), and the elevation of the track (represented by pitch).
Below: This is a special case where the skater is being positioned within a loop.
Haptics and tactile feedback could be useful for navigating, controlling, and understanding the simulation. Possible devices include: game controllers, mobile phones, and wearable vibrating motors. In the sim, tactile feedback could be used for:
Possible implementation could be done using GPII Nexus.
