Brainstorm

1. Use topography, e.g.

   North-South as axis to go along, West-East as left/right panning

2. How to do importance weighting?

   by population - to amplitude? -> no, that occludes others, best to duration.

   first data value to display: wealth , i.e. GDP_per_person

3. How to roganize playing in time?

   a) One country-> one event, i.e. go over (sorted) lists?

   b) Interactive ? i.e. query countries individually?

   c) one country is center, others by proximity?

   d) regions by speakers -> installation mode; time as the interaction variable.

   e) select subgroups by one variable; e.g. only play the poorest 20% of a region, or the middle, or the top 20% (a sliding selection window).

Experiments

Intentionally go slow, show and test every change of code

Weighting of population by duration

Groups by region,

Spatialisation,

What Next?

• use mapped population weight for duration and waittime (1 min) * interactive selection by one variable is (half an hour)
• better sound, more dimensions

Evaluation

• interaction is important and is realized here by the way that the listener can move
• regional comparisons are possible
• more tuning necessary
