Personal all-around activity tracker:

Wondering if how can I improve myself, or was my day even productive, or what can be changed. Ofc, everything for self starts from self core, from mental to physical health, to health of surroundings, all with action and interaction, affects the existence experience state and its health. And so , the idea of a tracker which can record all activities is born. An activity tracker that can log (and will be processed just like my brain processes but to offload processing so mind can be free), log activities such as : Eat, brush, work on <topic>, action movement took, state updated around surroundings, all things included, nothing private, so scientifically accurate.

Seems like my existence creates 4D impact overall, and I’m existing in adjacent or with other 4D impact creating dynamic systems or beings. When two people interact, their combined interaction and flow is very much different than just one.
For that we can look at simulation of 1 person in a box: a room where sufficient food and survival amenities resources services are there. Evolution of macro action is only possible from person, but nano level action in digital circuits electricity, waves of EM flowing, and sound is just going as usual. So entity capable of making change in surrounding is the person itself, and can be other external drivers which can be almost nothing at calm places, but can be chaotic in other places.

Now we imagine a combined two person system, where interactions are between person-person and person-surrounding. And depending on cognitive architecture along with physical architecture of person, the system will evolve.

Such systems can go up to certain small number of people in a space.

Now system with even larger potential number of people are possible in certain spaces, which involve: auditoriums, shopping malls, cinema theaters, playground, sports ground, stadiums, a streets, concert halls, trains, etc and so on.

And, now the system with even more number of potential people involve small cities. You can observe small sample of them through say live cams available around the world to sample that state in near realtime.

Next is large or mega cities.

next is provinces:

next countries or continents:

and planets and so on..
