Personal risk monitor graph

[jeschaller]

Feature description

To monitor the personal risk behavior, it would great the app shows a graph risk contacts vs. date.

Problem and motivation

The app shows warns or shows only the current value of risk contact. To make the persons more sensitive for rising infection risk, a graph would show an increase of contacts over time. With that, the users can be get a sensor, how his personal risk, that he can optimize by behavior change.

You want to show contacts with ppl who later tested positive, right?

If you have an Android device you can already use @mh-'s corona-warn-companion to get this information, but I agree that it would be nice to also have the option to directly see this in CWA 🙂.

@daimpi> You want to show contacts with ppl who later tested positive, right?

This could be one indicator, that is straight forward and shows direct COVID contacts. With a right framing of values into a user understandable message the aim is to raise the awareness of personal risk can be achieved.

Thinking about that, another parameter could be a more statistical parameter calculated from the product of total number of day contacts multiplied by the local current incident rates (getting from the COVID-Dashboard). This maybe limited by the changing id of the phones, but I think this could resolved by statistical methods and assumptions. At the end this results in a parameter of the personal potential statistical corona events per day (ppsce/d).

If the persons opt-in, the app could also send anonymus values of the potential corona events for a region (Landkreis etc.) to a central server to monitor the social distance of the user.
That would help to check if the measures would decrease the social distances and what is the distribution of social distancing users.

If this can be assessed users with higher ppsce/d-values than others in the area can check their behavior in comparassion to the mean population.

The number of non-positive contacts, is something CWA can't assess: #124 (comment)

May I add here to the beautiful Graph idea the request, to see also all negative test results - documented and qualified by test result or as not qualified - also in here - see details in comment #115

@informationiskey

[…] documented and qualified by test result or as not qualified […]

what do you mean by that?

[informationiskey]

@daimpi If you are just a "user" of the App - assuming no contact so far, it is "negativ, unqualified" but a contact.
If your app is in warning state for a positive contact to you - "positiv, unqualified"
If you have documented your positive Testresult - "positiv,qualified" and
if, as proposed, you have documented your negative Testresult - "negativ, qualified"
qualified as something from a "maturity" level - in this case only with [0;1;2;3]
Thinking further - if a next generation framework/API would support this - it could be extended also to
if you have been positive, but now you are happily convalesced - after let's assume 4 Weeks time after documenting beeing positiv - "negativ, immun, unqualified" - meaning also, no spreader but a blocker for positive contacts.
if you have been happily convalesced and tested negativ - "negativ, immun, qualified" - trustful blocker for positive contacts.
increasing the maturity level to [...;4;5]
Best regards.

Ah I see… I think I now understand what you mean… I personally still don't think this is a good idea for the reasons desribed over at #115 (comment) but that is o/c debatable.

Just to mirror some info from over at corona-warn-app/cwa-app-android#1438:

Implementation of this feature will require ENF v.1.5+ and ExposureWindow mode and I hope that we see a switch to the new API soon, especially now that Google strongly recommends switching to the new API (CWA is currently still using v1 legacy mode ^^).

Other related issues:

• Show more details on encounters: Show more details about "risk encounters" #100
• Show day of encounter also for green encounters: Show date of Low-Risk encounters #178

+💯

This would also help people to see how much social activity they have. Very useful. Especially in times of Kontaktbeschränkungen.

As stated above: CWA can't know how many non-positive contacts you had, only how many positive ones.

[Ein-Tim]

This will be integrated (only the number of positive contacts), see: #206 (comment)

Starting with v 1.12.0 it will be possible to see when you had encounters:
