Improve our Tor diagram based on results from usability tests (v2)
Not done before publishing #18450 (closed) with 4.22.
Current version on our website:
I did some basic tests in #18074 (closed). Next steps is to prototype some improvements:
Improve the color coding of the links and relays
Try not to make the line thinner: it's not the encryption getting weaker
Add labels to explain the security properties
Prototype with first improvements tests during #18784 (closed):
Results from #18784 (closed):
On "Hidden content" and "Hidden origin":
- The shape felt like a placemarker or scary stop sign to P2 and P3. We could use a dialog bubble or a more neutral shape, maybe even without the line connecting to the Tor circuit.
- P2 and P3 thought that “Hidden Origin” and “Hidden Content” were the names of each place or a spyware being inserted and not security properties. We should write “Tor hides your content” and “Tor hides your location” instead.
On the circuit line:
- The hidden yellow line makes it more clear that it's the same information traveling. We could either stick with a plain line or try with a dotted line maybe.
- The yellow line getting thinner seemed like the encryption is getting weaker to P1.
- Nobody comments on the 3 colors corresponding to the color of the relays. I'd line to test a version with peeled cable at origin (@anhdres) has this already somewhere and a line of constant width between the relays.
On the origin and destination:
- The picture of the server was unclear to P1, P2, and P4.
- The location line of the server pointing to the middle relay was confusing to P1. I think that we could keep the location line for the relays but remove them for the origin and destination.
- The envelope going out of the laptop was more clear.
I have footage of all this and could share it with @anhdres.
