Android GUI discussion

(note from June 17 2014 conf call)

Goals

We'd like the GUI to

• convey the feeling that the device is actively making a contribution; i.e. it should show change in some way.
• convey the feeling of community and power in numbers; this device is part of a large set of device, and the volunteer is part of a large group of people.
• encourage the user to run BOINC more on this device (i.e. leave it plugged in more).
• encourage the user to run BOINC on their PCs as well.

And

• we should show information graphically rather than textually as much as possible.
• when we show numbers, they should be in units that are easily understandable to the volunteer, e.g. hours of computing rather than credits.

GUI structure

The GUI currently has a set of pages, or "tabs": projects, tasks, prefs, notices. The projects and tasks tabs show lists; each list item can be expanded into a page showing its details.

Currently there's no top-level page, so there's no place to show info for this device as a whole. Maybe we need to add this.

I think the Tasks tab is good more or less as is, except that it should always show a progress bar for each task.

Most of the following idea apply to the Projects tab and the project detail page.

Ideas

Computing time

(By "computing time" I mean the time that BOINC is allowed to compute; this is not the same as CPU time).

We could show

• Computing time in last 24 hours
• Computing time in last week

We could show these graphically as pie charts or bars. We could also show them as "time lines" showing the specific times when computing happened. This would show, e.g., if computing was toggled because of battery charge or heat.

We could show total computing time, either textually or as a graph showing its increase over long time scales (weeks, months, or since the beginning).

Task completion

We could show the # of tasks completed

• per project, or summed over projects
• in the last week, or since the beginning
• textually, or as a graph

We could show a time line with horizontal lines (color coded by project) showing the lifetime of each task.

Contribution as fraction of whole

For the various quantities (computing time, credit, tasks) we could show the device's contribution relative to the project as a whole. E.g. "Einstein@home processed 1,234,567 jobs this week, and your device did 2 of them".

It's not clear whether volunteers would find this discouraging.

Contribution relative to average volunteer

For the various quantities (time, credit, tasks) we could show the device's contribution relative to the Android average. E.g. "Your device computed 7.4 hours per day, and the average is 6.9". Or we could show the distribution of the quantity, and where this device lies on the distribution.

Badges

Projects can grant "badges" for any kind of achievement:

• total credit
• average credit percentile (i.e. top 1% or 5% of volunteers)
• number of message-board posts

Badges have corresponding images and textual descriptions.

The GUI should show badges, and it should notify the volunteer when a new badge has been earned.

PC suggestion

We could say, somewhere in the GUI, something like "Want to help more? You can also run Einstein@home (and ...) on your desktop or laptop computer. Click for more info.".

We should probably make the GUI aware of whether the volunteer is in fact already running BOINC on other computers, and if so not show this message.
