HabitLab

HabitLab is a Chrome extension to help you build better habits online. HabitLab aims to help people achieve their goals online (ie, waste less time on Facebook) by trying out different interventions in their browsers and seeing what works best.

habitlabmobile's Issues

experiment to quantify effects of repeated exposure to interventions on effectiveness and attrition

objective: see how much showing users an intervention repeatedly has on their retention (hypothesis: after repeated exposure they will uninstall, aka low retention rates) and on efficacy (hypothesis: efficacy aka how long they spent will improve to a point and asymptote off)

interesting things we can then do as follow up:

differences among users for the optimum frequency of showing them an intervention.

ramp up in frequency. so start at every one minute and then increase frequency. or other non-linear approaches

can we detect potential attrition before it actually occurs? for example: perhaps the user starts touching or there's small accelerometer motions that indicate frustration

approach (implementation)

when users install the android app, we vary them among conditions for how frequently we show them the intervention

some have the interventions showing more frequently, some have them showing less frequently

accessibility service stops receiving events as soon as habitlab app is closed

curiously this occurs on my le max 2 (android 6.0.1) but not on my galaxy s3 running lineageos (android 7.1). so it may be device/ROM specific, or specific to particular android versions. probably want to check to see how widespread the bug is?

steps to reproduce

open habitlab app. turn on accessibility service

then close all habitlab windows. open habitlab again. it will prompt that the service is not running ( from checkAccessibilityPermission in PermissionUtil.js )

adding various console.warn to onAccessibilityEvent calls shows that the service continually gets the calls, until the habitlab app is closed.

can be reproduced in the version on the play store as well

will we need to run a foreground service or can this be resolved some other way?

accessibility service crashes, also manage targets shows "no results"

stack trace below, seems to be something related to the target apps in the accessibility service

Not available in Canada

Why does Google Play say the app is not available in my country? What is the advantage of excluding Canada?

Where in the code is the exclusion? Would there be an issue if I forked the repo and submitted app so it could be installed and used in Canada?

experiment design

hypothesis

we hypothesize that novelty has benefits to effectiveness and/or attrition. we want to see whether this is true (this experiment) and measure its degree.

if this turns out to be true, in follow up studies we hope to be able to utilize this information for intelligently picking interventions / crowdsourcing them taking into account novelty

research questions

effectiveness: comparing the high novelty condition weeks to the low novelty condition weeks, is more time saved relative to baseline (shorter sessions)

attrition: on weeks where the high novelty condition is shown, is there a difference in uninstall rates (hopefully lower) relative to low novelty weeks

experiment itself

within subjects design

2 weeks in duration

each week users are either in a high novelty or low novelty condition

high novelty = show randomly chosen message from a large pool

low novelty = show same message always. (just chosen at install time randomly)

in all weeks, half the time we don't show any message. this is the control so we know how much the baseline time would have been without any interventions (hence we know how much time is being saved)

timeline

hopefully should launch before the end of this quarter
