Reading/Web/Desktop Improvements/Features/Collapsible sidebar/ja

画面左側のメニュー (サイドバー) に柔軟性を持たせ、閲覧者や編集者が折り畳んだり広げたりできるようにしたいです. それによって、コンテンツに集中しやすくなります. 同時に、必要なときに機能を使えるようになります.

この機能では、このプロジェクトの主な目標のうち2つを推進する所存です. 1番目に、利用者の皆さんが閲覧でも編集でも、コンテンツそのものに集中できるようにします. もう一つの目的は、重要な機能として編集や変更履歴のボタン類、言語切り替え、検索に注目します.



機能の説明と要件
折りたたみ式サイドバー機能は画面左上の角にボタンを導入します. このボタンを押すと、サイドバーごと内容を隠します. 開くには - もう一度、ボタンを押します.

ログインした利用者なら、サイドバーを折りたたみたいという個人設定は保存されます. つまり、サイドバーを折りたたんでおきたい場合は閲覧や編集を終えた後、次のページを開いたときにサイドバーは折りたたんだままで、開いたままにしておきたいときも同様です.

ログインしていない匿名利用者の場合は、ブラウザでそのときに利用した特定のウィンドウでのみ、その選択が保存されます.



設計要件とガイドライン
この機能の試作品をご用意しています.

制約
現状では、いくつかのプロジェクト (例：朝鮮語版ウィキペディア) がすでに既定で同様の挙動を導入済みです. これらウィキのコミュニティと緊密に連携して、折りたたみ式サイドバーのバグその他の問題点をなくしていく所存です.

すでに皆さんのコミュニティでサイドバーを折りたたむガジェットを導入の場合は、ぜひご連絡をください.



ユーザーテスト


編集者向け
複数のウィキにわたり編集者を対象に、折りたたみ式のサイドバーの試作品でフィードバックラウンドを実施しました. 一斉通知バナーを使用して編集者を試作品の探索に招待し、フィードバックを提供してもらいました. フィードバックを寄せてくれた利用者の大半は、個人で使うなら既定で折りたたんだままのサイドバーを支持し、これは特に閲覧に便利とのことでした. フィードバックに関して、課題の指摘や繰り返し開発の詳細は報告書をご参照ください.



読者向け
サイドバーの試作品は、独立の利用者テスト会社 Hureo (本拠地インド)と共同で行われた読者を対象にした利用者調査でもテストされました. 調査期間中には、ウィキメディアのプロジェクト群に慣れていない読者、またウィキメディアのプロジェクト群をよく使うカジュアルな読者を対象にしました. テストは英語、ヒンディー語、テルグ語、タミル語、マラーティー語で実施されました.

読者は折りたたまれたバージョンのメニューを強く支持し、現状のバージョンよりも読む体験が良くなったと報告しました.

この調査の全文結果を近々、公表する予定です.



定量的テスト
変更を行って以降、匿名およびログインした利用者がサイドバーを使用している間の行動パターンを観察することができました. この報告はこれまでの所見を提示します. We hope to use this data in future iterations of the collapsible sidebar functionality.

Study questions
When measuring the usage of the sidebar, we wanted to consider the following set of questions:


 * What is the frequency that users collapse and uncollapse the sidebar
 * What is the difference in interaction with sidebar links between people with the sidebar collapsed (the majority of the time) versus uncollapsed (the majority of the time). In other words, once the sidebar is collapsed, do users open it when they need to, or do they just ignore it altogether?
 * What is the overall difference in interaction with sidebar links before and after the change
 * In particular, what is the overall difference in interaction with the donate link?

What is the frequency that users collapse and uncollapse the sidebar?

 * Between July 22 and August 31, 2020, there were 28,745 unique sessions that included a click to collapse and/or uncollapse the sidebar. This represents only about 0.13% of all recorded sessions using the Vector 2022 skin and 13.67% of all Vector 2022 sessions with a click recorded.
 * Since the sidebar was set as uncollapsed by default, there are more total clicks to collapse the sidebar. However, there are roughly the same average number of clicks per session to either collapse or uncollapse. Average Clicks Per Session to Collapse: 1.37; Average Clicks Per Session to Uncollapse: 1.38.
 * French Wiktionary had the lowest average sidebar clicks per session (1.87) while Persian Wikipedia had the highest (2.94).
 * Logged-out users have more than twice the number of collapse events compared to uncollapse events, likely because the state of the sidebar for logged out users is not preserved.
 * Most sessions overall included just one-click to either collapse or uncollapse the sidebar. Logged out users have a higher frequency of one sidebar clicks per session while logged in users have a higher frequency of two clicks per session.



What are the different interaction types with the sidebar?

 * For the majority of sessions (81.88%), the sidebar was collapsed and/or uncollapsed just once. For sessions where the sidebar was collapsed only once, 34.5% sessions kept the sidebar collapsed the majority of their session time and 65.4% of sessions had the sidebar uncollapsed the majority of their session time (did not collapse it until towards the end of their session).

What is the overall difference in interaction with sidebar links before and after the change?
Note re approach:

Since this was deployed as opt-out to all users on the test wikis, there is not a random, equal split of users between the two Vector skins. A direct comparison cannot be made as there may be some bias. The old skin version was only available to those who explicitly opted out. There were more users who saw the new version. However, we compared the average interactions per session for each skin type. This was to control for the different number of users and confirm if there were any significant differences.

Note: Data in these comparisons may still be affected by self-selection bias between the two groups. We also reviewed data from a two-week period before and after each test wiki's deployment date to confirm if there were any significant changes.


 * The Legacy Vector has a slightly higher number of total sidebar link clicks per session (4.68) compared to Vector 2022 (3.63). This is also true on a per wiki basis except for on French Wiktionary and Portuguese Wikiversity, which have a slightly higher average number of total sidebar link clicks on the new skin compared to Legacy
 * Clicks to the donate link do not appear to be affected by the new skin version. There is a slightly higher number of average clicks per session on the Vector 2022 (1.11) compared to Vector 2010 (1.06).
 * There was a decrease (-9.15%) in the overall total number of sidebar link interactions comparing the two weeks prior and two week following the deployment of the collapsible sidebar across all test wikis. However, this percentage is likely inflated due to seasonality effects (previous year's data was not available using webrequest to complete a year over year analysis).

Discussion and next steps
''' Based on the results above, we have learned that logged-in and logged-out users have very different behavior while using the sidebar. ''' Logged-in users tended to, overall, collapse the sidebar and leave it collapsed. As we understand it, not many of the items in the sidebar were useful to them. However, the rate of uncollapsing also indicated that users are aware that, were they to need to navigate to an item in the sidebar, that option was available to them.

Logged-out users, on the other hand, tended to collapse and uncollapse as needed. This indicates that they had a greater need of the items in the sidebar and that their behavior was more task-based, rather than indicating an overall pattern.

Based on the above findings, we took the following actions:


 * Making the sidebar collapsed by default for logged-out users
 * Keeping the sidebar uncollapsed by default for logged-in users

We decided to continue to monitor the above patterns, in particular the decreases in clicks to links in the sidebar. We will work on it again based on future findings.



リリースの日程
We began deploying the first iteration in May 2020 to Office Wiki and Test Wiki, and plan to continue to our early adopter wikis in following months. 詳細は機能のメインページをご参照ください.
