Reading/Web/Desktop Improvements/Repository/Sticky Header and Table of Contents User Testing/ja

固定ヘッダ と 目次 (ToC) の改善はデスクトップ版の改善プロジェクトに組み込まれています. これらは、読者や編集者がページ全体のナビゲーションやその他の重要な機能にアクセスするためのものです.

これらの変更は、さまざまな情報源からのデータに触発されたものです. 編集者からの要望もありました. また、プロジェクト開始に先立ち、生成的な調査を行ったところ、同様の結論が得られました.

私たちの試作品やアイデアを、さまざまな場面で読者や編集者に試してもらうことを約束しました. テストの取り組みは、固定ヘッダならびに目次は将来を見越して複数バージョンの試作版の準備から着手しました. 次に、ガーナ、インドネシア、アルゼンチンの 3 つの新興地域の読者と編集者でテストを行いました.

私たちの目的は、各プロトタイプの全体的な実用性を判断し、将来的に必要な変更点を見出すことでした. この報告では、このテストの結果を示し、機能自体の次のステップを強調しています.

はじめに
現在、多くの便利なツールや機能は、ページの上部や左側のパネルでしか利用できません. This includes search and language switching, and navigation (e.g. ToC). 人気のあるツールや機能を、ページのどの位置からでも利用できるようにして、アクセス数を増やす試みをしたいと考えています.

今回の調査では、そのための 2 つの可能性を探りました.

固定ヘッダー (Sticky header)
長い記事のページでは、最初の数段落を過ぎてしまうと、利用者はツールなどにアクセスするために再び上にスクロールする必要があります. この対処法を提案するなら、サイトヘッダ（および／または記事のヘッダ）を「固定」することです. これにより、スクロール ダウンしてもヘッダーは画面上部 (コンテンツの上) に固定されます. 仮定の固定ヘッダ上の空間（記事のページを下方へスクロールしても常に表示される）は限られており、便利に使うにはどの機能やツールを載せるべきか調査が必要でした.

Our research in this area focused on answering the question: Assuming we have limited space for persistent tools and functions, which ones would be most valuable to readers, and (separately) to editors?

目次 (ToC)
The table of contents is crucial to the in-page navigation experience. Previous research has shown that users look to it to understand the article structure and contents, and allow for quick navigation to said contents. Currently, most articles have a table of contents near the top of the page.

Our research in this area focused on determining whether a table of contents that is constantly accessible (instead of being just a static element near the top of a page) while browsing an article would provide more value to users than the current setup. Subsequently, we also wanted to determine the best possible way of providing this functionality.

Methods
This research was generated and coordinated by the Design Research team at the Wikimedia Foundation. The prototypes shown to readers and editors were created by the Web team. The research was conducted by three external vendors:


 * URIKA Insights in Ghana
 * Terang Riset Pratama in indonesia
 * CRIBA Research in Argentina

Participants
Vendors in three emerging regions (Ghana, Indonesia, Argentina) were engaged to evaluate table of contents (ToC) prototypes and sticky header (SH) elements/usability. The research was conducted in three languages - English (Ghana), Bahasa Indonesia (Indonesia), and Spanish (Argentina). Each testing location had 6 participants that consisted of approximately ½ newcomers or casual readers, and ½ regular editors on their respective language wikis.

固定ヘッダー (Sticky header)
For the sticky header, two prototypes were created that showed a possible implementation of the sticky header - one reader-focused prototype and one editor-focused prototype. Participants were asked to interact with the prototypes and rate the usefulness of the functionality within the prototypes for their daily usage of Wikipedia

 Research Goals: 


 * Determine ideal elements to include for readers (i.e. logged-out users)
 * Search, article title, language switching, etc.
 * Determine ideal elements to include for editors (i.e. logged-in users)
 * Talk, History, language switching, search, etc.
 * Determine if this list would be different for this cohort if they weren’t logged in
 * Establish relative priority for the elements for each cohort
 * Evaluate prototypes reflecting the elements determined above by cohort

 Research Questions: 


 * Assuming we have limited space for persistent tools and functions (potential customization available for logged in in the future, not planned for logged out), which of the following would be most valuable:
 * Logged-out
 * ウィキペディアのロゴ
 * Article title
 * Section title
 * Search
 * Language switching
 * Edit
 * Logged-in
 * ウィキペディアのロゴ
 * Article title
 * Section title
 * Search
 * Language switching
 * Edit/edit source
 * Talk
 * History
 * Watch
 * Page tools (e.g. move)
 * User tools (opens up a menu that have to do with the user: user page, sandbox, preferences, talk beta watchlist contributions, alerts, notifications)
 * Your favorite gadgets (e.g. twinkle, tool from preferences)
 * Which elements should be persistent?
 * Which elements should be surfaced upon a ‘need’ trigger (scroll-up, hover, other?)

Table of Contents
For the table of contents, participants were first asked to explore the site naturally. A general idea of their opinion on the usage of the table of contents was established. Then, a variety of prototypes were provided for different potential versions of the table of contents. The focus here was on presenting different ways in which the ToC could be accessed from any place within the page. Participants were asked to rank their preferred prototype, as well as to give feedback on the overall idea of a table of contents available throughout the page.

 Research Goals: 


 * Establish a qualitative understanding of how the table of contents is used, i.e. the ways in which it provides value to readers
 * How does this very on very short pages, medium length pages, and long pages
 * Establish an understanding of other methods of in-page navigation are being used (e.g. find in page)
 * Establish an understanding of what value, if any, having access to the table of contents (or a similar navigational tool) from anywhere in the page would offer
 * Is there a separate value in just seeing where you are and what the lay of the land is versus from actually clicking and navigating with it?
 * Evaluate 3-4 different in-page navigation / persistent table of contents solutions (in the form of prototypes)
 * 1) persistent table of contents
 * 2) table of contents via a menu in the article header
 * 3) table of contents via a drawer next to the article

 Research Questions: 


 * Could the table of contents provide more value to readers if it was accessible from anywhere in the article (rather than just at the top)?
 * What are the main use cases of the ToC? How do people think of it?
 * If people interact with the ToC do they typically click on one link, or more than one?
 * How do people use the ToC to navigate the article?
 * What are the main shortcomings, if any, of the current ToC?
 * Does the usage follow any sort of pattern (e.g. long vs. short articles, new vs. experienced users)?
 * What are the main differences (or tradeoffs) users notice between option A (new ToC sidebar) and option B (supplemental ToC)?
 * How does one perceive the contents of an article with/without a persistent TOC?
 * Do we lose legibility / scannability with persistent because it is more narrow?
 * Lower priority questions:
 * Right vs left?
 * How many levels of depth?
 * Numbers vs. no numbers?

Overall
Both the sticky header and table of contents prototypes were received well by all groups tested across languages.

For the sticky header, a number of suggestions were presented and a prioritization of most-useful elements was provided. The prioritization of elements varied by location and logged-in/logged-out status (more details below)

Sticky Header
We asked all testers (readers and editors) to prioritize the list of functionality that would be most useful to them to have access to at all times. Here, the results varied between languages, but were not significantly different. Below, we are providing the combined prioritization (the location-based prioritization lists are available in the full report above).

 Logged-out users: 


 * 1) Article Title
 * 2) Section Title
 * 3) Search
 * 4) Language Switching
 * 5) ウィキペディアのロゴ
 * 6) Edit

 Logged-in users: 


 * 1) Search
 * 2) Article Title
 * 3) Talk
 * 4) Edit
 * 5) Language Switching
 * 6) History
 * 7) User Tools
 * 8) Page Tools
 * 9) Watch
 * 10) ガジェット
 * 11) ウィキペディアのロゴ



We also asked participants to review the prototypes available for logged-in and logged-out users. All users reported positive experiences with the prototypes. Some users requested that the sticky header is always available rather than triggered upon scrolling. Editor participants frequently requested further customization of the sticky header elements. When asked to determine the legibility of the iconography used in the sticky header, many users raised questions on the meanings of several of the icons used in the prototypes, in particular the icon for beta features, gadgets, and contributions.

目次
All users found the Table of Contents to be essential to the reading experience of Wikipedia. The results also gave insight into the primary use cases for the use of the table of contents:


 * Getting a quick sense of the contents of the page - what information is available on the page/is the information the participant is looking for available on the page?
 * Getting a sense of the shape/map of the page and creating a mental model - how is the page organized, which sections are longer than others
 * Direct navigation to a specific section or piece of information

 Behavior change based on user type 

These results varied slightly depending on whether the participant was a newcomer, casual reader, or editor, with casual readers and editors being slightly more likely to interact with the table of contents directly prior to interacting with any other part of the article on medium and long pages. On short pages, the table of contents was used less-frequently. All users indicated that having the ToC only at the top of the article was an issue.

 Newcomers: 


 * Tend to scroll around the article to look for a topic
 * ToC is used a context more than navigation

 Casual Readers: 


 * Tend to go directly to the ToC - it was their first stop to understanding the context of the article.
 * Once context is established, casual readers tended to use the ToC more for navigation than  newcomers

 Editors: 


 * Go directly to the ToC
 * Used the ToC as the main point for navigation (rather than scrolling around)
 * Tended to return to the ToC while reading the article for reference or navigation

The Table of Contents Prototypes Ranking
Participants were asked to interact with five different prototypes of the table of contents. The persistent prototype was the highest ranking of all the available prototypes across all groups. No significant differences were observed based on location or familiarity with Wikimedia wikis (newcomers, casual readers, editors.)

The remainder of the rankings were as follows.


 * 1) Persistent. This prototype displayed the ToC in the left margin of the page. It also included the ability to display all sections and subsections using collapsible arrows on the side of the prototype. Participants indicated that constant access to the ToC was the main reason for the selection of this prototype as it did not require any further clicks or other interaction. Persistent_toc.gif
 * 2) ToC in Header. This prototype presented the ToC within a sticky header on the page. Participants indicated that the ease of use of this prototype was high and particularly noted satisfaction with the clarity of which section and subsection the article was on. However, participants were unsatisfied with the collapsible nature of the prototype and requested for persistence. Header_toc.gif
 * 3) Floating dots prototype. This prototype presented the ToC as a persistent but collapsed element on the side of the page that was triggered on hover. Once again, the persistent element of the ToC was rated highly.  However, participants indicated that they did not like the ToC overlapping the article text when opened. Floating_dots.gif
 * 4) Floating box. This prototype presented a small box in the right bottom corner of the page, which could be expanded into a persistent element. During testing, participants had difficulty noticing the element. When expanded, they also noted dissatisfaction with the ToC overlapping the article text Floating_box toc.gif
 * 5) Back to top button. This prototype presented a button that took participants to the top of the page, where the original ToC is presented. This prototype was not received well across all groups. Participants mentioned that it did not provide any additional functionality that cannot be covered by the browser or the home button on their keyboards. Back_to_Top_ToC_Prototype.gif

Other crucial observations:


 * Participants prioritized persistent access - the best-performing prototype was the persistent one across all tests
 * Participants prioritized having more information - prototypes that contained all sections and subsections performed better
 * Participants did not want the ToC to overlap the content, even in the cases where it was supplementary to the main toc at the top of the page
 * Participants liked getting a sense of location within the article and noted that additions like bolding the title or the section helped with their orientation

Discussion and next steps
This study provided crucial information for the development of the Sticky Header and Table of Contents proposed features. As both features were received well overall by participants, the web team will continue with the development of the features and make changes according to the results mentioned above.

Sticky Headers
We iterate on the prototypes available, focusing on adding the items prioritized as most important to the following sticky header prototypes. We will also explore different triggering mechanisms for the sticky header, including allowing the header to be persistent across the top of the page.

We will be continuing this research into the sticky header by running wider testing of our prototypes with editors and other logged-in users across a variety of different Wikimedia projects.

目次
常駐型の試用版は全てのグループで最上位に入ったことから、反復開発は将来的に計画に組み込む可能性のみ検討します. また折りたたみ式の選択肢は一覧全体を表示が難しいもしくは効率が悪い状況でも応用できないか調べる予定です. たとえば、画面が小さい端末への対応になるかもしれません.

目次に関する研究は引き続き試用版のテスト対象を広げ、さまざまなウィキメディアのプロジェクト群にわたり編集者その他のログイン利用者を対象に行う予定です.
