Individual homework 2--English learning app case study

I. Research and evaluation

1. The experience of getting started:

The first impression of Bing Dictionary is simplicity, simple and fresh interface, no ads, clear function, convenient operation. The "Daily sentence" and "Featured articles" of the homepage feel very good, but the word associative function, although beautiful but not practical enough. "Word Challenge" and "Oral training camp" are very practical and have created a good learning experience for English learners.

2.BUG (defects in software):

According to the definition in the law of construction, bugs can be broken down into:

1) Symptoms: That is, from the user's point of view, the software what the problem.

2) Program error: From the point of view of the code, what error in the code caused the problem of the software.

3) root cause: The root cause of the error, which is the cause of the code error.

Microsoft Bing Dictionary (Android version) specific bugs are as follows:

BUG1: words cannot be interpreted in this part of the word.

BUG2: The language of the entire interface will change successfully after the language settings have changed and only some of the word languages have changed and must be exited after logging back in.

BUG3:"a daily sentence" To share the link click will appear garbled (and QQ will).

BUG4:"Back word" learning module in the upper left corner of the learning progress disorder, each quit learning to go in, learning progress is not the same.

BUG5:"memorize words" in the Learning module, click the "Impression" word, will appear in the "Mastered" word list.

BUG6: Clear History query record is invalid, return to query, history still exists.

2. The same product (Youdao dictionary, PowerWord) comparison:

• Interface

Bing Dictionary: Simple and intuitive interface. This interface design makes it very convenient for users to use them. At the same time, the function is clearly divided, and the user experience is greatly improved with no embedding ads.
Youdao Dictionary: Overall page layout is also comfortable, the interface to cold color red and white-based, simple atmosphere. Home Page recommended a wealth of subject knowledge, including literature, film and television, science and other aspects, but also joined the relevant mapping, greatly enhanced user interest and visual experience.
Kingsoft PowerWord: The interface is very mediocre, icon color slightly failed, multi-color so that the overall visual feeling is not refined, not elegant. Boot ads and Home page implant ads This also pulls down the overall goodwill degree.

• Word Library richness

By querying several commonly used abbreviations: Ruok (is you OK?) ), AFK (away from keyboard), thx (thanks), ttyl (talk to you later), ASAP (as soon as possible), BBL (being back later), the result is as follows:
Bing Dictionary: can only query to Ttyl, ASAP.
Youdao Dictionary: In addition to BBL can be queried.
PowerWord: In addition to THX, BBL can be queried.
In conclusion, the word storehouse of Youdao is the richest, Jinshan is the second, while Bing Dictionary has the lowest richness of thesaurus.

• Translation accuracy

Using three dictionaries to translate "as a junior student, we have to study hard, make progress every day", three dictionaries give three kinds of answers:
Bing Dictionary: As a junior student,we should study hard and make progress.
Youdao Dictionary: As a junior student, we should good good study, day to up.
PowerWord: As a college student, we should study hard, every day.
In contrast, the translation of the Bing Dictionary is the most accurate, powerword lesser, and Youdao translation is more inaccurate.

• Multi-lingual Translation

Bing Dictionary: Focus on the translation of English and Chinese, do not provide translation of other languages.

Youdao Dictionary: Not only support the translation of Chinese and English, but also support the Chinese and Japanese, Chinese and Korean and other languages of the translation. Users only need to enter keywords in the search box, select a language, and then click the Search button to get the pronunciation, interpretation, authoritative dictionary, usage, sample sentences, and encyclopedia associated with this keyword.

PowerWord: Support the translation of Chinese and English, but also support the Chinese and Japanese, Chinese and Korean, and other languages of the cross-translation.

• Learning function

Bing Dictionary: Learning module in the "Oral training camp" and "I love to speak English" for the provision of sub-categories of real-time oral practice, improve the level of oral English. In addition, Bing Radio, Word Challenge and so on to provide users with listening training and word memorization and other aspects of the learning function.
Youdao Dictionary: "Fine Class" to provide users with a complete course live recording system. Users can quickly play, replay lessons and interact with the teacher in real time by commenting. At the same time, the focus of the function of the user in the course of the lecture, you can mark the key part of the review, to provide students with the best experience of listening. But there is a slight shortage of oral training.
PowerWord; The English learning function is mainly focused on dictionaries and listening, contains a variety of copyright dictionaries and rich real-life recordings, and has a variety of common dialogue practice, for English learners to provide a wealth of learning materials.

In summary, Bing Dictionary, Youdao Dictionary, PowerWord in the interface, thesaurus richness, translation accuracy, multi-lingual translation, learning function 5 Modules of the basic comparison results are as follows:

Contrast	Interface	Word Library richness	Translation accuracy	Multi-lingual Translation	Learning function
Bing Dictionary	Simple	So so	Excellent	No	Excellent
Youdao Dictionary	Simple	Rich	So so	Yes	Good
Jinshan dictionary	  General	  good	  good	 	  good
