Different killer Galaxy Note5 S Pen experience

In the Android's fledgling years, Samsung to try to do a lot of exploring, among the most famous result is a Galaxy Note series. In addition to the iconic giant screen, S-Pen is the most obvious feature, the former is also a name of Note in one, and it has been accompanied by the Note series, undergone a full 5 generation of change.

 

In September 2011, the Android 2.3, mainstream screen sizes are 3.5 inch era of early Galaxy Note popped 16:10 5.3-inch screen and the addition of S-Pen shocked the industry. Early S-Pen to support the original send and graffiti handwriting features, screenshot support circles and so on.

Note2 released a year later, S-Pen also have a substantial update, upgrade to 1024, introduced the iconic Air suspension View preview function: S-Pen in 1-2cm at the top of the screen to be induced, and the screen displays the tip of point and can volley hover complete album/video and a detailed preview of the calendar. In addition, the Air suspension preview View is triggered, finger capacitive touch screen ignored to prevent writing hand when hit, greatly improving the experience of writing on the touch screen.

When the Galaxy Note3, Samsung introduced a fan-shaped "floating window command", intelligence memorandum, with the cut with stickers, screen writing, s, search for common operations, such as joined together. Memo added the function of turn handwriting to text, you can copy-and-paste handwritten words into text. In addition, S-Pen also has circle opening calculator, browser shortcut function.

Galaxy Note4, double S-Pen pressure sensitive levels, upgrading to 2048 levels of pressure-sensitive and the software UI and functionality made a lot of improvement adjustments. Galaxy Note5 released this year, the S-Pen from the original drawing into the pop-up, joined out screen writing, scroll the screen and many other useful features.

 

Rush matured floating window command/smart memo/s Note

Metal and glass elements more Note5, S-Pen push the CAP has become a metal material. Press feels and true ball-point pen spring and very close to spare nothing and thinking very addictive, friends jokingly referred to this experience, I can play for a year.

 

Design of the barrel itself changed little, and body paint of the same color, silver tail is the familiar smell of hot. Writing can still change randomly comes with 5 additional written and the replacement of the clamps. Tip is similar to silicone material, you can increase the scratch resistance across the screen, provide the friction needed to write and support. Actual writing feels very soft, but friction is smaller than the real writing.

 

Will vibrate and beep after taking S-Pen, intelligent functions by "side keys, strokes, double-click the floating window and the command" 3 elements interact mainly hosted by the s Note.

Spare S-Pen pen close to the side of the screen click on the button can be called a floating window command, intelligence memorandum, of intelligent multi-screenshots and screenshots to prepare 3 preset function, users can add their own 3 application shortcuts. Previously operating speed is high, but is likely to make many users Miss screenshots of operation long press the side key, and press the side key functions have been canceled in the screen shot.

 

Stroke/size/color options, as well as "floating sticky notes"

Intelligence memorandum supports the reminder settings, you can customize the background color and stroke, and can even be used as a desktop plugin paste it to the desktop. Suspending the entire page, you can adjust the size and position, watching Twitter app and take notes. If you like it, all handwritten notes are "thumbnail" form on the table, the convenience advantage is obvious, but the bias speed record, didn't offer a wide choice of strokes.

 

Illustrator stroke and paint

 

Illustrations polished

General s Note notes a variety of strokes, choice of color, thickness, and can even screen colors (color referred to copy the contents of the screen tip), which is a versatile "graffiti painting". Combined with pressure-sensitive rich stroke, used to paint graffiti and writing is self-evident.

Killer feature: write fast/smart card screen section/character recognition

Note5 new card screen function: rate of screen out the s Note do not require any additional operation minimalist recording mode is available. This mode will ignore the touch of a finger, only S-Pen can write, the machine becomes a real Note (Note notes).

Meet the AMOLED screen black not power-hungry features, card screen was about even long has no obvious impact on the electricity, very suitable for high speed and long period of record. For users who often need to record inspirations and take notes, this is a killer feature.

To the input box will pop up ORC input button

ORC text recognition, when tip refers to handwriting recognition area appears on the box, content will be direct to recognize handwriting to text, call log the contact, and do simple input of time, if not or too lazy to type you can use S-Pen to complete all operations.

 

Screenshot of graffiti and scroll screen

Scrolling screen is now a bring your own capabilities, maximum 22 page, you could almost meet the long tweets, long Web pages are recorded. Full page screenshot can also be edited and written. More violence is, the machines can recognize text in the screenshot, you can copy text contents separately.

 

Automatic cutout screenshots and text recognition

Intelligent multi-screen you can press square, oval and random shapes capture screen contents. More similar to PS in the generation of automatic cutout and clip art library function, which can automatically identify and intercept a target profile, which is the reinforcement of the pasteboard, you can put together multiple screenshots/cutout for editing/scrawling.

 

Left to local amplification, right table insert and clip art library

There are local amplification, simple charts and other features were as an optional plug-in for users to choose. Numerous functions seamlessly, Note5 when I take notes in meetings/classes, with unmatched convenience of cellphones or computers.

 

As a rolling 5-generation products will gradually feel S-Pen to use under the surface there are many designs and details in the use of: System records the S-Pen pull out against losing at the time and after the lock screen reminder, pull back will display a translucent floating Windows, which greatly reduces missed opportunities.

Overall, Note5 S-Pen on this very easy to use. This experience toxic ... ... It experiences even more than the surface and iPad Pro, mobile phone has more competitors in the field. In the cell phone age differences are getting smaller, and have to say that S-Pen is a different case. It's a series, built high on a barrier and confirmed the sentence: S-Pen deserve Note.

Every day we are in the personalization this is what road

Lei feng's network (search for "Lei feng's network" public attention) by writer Xie Defu (micro signal: beancurd191), more than 9 years Internet experience, 6 years relevant experience in personalization, big data. Enter Huawei worked 6 years after graduation, in 2013 start date, focus on large data technology in film and TV, culture, video, entertainment and other fields of application.

Qian days rumors to was Tencent acquisition of today headlines many people should not strange, I is today headlines of faithful user, why I think today headlines do have than other news/information client better, is because it show to I of content are is I wants to see of, with I in above of behavior increasingly more, it show to I of content more accurate, today headlines using of most core of technology is personalized recommended technology.

With the rise of mobile Internet, many of the behavior gradually shifted from PC end user mobile. People spend more and more time on the phone. People everywhere use mobile phones, when in your car, go to the bathroom, eating, even when you walk in you are using mobile phones. Relative to the PC side, mobile features a narrow screen, user time fragmented. And as the volume of information is increasing, it is hard to find what they want quickly through large amounts of information. This experience was very bad, if you are a product manager, if you face the same problem, hope it is helpful to talk about your next.

What is the recommended engine?

If you bought a book on Amazon, you may encounter such a situation, when added to the shopping basket when you choose a book, it will automatically recommend other books to you. For example: people who bought this book also bought XXXX, you may also like XXXX, combining recommendation, buy the book there are several other combinations can enjoy a favorable combination of the book price. These uses are recommended system, it simply recommended system is the study of all acts of the user on the platform, portraits of users, as well as research platform/product. While matching user and product processes.

Recommended application range of engines?

Recommender systems in a wide range of applications in various fields, such as e-commerce sites, video sites, video-streaming platform, news client, literary sites, music sites, and so on. Below is the recommended system at the famous e-commerce Web sites, video sites, some cases of application and effect.

Why recommendation systems are widely used in various fields?

1, directory or search for ways to find desired content, may have to turn on the small screen of the mobile terminal screen, high cost of finding interesting content, poor user experience.

2, approved the substance of recommendations presented to users, all users are interested in, and each user sees is not the same as Amazon CEO Bezos said, to 1000 users accessing the Amazon to see 1000 different Amazon.

3, users now have very many choices, you can choose the diversity and fragmentation of time users open the phone, such as failing to quickly find content of interest, will be leaving soon.

4, personalized recommendation algorithm for user interests recommend precision, helps users quickly find content of interest, and when you're done with a content, immediately recommend things to you, you can increase user stickiness.

5, to help users find more quality long-tail content, general user access only at the top of the 10% about the contents, many will never sink in not found in the database. Vera Bradley phone cases

6, to help balance the ecological platform, avoiding the Matthew effect, featured content is always to get more exposure, popular content never an opportunity is concerned, make content production ecological polarization.

Architecture and core algorithm for recommender systems

Here I did a product as an example to explain, in architecture, could each do is somewhat different, but used some of core algorithms, you should be the same. How to achieve, product managers do not need to focus so fine, just an idea of the principles can be.

Common algorithms including user preferences in Recommender System algorithms, collaborative filtering algorithm (item_base,user_base), Association Rules algorithms, clustering, similarity algorithm (content_base) and a number of other complementary algorithms. Final analysis of results is as follows:

1, according to users ' preference algorithms figure out users ' interests/product, and then recommend to the user.

2, according to Association Rules algorithms, worked out between support and confidence. The most common application is to mix and match, beer and diapers are classic examples.

3, item_base is in accordance with the collective user behavior to calculate the similarity between the goods and users have read and recommend or buy most similar articles to the user.

4, clustering algorithm based on user clustering or clustering of products. Clustering can be recommended for the category, or continues to calculate the relationship between user and product classes.

5, content_base for relevance calculation is based on the properties of the product itself, calculate the similarity between the goods, the most common kind of recommended applications.

6, user_base calculates the similarity between users is based on the collective behavior, such as calculate a and b are very similar, you can like the contents of b, but not seen, recommended to a.

Common scenarios Home guess you like recommending

Due to the smaller mobile screen, one screen to show less content, and users to find the content they are interested in a screen turned down one screen, show personalized recommendation of content in this place, you can quickly catch the user's eye.

Found in sections recommend content of interest to users, you can give users a pleasant surprise.

Association recommended/featured content page for details: details of the contents page to users recommending similar content with the current content.

Read end/video/live broadcast ends recommend: featured content similar to the current.

Recommended search page when search results, you can recommend its content of interest to users.

Personalized recommendation system in application of several key problems

Personalized recommendation system is a very complex system, which not only issues relating to data processing algorithms and system flexibility, but also robust, data sparsity problem, cold start problems, system accuracy and diversity issues.

1, trash data processing: the exception for system data, junk data services developed a set of rules.

2, cold start issue: due to the precipitation of new users access without data, making it difficult to recommend according to user behavior, currently prevalent method is provides interested labels to guide page when a new user first logs on, guiding the user to set, combined with the other algorithms. A better approach is to use social data for users on other platforms.

3, data sparsity problem: can l dimension calculation using a clustering algorithm, and combining it with other algorithms for recommendation.

4, recommended for accuracy and diversity: through the combination of multiple algorithms recommended. Ensure that the recommended result set accuracy and diversity.

Above is a basic knowledge about the personalized recommender system, and want to help.
