QQ computer Butler design bit to share

May 25, QQ computer Butler 5.0 release, launched a strong four nuclear trojan killing engine, killing ability to improve quickly, in the card rice and other professional assessment forums have good results. Look at their own follow-up Trojan killing module from 4.5 to 5.0 a little progress, very happy, at the same time very fortunate to be in such a force to the team, to bring you a free and easy to use security software. Here simply share some of the design process of the intravenous drip, I hope to be inspired by everyone.

Why to think before optimizing?—— design

Look at the 4.5 version of the Trojan screen, in the design optimization before I ask myself, why optimization?

(1) Trojan killing function of the design optimization direction is?

(2) The user in the Trojan killing process will have difficulties?

(3) The user to the current Trojan killing function evaluation how?

...... On its own subjective judgment, the advantages of the interface is clear focus, three killing buttons is also the main operation of the current interface, in line with user scenarios. The lack of interface layout is not coordinated, more blank areas, the interface is not beautiful. But the subjective judgment sometimes has the deviation, can not serve as the basis for the follow-up optimization design. At this time, the complete user research is the premise of the well-founded design.

The premise of designing with reasonable and reasonable--user research

In view of the previous questions, before optimizing the design, the user usability test and eye movement experiment were carried out for the Trojan killing function. There are three purposes:

(1) To understand the current situation, to assess whether the availability of Trojan killing function to meet the needs of users;

(2) Observe the user, through the eye Movement experiment to evaluate the user's attention to the interface in the process of using;

(3) After the design comparison, the test results can be used to optimize the comparison of the design, to see whether the subsequent optimization improves usability. Through usability testing and eye movement analysis of the results of the conclusion:

(1) The user has no difficulty in using this feature.

The user in the Trojan killing before the purpose is very clear, so the beginning of the killing page to users without cognitive difficulties, stay for a short time.

(2) There is no cognitive difficulty to the main killing button.

Users of the "Quick Scan" and "Comprehensive scan" understanding is not difficult to understand the "custom scan" blurred, while "Custom Scan" most users generally do not use, Custom Scan button clicks in the amount of about 3%.

(3) The scanning has the fixed habit.

Users choose "Fast killing" or "overall killing" is a fixed habit, that is, the general will be explicitly selected a fixed button. For example, in most cases, "quick Scan", in the noon meal time to conduct a "comprehensive scan" and so on.

(4) The scanning process of the page attention is low.

During the scanning process, the user typically minimizes the housekeeper or switches the tab page, and stays short during the scan. Clear Design Optimization Direction

After the user research, especially after the research data support, the design optimization direction naturally is very clear. In the development of resources to break the focus of the housekeeper's own killing capacity, the use of limited resources to do some detail optimization, there will be no greater adjustment. Focus on the killing ability of the display and killing process optimization.

(1) To increase the killing engine information, improve the ability of the Trojan horse display.

(2) To optimize the process of killing various situations in the prompt language.

(3) Optimize the information display during the scanning process.

A little experience

1. How to enable users to study practical support detail design?

User research and the designer's cooperation, the best way is the designer to participate in the process of user research, rather than just put forward with research needs, let the research colleagues give the conclusion. Full participation in the process of research, you can communicate directly with the user, in this process, that is, you can get the content directly, but also from the user to get a lot of inspiration, to avoid the design and use of the gap between the research. 2. Quick-use research is the way to find the design basis with low cost

Rapid use of research is to use a very short time, to find colleagues in the company interviews, usability testing, for their own design to find the basis for design.

Example of a job:

Before doing a U disk protection, and product discussion when proposed: after the user inserted a U disk after the computer butler directly help users to open U disk security. The reason for our analysis is that most users will want to use the U disk immediately, then we will directly help users open up, while conducting a security scan. In order to verify whether the user has this demand, I from the side of the interns, colleagues where the rapid use of research, the results let me plunge glasses, find 10 students, 10 students have chosen not to open automatically.

10 users have chosen to open a U disk, the main reason for the following 6 points:

(1) Accustomed to open themselves, afraid of directly open unsafe.

(2) Afraid of running multiple programs, insert a U disk directly after the opening will cause computer crashes.

(3) Most of the time just put things into the U disk, do not need to open.

(4) If the content has privacy, open directly by others see bad.

(5) Like to control their own U disk.

(6) Insert U disk does not necessarily need to immediately use, directly open there harassment.

The whole process spent 10 minutes, the conclusion let us deny their previous thoughts, that we think more in this detail point, very timely. 3. Reasonable and reasonable to avoid unnecessary PK

Design is the most afraid of the situation is in a dispute point of entanglement, and the way to avoid this situation is to have a reasoned design. A comprehensive user study of the conclusion, although may cost a certain amount of resources costs, but can be for subsequent versions of the design to find the design basis, in peacetime work, greatly reduce the cost of communication, a lot less to go detours.

We are doing design, the most likely problem is to consider themselves as users, for their own design. The effective way to avoid this situation is to have more contact with the user and benefit.

At present, the QQ computer Butler design team insist on monthly users to carry out usability testing, for our design to find a lot of credible basis, but also in the process of touching a lot of creative spark.
