research methods and processes

Ii. Main findings:

1. High-End Platform Alert method overview

Banner: Without interrupting the current operation of the situation to inform users of new messages, there will be interference, but do not interrupt, the application should pay attention to stay time and the user to find the path after missing;

2. All kinds of app notification reminder mechanism
"Traffic, virus, schedule and other emergency application reminders"

reminders strongly allow the user to perceive that every new piece of information is reminded; This kind of application is not high in privacy, the Demand for dialog box is very large;

"Call, SMS, IM and other instant conversation tools"

Every new message to remind, in the lock screen if there is a new message, the default display number and sender can meet most users, but also the user privacy protection better. From the actual situation, unread SMS default display preview content, there is no user to provide negative feedback, speculated that the reason may be the user to the default display or not to display the preview content is not obvious, especially in the preview content can be customized. The need for quick response (directly pop-up alert with message content and reply box) is not visible from the data, but can be handled with chat scenes and contact familiarity. For example, acquaintances or consecutive send/reply SMS number to reach N, you can start a quick response mechanism. Notification reminders for such applications are allowed to interrupt the user's current operation in Full-screen state, however, it is best to allow users to customize, personally feel the use of "ios5banner+ custom" way to compare the number of missed calls in the lock screen display content needs to be combined with the degree of familiarity of the numbers to distinguish (such as familiar with the number of increased callback function , strange numbers show attribution and number of rings, etc. the results show that the user dialog box needs a small proportion, may be taken into account the privacy of IM reminders and SMS similar to the demand for a dialog box is lower, but do not need a variety of ways to collaborate, prompt tone, vibration and notice bar can be

"Mail, microblogging, SNS and other Delay class message tool"

in the mail, microblogging and SNS, such as Delay class message tool reminders, notification bar This kind of quiet and not overlooked form is very popular if it is a continuous number of message push, only need the first reminder, followed by not using a reminder in the lock screen interface, new mail Only show the number can meet most users, Microblogging and SNS need to display the number and sender, but the sender's display mechanism to take into account the number of new messages and senders, if the number of excessive, need to establish a truncation or ellipsis mechanism.

"Application market and News class applications"

and News class apps new messages do not require a system reminder, you can consider an application. This kind of message is not important not urgent, in the system to remind not only disturb the user, but also to the user caused "waste of traffic" concerns.

"Other tips."

If the user sets the screen lock, be aware that the lock screen interface does not display private information, for example, the content of the chat tool; the computer system of unread messages needs to be optimized, there is currently read but not counted by the system, still reminding unread; When the lock screen sets the password, pay attention to unlock the operation path, for the lock user, To view a dialog-type reminder, you need to repeatedly enter the password unlock, the operation path is too long, it is recommended that the message type to consider the option of setting up a direct operation. When the reminder to pay attention to system scenarios and user scenarios, system scenarios such as lock screen, full-screen and desktop and other scenes, the need for message reminders is different, user scenarios such as sleep at night to be careful to remind. Use a variety of reminders to help users to determine the type of message, such as the use of sound or vibration frequency, intensity and the color of flashing lights, and so on helps users identify the type of new messages, so that users do not light the screen at the same time the type of pre-message. Take care of special groups and special use scenes, such as increasing the voice reading function. Important unread information such as a schedule increases the intensity of reminders, such as continuous reminders, or increases the intensity limit of sound and vibration
