Generating and presenting directional bullet screen

A computing system of generating and presenting comments relative to video frames among selected users in a network community, comprising:

• at least a processor;
• and
• at least a memory communicatively coupled to the at least a processor to configure the at least a processor to:
• receive message data from a first user, the message data comprising at least one comment on a video;
• determine that the at least one comment is restricted to be viewable by a first selected group of users based on an input by the first user;
• determine that user information associated with the first user satisfies at least one predetermined condition;
• generate a first directional bullet screen based on the message data received from the first user, the first directional bullet screen comprising the at least one comment, context information indicating that the at least one comment is to move across at least one frame of the video, and directional information indicating that the at least one comment is to be presented to and viewable by the first selected group of users only;
• receive at least one restriction on viewing the first directional bullet screen from the first user;
• receive a request of accessing the first directional bullet screen from a third user;
• determine whether user information associated with the third user satisfies the at least one restriction;
• transmit the first directional bullet screen to the third user based at least in part on determining that the user information associated with the third user satisfies the at least one restriction;
• deny the request of accessing the first directional bullet screen by the third user and cause a display device used by the third user to return to a previous display interface immediately before the third user sent the request of accessing the first directional bullet screen based in part at least on determining that the user information associated with the third user does not satisfy the at least one restriction;
• transmit the first directional bullet screen to a fifth user who is watching the video based on determining that the fifth user is among the first selected group of users, wherein the at least one comment is displayed by moving across the least one frame of the video based on the context information and is viewed by the fifth user;
• and
• transmit a public bullet screen other than the first directional bullet screen to a sixth user who is watching the video based on determining that the sixth user does not belong to the first selected group of users, wherein the public bullet screen comprises a second comment on the video that is viewable by any user and context information indicating that the second comment moves across one or more frames of the video;
• wherein there is an upper limit of a number of the first selected group of users who are allowed to view the first bullet screen;
• wherein the first bullet screen has a valid period after which accessing to the first bullet screen is automatically invalidated;
• and
• wherein the upper limit of the number of the first selected group of users and the valid period of the first bullet screen are determined based on an amount of platform currency spent by the first user.

A non-transitory computer-readable storage medium bearing computer-readable instructions that upon execution on a computing device cause the computing device at least to:

• receive message data from a first user, the message data comprising at least one comment on a video;
• determine that the at least one comment is restricted to be viewable by a first selected group of users based on an input by the first user;
• determine that user information associated with the first user satisfies at least one predetermined condition;
• generate a first directional bullet screen based on the message data received from the first user, the first directional bullet screen comprising the at least one comment, context information indicating that the at least one comment is to move across at least one frame of the video, and directional information indicating that the at least one comment is to be presented to and viewable by the first selected group of users only;
• receive at least one restriction on viewing the first directional bullet screen from the first user;
• receive a request of accessing the first directional bullet screen from a third user;
• determine whether user information associated with the third user satisfies the at least one restriction;
• transmit the first directional bullet screen to the third user based at least in part on determining that the user information associated with the third user satisfies the at least one restriction;
• deny the request of accessing the first directional bullet screen by the third user and cause a display device used by the third user to return to a previous display interface immediately before the third user sent the request of accessing the first directional bullet screen based in part at least on determining that the user information associated with the third user does not satisfy the at least one restriction;
• transmit the first directional bullet screen to a fifth user who is watching the video based on determining that the fifth user is among the first selected group of users, wherein the at least one comment is displayed by moving across the least one frame of the video based on the context information and is viewed by the fifth user;
• and
• transmit a public bullet screen other than the first directional bullet screen to a sixth user who is watching the video based on determining that the sixth user does not belong to the first selected group of users, wherein the public bullet screen comprises a second comment on the video that is viewable by any user and context information indicating that the second comment moves across one or more frames of the video;
• wherein there is an upper limit of a number of the first selected group of users who are allowed to view the first bullet screen;
• wherein the first bullet screen has a valid period after which accessing to the first bullet screen is automatically invalidated;
• and
• wherein the upper limit of the number of the first selected group of users and the valid period of the first bullet screen are determined based on an amount of platform currency spent by the first user.
