Provided are an electronic device and method for providing content to a user. The method includes, based on text of the user, obtaining content corresponding to the text and being adaptive to the user, wherein the obtained content is adaptive to the user based on information regarding the user, which is collected based on the user's behavior on the electronic device; and providing the obtained content to the user.

Device and method for providing content to user

Provided are an electronic device and method for displaying content. The content corresponds to a point of interest (POI) of a user and is adaptive to the user. The content is acquired based on a user input with regard to the POI, which is displayed.

Disclosed are a filament positioning system and a filament positioning method. The filament positioning system includes a bottom plate, a first positioning regulating mechanism and a second positioning regulating mechanism, wherein the first positioning regulating mechanism is configured to conduct positioning regulation of a position of a filament seat on the bottom plate, so that filament seats of different models can be fixed to the bottom plate, and the second positioning regulating mechanism is configured to conduct positioning regulation on the filament; and a detection module configured to collect and display position information of a filament tip and the filament seat, wherein the first positioning regulating mechanism and the second positioning regulating mechanism correspondingly regulate positions of the filament seat and the filament tip according to the position information.
