Abstract: An interaction method and apparatus, an electronic device, and a computer readable storage medium are provided according to the embodiments of the present disclosure. The interaction method includes: displaying an object recognition component on a first page; jumping from the first page to a second page in response to detecting a trigger signal to the object recognition component; displaying a scan area on the second page to recognize an object in the scan area; displaying, in response to recognizing the object in the scan area, a result display component corresponding to a quantity of the recognized object on the second page; and jumping from the second page to a third page in response to detecting a trigger signal to the result display component, where a content of the third page is related to an object corresponding to the result display component.

Abstract: Systems, apparatuses, and methods for scanning a shopping space. The system pace comprises a locomotion system of a motorized unit, a camera system, and a central computer system. The central computer system is configured to receive motorized unit location information from the locomotion system, the motorized unit location information comprises a plurality of sets of coordinates each associated with a timestamp, receive item identifier instances from the camera system, wherein each item identifier instance is associated with a timestamp, and determine a location for each item identifier instance based on the timestamps associated of the item identifier instances and the timestamps associated with the plurality of sets of coordinates of the motorized unit location information.

Abstract: Example icon data migration method example electronic device, and example computer-readable storage medium are provided. In one example method, a link establishment request sent by a migration device is obtained, where the link establishment request includes a device type of the migration device, and the device type of the migration device includes a single-screen device or a multi-screen device. Reference icon data of the migration device is obtained based on the device type of the migration device and a device type of a to-be-migrated device after a link is successfully established. Actual icon data is calculated based on the reference icon data and an obtained icon layout of a first display screen. An icon corresponding to the actual icon data is displayed based on the icon layout.

Abstract: A method for treating waste gases containing low-concentration volatile organic compounds (VOCs) based on combination of adsorption and in-situ temperature-varying catalytic ozonation, relating to treatment of organic waste gases. In the method, a VOCs-containing waste gas is fed to an adsorption bed for enrichment, which includes a low-temperature regeneration process and a high-temperature regeneration process. A catalyst with high adsorption capacity and catalytic activity is loaded on the adsorption bed.

Abstract: The present invention disclosures a critical dimension error analysis method, comprising: S01: performing lithography processes on a wafer, measuring the critical dimension (CD) values of the test points in each of the fields respectively; M and N are integers greater than 1; S02: removing extreme outliers from the critical dimension (CD) values; S03: rebuilding remaining CD values by a reconstruction model fitting method, and obtaining rebuilt critical dimension (CD?) values, according to relative error between CD? and CD, dividing the rebuilt critical dimension (CD?) values into scenes and the number of the scenes is A; S04: calculating components and corresponding residuals of the test points in each of the scenes under a reference system corresponding to a correction model by parameter estimation; S05: modifying machine parameters and masks by the correction model according to above calculation results.
