Abstract: An information processing apparatus includes an area environment load calculation module, a user environment load calculation module, a user improvement environment load calculation module, a comparison module and an output module. The area environment load calculation module calculates an environment load in an area in a room. The user environment load calculation module calculates an environment load of each user staying in the area based on the environment load calculated by the area environment load calculation module. The user improvement environment load calculation module calculates, based on a policy set in advance, an environment load of each user when the policy is adopted. The comparison module compares the environment load calculated by the user environment load calculation module with the environment load calculated by the user improvement environment load calculation module. The output module outputs the policy based on the number of users.
Abstract: Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size.

Abstract: An image of a paginated document is zoned to identify text zones. First-pass character recognition is performed on the text zones to generate textual content corresponding to the paginated document. The image of the paginated document is re-zoned based on the textual content to identify one or more new text zones. Second-pass character recognition is performed on at least the new text zones to generate updated textual content corresponding to the paginated document.
Abstract: Fixing devices for fixing marking material to a web, printing apparatuses and methods of fixing marking material to a web are provided. An exemplary embodiment of the fixing devices includes a first roll including a heated outer surface; a second roll forming a fixing nip with the outer surface of the first roll at which a continuous web on which marking material is disposed is received; a third roll positioned to contact the web prior to entering the fixing nip; and an adjustment mechanism connected to the third roll. The adjustment mechanism is operable to move the third roll to vary a wrap length of the web contacting the outer surface of the first roll upstream from the fixing nip to control pre-heating of the web and marking material by contact with the outer surface prior to entering the fixing nip. The first roll and second roll are operable to apply heat and pressure to the pre-heated web and marking material at the fixing nip to fix the marking material to the web.

Abstract: Systems and methods provide for mixed use of physical documents and a computer, and more specifically provide for detailed interactions with fine-grained content of physical documents that are integrated with operations on a computer to provide for improved user interactions between the physical documents and the computer. The system includes a camera which processes the physical documents and detects gestures made by a user with respect to the physical documents, a projector which provides visual feedback on the physical document, and a computer with a display to coordinate the interactions of the user with the computer and the interactions of the user with the physical document. The system, which can be portable, is capable of detecting interactions with fine-grained content of the physical document and translating interactions at the physical document with the computer display, and vice versa.

Abstract: An information processing apparatus includes an entrance and exit detection module, an organization information obtaining module, a user number calculation module, a seat determination module and a presentation module. The entrance and exit detection module detects a user's entrance and exit to and from a room. The organization information obtaining module obtains user information representative of a user belonging to an organization using the room by using organization user information storing organization information representative of the organization and the user information representative of the user belonging to the organization. The user number calculation module calculates the number of users of the organization using the room. The seat determination module associates with each other the organization information representative of the organization and seat information representative of seats in the room, and determines a seat for the user whose entrance is detected.
