Network-linked interactive three-dimensional composition and display of saleable objects in situ in viewer-selected scenes for purposes of object promotion and procurement, and generation of object advertisements

Abstract: A design professional such as an interior designer, furniture sales associate or advertising designer or a consumer running a program at a client computer (i) interactively selects or specifies a background scene and furnishings or other objects, (ii) interactively previews these objects in a small low-quality perspective view image of the scene, and then (iii) utilizing the world wide web transmits the scene file to a server computer, (iv) this server then renders a typically larger high-quality version of the previewed scene, utilizing high-resolution objects to replace the stand-in objects used to render the preview image on the client computer, (v) which high-quality image is returned to the client computer for viewing. 3 D models and related textures and maps are built for each object to be depicted in the virtual scenes. For transmission efficiency, the scene file transmitted to the server may contain only the name of stand-in models and textures used in the scene, rather than the actual geometry and maps, if these reside on the server. Images so produced serve to promote the sale of visually-attractive goods depicted by providing the designer and consumer with in-context visualization.

Modeling concepts for VLSI CAD objects

Abstract: VLSI CAD applications deal with design objects that have an interface description and an implementation description. Versions of design objects have a common interface but differ in their implementations. A molecular object is a modeling construct which enables a database entity to be represented by two sets of heterogeneous records, one set describes the object's interface and the other describes its implementation. Thus a reasonable starting point for modeling design objects is to begin with the concept of molecular objects.In this paper, we identify modeling concepts that are fundamental to capturing the semantics of VLSI CAD design objects and versions in terms of molecular objects. A provisional set of user operations on design objects, consistent with these modeling concepts, is also defined. The modeling framework that we present has been found useful for investigating physical storage techniques and change notification problems in version control.

Coordinated Dynamic Hybrid Position/Force Control for Multiple Robot Manipulators Handling One Constrained Object

Abstract: In coordinated manipulation of a single object using multiple robot arms or a multifingered robot hand, simultaneous control of the object motion and of the internal force exerted by arms or fingers on the object is required. Furthermore, in the case where the motion of the object is constrained in some direc tions because of contact with its environment, control of the constraint force also becomes necessary. In this article, we pro pose a coordinated dynamic hybrid control method for multiple robotic mechanisms. The method takes the manipulator dynam ics and object dynamics into consideration and controls the motion of an object under constraint as well as the constraint force and the internal force. The motion control of an object in free space can be treated as a special case within the same formulation. A unified description for accommodating various grasp types is used. Several experimental results that show the validity of the proposed approach are presented. The results of this article will be use...

Virtual objects for building a community in a virtual world

Abstract: A virtual world computer process includes portable virtual token objects that can be used by on-line users of the virtual world to facilitate exchange of goods and services within the virtual world. In particular, client-server computer processes are provided for the virtual world that allow on-line users to conduct activities within the virtual world including getting, putting, giving, and receiving portable virtual token objects as well as other portable virtual objects. Each on-line user is represented in the graphic user interface by a virtual avatar object. Token objects are put into circulation by virtual ATM objects. A virtual ATM object allows a user to obtain a balance, deposit tokens, and withdraw tokens. A vendroid object is an object that sells portable virtual items in exchange for tokens deposited by avatars. Different virtual items have different values, and vendroids do not all have the same virtual items for sale. In the virtual world, a lurker is represented in a locale by a ghost object. An icon is present, i.e, an eye-the-sky, in a locale, whenever a ghost object, or ghost objects are present. Ghost objects have anonymity, i.e. their names are not known to avatars of the locale, and have limited interaction choices. A ghost object cannot talk or think to other avatars. A ghost object retains the ability to transmit private “ESP” messages to other avatars.
