Object-Based Benefits Without Object-Based Representations

Abstract: Influential theories of visual working memory have proposed that the basic units of memory are integrated object representations. Key support for this proposal is provided by the same object benefit: It is easier to remember multiple features of a single object than the same set of features distributed across multiple objects. Here, we replicate the object benefit but demonstrate that features are not stored as single, integrated representations. Specifically, participants could remember 10 features better when arranged in 5 objects compared to 10 objects, yet memory for one object feature was largely independent of memory for the other object feature. These results rule out the possibility that integrated representations drive the object benefit and require a revision of the concept of object-based memory representations. We propose that working memory is object-based in regard to the factors that enhance performance but feature based in regard to the level of representational failure.

Manipulation-based active search for occluded objects

Abstract: Object search is an integral part of daily life, and in the quest for competent mobile manipulation robots it is an unavoidable problem. Previous approaches focus on cases where objects are in unknown rooms but lying out in the open, which transforms object search into active visual search. However, in real life, objects may be in the back of cupboards occluded by other objects, instead of conveniently on a table by themselves. Extending search to occluded objects requires a more precise model and tighter integration with manipulation. We present a novel generative model for representing container contents by using object co-occurrence information and spatial constraints. Given a target object, a planner uses the model to guide an agent to explore containers where the target is likely, potentially needing to move occluding objects to enable further perception. We demonstrate the model on simulated domains and a detailed simulation involving a PR2 robot.

Extensible object-modelling mechanism

Abstract: An XML management system, comprising: a repository configured to store a manipulable object model capable of representing metadata about objects in a user's computing environment; user accessible means for manipulating said object model to modify properties of objects thus represented; and means for extending said object model to handle a new type of object by automatically generating descendent class(es) that are able to handle the new object within the object model and incorporating them into an XML management system runtime environment for participation in the object modelling process.

Using subject-oriented programming to overcome common problems in object-oriented software development/evolution

Abstract: This note presents an overview of this ICSE ‘99 tutorial.

Portlet template based on a state design pattern

Abstract: A method for designing object-oriented software for implementing portlets, and an associated computer system and computer program product. The portlets are available to a user of the software who clicks on a link of a first page to identify an action object of an Action class and a state object of a State class. The software includes the State class, the Action class, and program code. The State class includes a method for displaying a view of a page. The Action class includes an actionPerformed method for performing an action and a setState method for setting the state object into the session. The program code is adapted to execute: the actionPerformed method of the action object to perform the action; the setState method of the action object to set the state object; and the method of the state object to display a view of a second page.
