This paper describes Familiar, a domain-independent programming by demonstration system for automating iterative tasks in existing, unmodified applications on a popular commercial platform. Familiar is domainindependent in an immediate and practical sense: it requires no domain knowledge from the developer and works immediately with new applications as soon as they are installed. Based on the A...

One of the most natural ways to acquire procedural knowledge is to watch somebody performing a number of actions and try to abstract this observed action sequence in order to make it applicable to a wider range of situations. This abstraction process can be significantly facilitated if the performing agent gives additional hints e.g. on the reasons for choosing a particular action or dealing wi...

For every v ≡ 5 (mod 6) there exists a pairwise balanced design (PBD) of order v with exactly one block of size 5 and the rest of size 3. We will refer to such a PBD as a PBD(5∗, 3). A flower in a PBD(5∗, 3) is the set of all blocks containing a given point. If (S,B) is a PBD(5∗, 3) and F is a flower, we will write F ∗ to indicate that F contains the block of size 5. The flower intersection pro...

Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until now, they are limited to scenarios with relatively small plastic deformation. In this work, we present a method for simulating deformable solids undergoing large plastic deform...

This Paper presents improvements done to a Programming by Demonstration(PbD)system in order to handle complex one and two hand manipulations. In order to do this, functional roles were added to the systems knowledge base. According to them a probability density function expressing the relationship between the manipulated objects has been set up. Since one object can fulfill several functional r...

We present a visual language that serves as a novel form of feedback in a Programming by Demonstration (PBD) interface. The language explicitly represents data, such as les, with unique icons and implicitly represents operations by changes to data icons, so that operations reeect the changes seen in the interface when executed. In addition, the language is used to provide feedback to the user b...

the purpose of the present study was to compare the effects of two methods of self-modeling and video demonstration of an expert on the acquisition and retention of volleyball serve skill. participants were 30 students (aged between 12 and 14) who were assigned into two homogeneous groups after the pretest. the self-modeling group (n = 15) watched their performances in the criterion task via a ...

purpose: the present study aims at comparing the impact of two teaching/learning approaches-self- directed/paced learning and lecture/demonstration-based instruction-on mastering psychomotor skills among nursing students. material & method: thirty nursing students were selected for the study. they filled out questionnaires indicating the demographic factor, and mean exam scores achieved in the ...

A pairwise balanced design is an ordered pair S,B , denoted PBD S,B , where S is a finite set of symbols, and B is a collection of subsets of S called blocks, such that each pair of distinct elements of S occurs together in exactly one block of B. Here |S| v is called the order of the PBD. Note that there is no condition on the size of the blocks in B. If all blocks are of the same size k, then...

Many iterative tasks in direct manipulation interfaces cannot be automated with standard application tools, forcing users to repeat the same interface actions again and again. We describe a domain-independent programming by demonstration system that learns iterative tasks in a range of widely-used applications on a popular computer platform. An evaluation showed that users are capable of using ...
