Animation is useful in user interfaces, especially for representing dynamic features. However, it is often difficult and laborious to create animation in an existing user interface environment. In this research, we extend our bi-directional translation model to deal with animations. The new model incorporates the notion of time, and includes operations defined for each representation in the mod...

An efficient algorithm for enumerating a sequence of all elements in (Zn) k in a special order is presented. The sequence enumerated is called the (n,k)-Gray code. It has the property that each pair of adjacent elements differs in only one digit and the difference is either +1 or −1. This sequence can be efficiently applied to calculation of the weight polynomial of a group code. We also show t...

The Tower of Hanoi problem is generalized in such a way that the pegs are located at the vertices of a directed graph G, and moves of disks may be made only along edges of G. Leiss obtained a complete characterization of graphs in which arbitrarily many disks can be moved from the source vertex S to the destination vertex D. Here we consider graphs which do not satisfy this characterization; he...

Where do the predicates in a game ontology come from? We use RGBD vision to learn a) the spatial structure of a board, and b) the number of parameters in a move or transition. These are used to define state-transition predicates for a logical description of each game state. Given a set of videos for a game, we use an improved 3D multi-object tracking to obtain the positions of each piece in gam...

Two experiments using two isomorphs of the Tower of Hanoi show that participants increase the amount of planning they do as they learn that it increases problem solving efficiency. In addition, competition among different approaches emerged as participants gained more experience with the task, with an optimal strategy gradually replacing a less effective, though easier one. It is hypothesized t...

This paper presents the results from a qualitative case study of an auditory version of the game Towers of Hanoi. The goal of this study was to explore qualitative aspects of auditory direct manipulation and the subjective experience from playing the game. The results show that it is important to provide a way of focusing in the auditory space. Articulatory directness was also an important issu...

Abstract—Eutrophication of surface water is one of the most widespread environmental problems at present. Large number of pilgrims and tourists visit sacred artificial tank known as “Brahma Sarover” located at Kurukshetra, India to take holy dip and perform religious ceremonies. The sources of pollutants include impurities in feed water, mass bathing, religious offerings and windblown particula...
