This paper presents the results of an experiment in which students are asked to reposition rectangular shapes in a window in two cases: when they are or they are not told that the window should be considered the configuration of a graphical user interface (GUI). The main aim of the research is to investigate if users have different aesthetical preferences in the two distinct cases. Other goals ...

Given an observed point pattern in a window W0 ⊂ R we address the following two questions: How can one extend in a ‘reasonable way’ the pattern to a larger window W ⊃ W0? Can one predict possible gaps in the observed point configuration where points were ‘expected’ but somehow failed to realise? By assuming that the point pattern is an observed part of a realisation of a non-homogeneous Poisson...

EEG signals recorded from scalp contain useful information about the activity of a large number of neurons. Signal processing is needed to extract this information from the EEG signal. Here we study the effects of configurations of Short Time Fourier Transform (STFT) to determine how the parameters of STFT affect spectral estimations of the mean and relative power in beta and gamma frequency ba...

The Video Window is a video screen hanging next to a window on my bedroom wall, showing the image from a camera mounted to show the skyline from outside that same window. This paper describes the appeal of living with such a system, and the intermingled aesthetic, utilitarian and practical issues involved in its creation and the experience it offers. About six months ago 1 , I mounted a small v...

Existing user interfaces for the configuration of large shared displays with multiple inputs and outputs usually do not allow users easy and direct configuration of the display’s properties such as window arrangement or scaling. To address this problem, we are exploring a gesture-based technique for manipulating display windows on shared display systems. To aid target selection under noisy trac...

The effects of spatial attention and part-whole configuration on recognition of repeated objects were investigated with behavioral and event-related potential (ERP) measures. Short-term repetition effects were measured for probe objects as a function of whether a preceding prime object was shown as an intact image or coarsely scrambled (split into two halves) and whether or not it had been atte...

PAN is a process based Prolog system running in a distributed manner on the nodes of a virtual multiprocessor. It was designed to be a general purpose parallel logic programming system that would be resilient to software and hardware evolution. Programs can explicitly control parallelism through passing general terms synchronously or asynchronously among PAN’s Prolog engines. Alternatively seve...

The dynamic window approach is a well known navigation scheme developed by Fox et. al. [1] and extended by Brock and Khatib [2]. It is safe by construction and has been shown to perform very efficiently in experimental setups. However, one can construct examples where the proposed scheme fails to attain the goal configuration. What has been lacking is a theoretical treatment of the algorithm’s ...
