Bridging User Context and Design Models to Build Adaptive User Interfaces [chapter]

Mladjan Jovanovic, Dusan Starcevic, Zoran Jovanovic
2014 Lecture Notes in Computer Science  
The framework has been used in the data visualization domain, particularly in the design of the software instrument table for UAV (Unmanned Aerial Vehicle) that takes into account user context, namely  ...  human perceptual abilities.  ...  The framework was used to build adaptive user interfaces for data visualization domain in the context of human perceptual abilities.  ...

Learning Abstract Concept Embeddings from Multi-Modal Data: Since You Probably Can't See What I Mean

Felix Hill, Anna Korhonen
2014 Proceedings of the 2014 Conference on Empirical Methods in Natural Language Processing (EMNLP)  
Our architecture outperforms previous approaches in combining input from distinct modalities, and propagates perceptual information on concrete concepts to abstract concepts more effectively than alternatives  ...  Models that acquire semantic representations from both linguistic and perceptual input are of interest to researchers in NLP because of the obvious parallels with human language learning.  ...  For target words w n in the domain of P (concrete concepts), the model updates its representations based on corpus context words w n±i , then on words p w n±i in perceptual pseudo-sentences.  ...

Referring to the recently seen: reference and perceptual memory in situated dialog [article]

John D. Kelleher, Simon Dobnik
2019 arXiv   pre-print
This paper, by contrast, opens up the question of how perceptual memory and linguistic references interact, and the challenges that this poses to computational models of perceptually grounded dialog.  ...  Furthermore, the similarity in the encodings in the perceptual memory and discourse context model facilitates reference resolution, which entails copying, restructuring, and inserting of a reference domains  ...  perceptual context.  ...

Postfiltering with Complex Spectral Correlations for Speech and Audio Coding

Sneha Das, Tom Bäckström
2018 Interspeech 2018  
To improve performance, many codecs use pre-and post-filtering techniques to reduce the perceptual effect of quantization-noise.  ...  Since conventional speech codecs cannot transmit information with temporal dependencies as transmission errors could result in severe error propagation, we model the correlation offline and employ them  ...  The windowed signals are then transformed to the frequency domain. Since the enhancement is applied in the perceptual domain, we also model the speech in the perceptual domain.  ...

Cognitive cooperation through visual interaction

The model is used to determine when it would be cognitively effective to afford assistance.  ...  User interface design theories must be utilized in order to effectively map the output representation(s) onto the desired view of the problem-solving context.  ...

Predictive coding? Yes, but from what source?

Gregory Hickok
2013 Behavioral and Brain Sciences  
Here I summarize the computational problem with motor prediction for perceptual processes and argue instead for a dual-stream model of predictive coding.  ...  AbstractThere is little doubt that predictive coding is an important mechanism in language processing–indeed, in information processing generally.  ...  like priming, context and top-down effects, and the like.  ...

Postfiltering Using Log-Magnitude Spectrum for Speech and Audio Coding

Sneha Das, Tom Bäckström
2018 Interspeech 2018  
In this paper, we propose a post-processing method based on modeling the inherent time-frequency correlation in the log-magnitude spectrum.  ...  Objective measures show an average improvement of 1.5 dB for input perceptual SNR in range 4 to 18 dB. The improvement is especially prominent in components which had been quantized to zero.  ...  In addition, the approach aids in reducing the perceptual effect of distortions caused by sparsity on the signal.  ...

Context-Sensitive Computational Mechanisms of Decision Making

Manisha Chawla, Krishna P Miyapuram
2018 Journal of Experimental Neuroscience  
This review presents research from value-based, perceptual, and social decision-making domains, so far studied using isolated paradigms and their corresponding computational models.  ...  Second, given that both our perception and valuation are influenced by the surrounding context, we suggest the integration of different types of information in decision making could be done by studying  ...  These context-sensitive mechanisms are similar to widely known simultaneous and successive contrast effects in vision.  ...

Visual Embedding: A Model for Visualization

Cagatay Demiralp, Carlos E. Scheidegger, Gordon L. Kindlmann, David H. Laidlaw, Jeffrey Heer
2014 IEEE Computer Graphics and Applications  
A visual embedding is a function from data points to a space of visual primitives that measurably preserves structures in the data (domain) within the mapped perceptual space (range).  ...  Visual embedding can serve as both a generative and an evaluative model.  ...  Visualizations live in context; estimated perceptual distances with crowdsourcing cannot capture all the perceptual interactions of every context.  ...

A Mechanistic Approach to Cross-Domain Perceptual Narrowing in the First Year of Life

Hillary Hadley, Gwyneth Rost, Eswen Fava, Lisa Scott
2014 Brain Sciences  
However, the mechanisms underlying perceptual development during this time, and whether they are shared across domains, remain largely unknown.  ...  In addition, we propose word learning as an important top-down factor that shapes tuning in both the speech and face domains, leading to similar observed developmental trajectories across modalities.  ...  tuning effects are observed across domains.  ...

On reconstruction of task context after interruption

Dario D. Salvucci
2010 Proceedings of the 28th international conference on Human factors in computing systems - CHI '10  
In contrast, for many task domains, resumption can more accurately be represented in terms of a process of reconstruction-perceptual re-encoding of the information necessary to perform the task.  ...  The paper also describes computational models of two sample task domains that illustrate the sometimes complex relationship between reconstruction and more general human cognitive, perceptual, and motor  ...  The theoretical framework here, grounded in ACT-R theory, provides a way of reasoning about task context in terms of problem state and of specifying reconstruction processes in terms of cognitive, perceptual  ...

JND mask adaptation for wavelet domain watermarking

Mohamed Bouchakour, Guillaume Jeannic, Florent Autrusseau
2008 2008 IEEE International Conference on Multimedia and Expo  
The Fourier transform is particularly adapted to the Human Visual System (HVS) modeling. In this work, we evaluate the usability of the JND mask in the wavelet domain.  ...  The use of the mask in the DWT domain involves some approximations. We will see here that the HVS decomposition and the wavelet decomposition do not perfectly fit altogether.  ...  Perceptual modeling is very important in watermarking context, it is in fact crucial to embed the watermark in the perceptually significant image areas, otherwise, the watermark wouldn't resist to lossy  ...
