HCI for the deaf community: developing human-like avatars for sign language synthesis

With ever increasing computing power and advances in 3D animation technologies it is no surprise that 3D avatars for sign language (SL) generation are advancing too. Traditionally these avatars have been driven by somewhat expensive and inflexible motion capture technologies and perhaps this is the reason avatars do not feature in all but a few user interfaces (UIs). SL synthesis is a competing technology that is less costly, more versatile and may prove to be the answer to the current lack of access for the Deaf in HCI. This paper outlines the current state of the art in SL synthesis for HCI and how we propose to advance this by improving avatar quality and realism with a view to ameliorating communication and computer interaction for the Deaf community as part of a wider localisation project

Analyzing Coxsackievirus B3 Genomic RNA by Site Directed Mutagenesis and SHAPE Analysis

Virulent Coxsackievirus B3 (CVB3) is linked to myocarditis, pancreatitis, and type I diabetes. Avirulent CVB3 doesn’t cause disease. CVB3 possesses a positive, single-stranded ribonucleic acid (RNA) genome containing 7,400 nucleotides, organized into four sections: a 5’ untranslated region (5’ UTR), a single open reading frame, a 3’ untranslated region, and a poly-A tail. The 5’ UTR is 743 nucleotides divided into 7 domains. Mutations within the 5’ UTR can alter RNA structure, and thus alter virulence. Nucleotide associations responsible for higher level RNA folding patterns and structure haven’t been defined. We are investigating the 5’ UTR by selective 2’ hydroxyl acylation analyzed by primer extension (SHAPE) to learn about the flexibility of the RNA backbone, thus determining the relationship between RNA structure and virulence. New data generated through SHAPE will be compared to known models of CVB3. This will provide quantitative data regarding flexibility in the RNA structure. Previously, the virulent and avirulent strains were characterized by base-specific mutagenesis and the structure qualitatively analyzed. My work will determine the nucleotide associations responsible for virulence

Thresholds of territory, time, and intimacy

I began this author’s response sitting on a plush red and pink Chinese blanket; the familiar Himalaya was in view across the Indus River, in Ladakh which is now a Union Territory, not part of Jammu and Kashmir State (J&K) as it had been when I wrote the book. Intimate Geopolitics is the story of the embodied life of territory in this mountainous former kingdom on India’s contested northern borders with Pakistan and China. The book traces how the history of colonization and its post-independence reverberations set the stage for geopolitical life – for decisions about love, friendship, children, and intimate life to become a terrain on which geopolitical meaning is made

The impact of thiamin (B1) and its precursors on microzooplankton-phytoplankton interactions

Phytoplankton, marine microalgae that are the base of the oceanic food web, significantly influence the flow of essential nutrients throughout marine ecosystems. In particular, phytoplankton have been implicated in the cycling of the vitamin thiamin (B1) and its components 4-methyl-5-thiazoleethanol (HET) and 4-amino-5-hydroxymethyl-2-methylpyrimidine (HMP). These compounds are essential to many marine microbes but are found in relatively small concentrations (\u3c500 pM) throughout the earth’s oceans. Despite the importance of these vitamins in fueling marine microbial growth, very little is understood regarding their sources and sinks. To better understand the impacts of vitamins on phytoplankton growth and interactions with microzooplankton grazers, 20 dilution experiments spiked with additions of B1, HET, or HMP were conducted. These were performed across seasons, and examined changes not only in bulk chlorophyll concentration, but also in size-specific growth and grazing rates. No clear patterns in rate changes in response to additions of B1 or precursors were observed. Additionally, often vitamin addition resulted in compound-dependent significant changes in growth and loss rates. No significant changes in rates were found to correlate with starting phytoplankton abundance, suggesting that the composition of the starting phytoplankton community played a large role in mediating the response to vitamin addition relative to total abundance. Overall, these findings highlight the complexity and importance of understanding the sources and sinks of B1 and its components in the marine environment

Experience Bobo Experience

Experience Bobo Experience -by Sara Marie Smith (Artist Statements and Images of work) Spring 2018-CSUMB Undergraduate Capstone Project/ Visual Public Arts Department My Senior Capstone is about using inspirational wisdom from acknowledged sources to address the quandaries of our human experiences. I have chosen a cognitive clown, named Bobo, to investigate Henry David Thoreau, Jack Kerouac, and Allen Watts. Bobo, my character, goes on a journey of learning. Bobo is a line drawing, rendered in marker, with a circular head, two dot eyes, three puffs of hair with a clown smile and clown clothing. Experience Bobo Experience speaks to viewers who have struggled with adult situations of frustration, disillusionment, and spiritual fatigue and youth may be attracted to the joyous and playful aesthetic

Building a sign language corpus for use in machine translation

In recent years data-driven methods of machine translation (MT) have overtaken rule-based approaches as the predominant means of automatically translating between languages. A pre-requisite for such an approach is a parallel corpus of the source and target languages. Technological developments in sign language (SL) capturing, analysis and processing tools now mean that SL corpora are becoming increasingly available. With transcription and language analysis tools being mainly designed and used for linguistic purposes, we describe the process of creating a multimedia parallel corpus specifically for the purposes of English to Irish Sign Language (ISL) MT. As part of our larger project on localisation, our research is focussed on developing assistive technology for patients with limited English in the domain of healthcare. Focussing on the first point of contact a patient has with a GP’s office, the medical secretary, we sought to develop a corpus from the dialogue between the two parties when scheduling an appointment. Throughout the development process we have created one parallel corpus in six different modalities from this initial dialogue. In this paper we discuss the multi-stage process of the development of this parallel corpus as individual and interdependent entities, both for our own MT purposes and their usefulness in the wider MT and SL research domains
