It is incredibly expensive to breed, train, and place a working guide dog; costs are tens of thousands of dollars for many organizations. During this training process, approximately 40% of canines are dropped due to medical, behavioral, or other reasons. Since guide dog schools do not have unlimited resources, they must focus on the most promising...
These proceedings contain oral and poster presentations from various experts on animal behaviour and animal welfare in veterinary medicine presented at the conference.
For thousands of years, humans have domesticated and trained dogs to perform tasks for them. Humans have developed areas of study, such as Applied Behavior Analysis, which aim to improve the training process. We introduce a semi-autonomous, canine-training system by combining existing research in Applied Behavior Analysis with computer systems cons...
3D sensing hardware, such as the Microsoft Kinect, allows new interaction paradigms that would be difficult to accomplish with traditional RGB cameras alone. One basic step in realizing these new methods of animal-computer interaction is posture and behavior detection and classification. In this paper, we present a system capable of identifying sta...
Hardware capable of 3D sensing, such as the Microsoft Kinect, has opened up new possibilities for low-cost computer vision applications. In this paper, we take the first steps towards unsupervised canine posture classification by presenting an algorithm to perform canine-background segmentation, using depth shadows and infrared data for increased a...
This paper describes a canine posture detection system composed of wearable sensors and instrumented devices that detect the postures sit, stand, and eat. The system consists of a customized harness outfitted with wearable Inertial Measurement Units (IMUs) and a base station for processing IMU data to classify canine postures. Research in operant c...
Training animals is a process that requires a significant investment of time and energy on the part of the trainer. One of the most basic training tasks is to train dogs to perform postures on cue. While it might be easy for a human trainer to see when an animal has performed the desired posture, it is much more difficult for a computer to determin...
One of the challenges to working with canines is that whereas humans are primarily vocal communicators, canines are primarily postural and behavioral communicators. It can take years to gain some level of proficiency at reading canine body language, even under the best of circumstances. In the case of guide dogs and visually-impaired handlers, this...
The authors introduce the fundamental building blocks for a cyber-enabled, computer-mediated communication platform to connect human and canine intelligence to achieve a new generation of Cyber-Enhanced Working Dog (CEWD). The use of monitoring technologies provides handlers with real-time information about the behavior and emotional state of their...
Our goal in creating the Graph SKetching tool, GSK, was to provide blind screen reader users with a means to create and access graphs as node-link diagrams and share them with sighted people in real-time. Through this effort, we hoped to better include blind people in computing and other STEM disciplines in which graphs are important. GSK proved ve...
Combinatorial graphs, often conveyed as node-link diagrams, figure prominently in Computer Science and other Science, Technology, Engineering, and Mathematics (STEM) disciplines. Unfortunately, they are most often inaccessible to blind students and professionals. This paper introduces GSK, a self-contained Graph SKetching tool that allows blind and...
As a research community, we currently know very little about the challenges faced by blind software developers. Without knowing what those challenges are, the community cannot effectively address these challenges. In this paper, we describe the first exploratory empirical study, where we conducted eight interviews with blind software developers to...
Traditionally node-link diagrams, also known as graphs, have been considered problematic for visually impaired and blind users. Our focus is to create a tool that allows a user to create and edit graphs without being able to see a screen or use a mouse. Professor Suzanne Balik and Sean Mealin collaborated on the creation of GSK, a software based to...

... Brugarolas et al. [9] developed a non-invasive wearable sensor system for measuring dogs' vital signs using electrocardiogram (ECG), photoplethysmogram (PPG), and inertial measurement units (IMU). In a longitudinal study of monitoring puppies' cardiac changes, Foster et al. [25] developed machine learning models for predicting puppies' Behavior Checklist (BCL) scores (including changes in energy and smoothness of movement, vocalization, tongue flicking, use of coping strategies, body language, and changes in responsiveness to the handler), achieving up to 90% of accuracy. Weiss et al. [96] developed WagTag that infers three dog activity levels (i.e., walk, run, and minimal), and concluded that personal models for predicting activity levels are better than universal models. ...

... Dogs play a critical role in modern society and perform an array of functions from simple quality of life interactions such as companionship, to professionally trained operations such as herding livestock; detecting drugs, explosives, and pests; and aiding in search and rescue (SAR) applications. A number of studies in the literature show that monitoring physiological signals (e.g., heart rate, heart rate variability) and behavioral indicators (e.g., activity levels, postures and body movement) not only provide insight into the physical and emotional health and welfare of the dogs, but also allow for computer-assisted training approaches [1][2][3][4][5][6][7]. Enabling such new information channels and decision-making capabilities during human and dog interactions through quantitative monitoring of dogs also allow for dog-machine or dog-robot interfaces [8][9][10][11][12][13]. ...
... En este sentido, se expone una revisión de los dispositivos empleados y algunos de los efectos más significativos en el comportamiento de perros dedicados a labores de seguridad y defensa. Así mismo, en la revisión se encuentran avances interesantes en la construcción de dispositivos destinados al adiestramiento canino, entre estos el desarrollado por Majikes et al. (2017), quienes presentan un sistema semiautónomo, el cual sirve para controlar los estímulos mediante la combinación de elementos de hardware, software, audio y ayudas visuales; con capacidad para entrenar de manera autónoma al animal para que ejecute un comportamiento específico cuando se le dé la instrucción. Para lograrlo, se apoyan en el condicionamiento operante utilizando la luz y el sonido como estímulos discriminativos, contribuyendo de forma similar a la que realiza un entrenador profesional. ...
... Moreover, canine units may also be useful to perform the task of obtaining maps of the area of interest [26], though harness-mounted cameras present some drawbacks, because of rapid movements of the dog [27]. In addition, canine units have already been proposed for the deployment of robots in emergency scenarios [28] and rescue dogs are often considered to be part of a biological SAR robot system [29], but integration of canine agents has attracted less research resources than robots, as they add constraints to the deployment [30]. As a matter of fact, the high mobility of rescue dogs usually makes it difficult to ensure coverage. ...
... In our prior work, we examined the benefits and limitations of various on-and offbody sensing of behavioral, environmental and physiological parameters for working dog applications [9,11,14,15,[17][18][19][20][21][22][23]. The major challenge is the difficulty of monitoring dogs' maximum heart rate during intense exercise due to excessive motion artifacts. ...
