Project Description

Web-based application aimed at creating and debugging data analysis and machine learning pipelines. The user imports his data and starts with a specific goal (eg. Understanding the structure of unlabeled data, classifying data, predicting future values, ...). A visual programming interface and a suggestion engine help the user quickly build and run their pipeline, of which they can track results and performance. The tool enables multiscale programming, allowing users to modify existing code blocks or create custom ones. Suggestions are generated based on the success of previous pipelines having similar input data and goal, created by several data scientists.

Project Description

Detecting motor activities from sensor datasets is becoming increasingly common in a wide range of applications with the rapid commoditization of wearable sensors. To detect activities, data scientists iteratively experiment with different classifiers before deciding on a single model. Evaluating, comparing, and reasoning about prediction results of alternative classifiers is a crucial step in the process of iterative model development. However, standard aggregate performance metrics (such as accuracy score) and textual display of individual event sequences have limited granularity and scalability to effectively perform this critical step. <br/> To ameliorate these limitations, we introduce Track Xplorer, an interactive visualization system to query, analyze and compare the classification output of activity detection in multi-sensor data. Track Xplorer visualizes the results of different classifiers as well as the ground truth labels and the video of activities as temporally-aligned linear tracks. Through coordinated track visualizations, Track Xplorer enables users to interactively explore and compare the results of different classifiers, assess their accuracy with respect to the ground truth labels and video. Users can brush arbitrary regions of any classifier track, zoom in and out with ease, and playback the corresponding video segment to contextualize the performance of the classifier within the selected region. Track Xplorer also contributes an algebra over track representations to filter, compose, and compare classification outputs, enabling users to effectively reason about the performance of classifiers. We demonstrate how our tool helps data scientists debug misclassifications and improve the prediction performance in developing activity classifiers for real-world, multi-sensor data gathered from Parkinson's patients.

Project Description

Detecting motor activity in temporal data collected by sensors is an important task in wearable sensor applications. Datasets of sensor data often contain limited information about the usage context of the devices and video validation is not always possible, causing a lack of interpretable ground-truth labels. This lack of context can limit the understanding of sensors data, causing data scientists to make incorrect assumptions or to run machine learning algorithms as black-box models. We introduce BlueSky Wanderer, an interactive visual analysis tool for running classification algorithms on live-streaming sensor data. Our system provides visual and quantitative methods to iteratively reason on classification performance and to develop better intuition about structured patterns in data. In particular, BlueSky Wanderer enables quick debugging, validation, and dynamic fine-tuning of classification models for activity recognition. We use a case study to demonstrate how our approach can improve the development of a set of motion classifiers for monitoring the symptoms of Parkinson's disease.

Project Description

Dimensionality reduction is a common method for analyzing and visualizing high-dimensional data across domains. Dimensionality-reduction algorithms involve complex optimizations and the reduced dimensions computed by these algorithms generally lack clear relation to the initial data dimensions. Therefore, interpreting and reasoning about dimensionality reductions can be difficult. In this work, we introduce two interaction techniques, forward projection and backward projection}, for reasoning dynamically about scatter plots of dimensionally reduced data. We also contribute two related visualization techniques, prolines and feasibility map to facilitate and enrich the effective use of the proposed interactions, which we integrate in a new tool called Praxis. To evaluate our techniques, we first analyze their time and accuracy performance across varying sample and dimension sizes. We then conduct a user study in which twelve data scientists use Praxis so as to assess the usefulness of the techniques in performing exploratory data analysis tasks. Results suggest that our visual interactions are intuitive and effective for exploring dimensionality reductions and generating hypotheses about the underlying data.

Project Description

This is a room-scale virtual reality game for the HTC Vive where players motion controllers to fire a slingshot at multi-colored targets (low poly 3D shapes). Players wear an EEG brain-sensing headband that makes time slow down as the brain reaches a mindful state. Slowing time makes targets easier to shoot and creates a feedback loop that promotes mindfulness. Target colors flash and disappear, which requires working memory to remember which targets to shoot. Players progress through levels unlocking new game mechanics such as new firing modes and target types.

Features

• Virtual Reality videogame for HTC Vive
• Control of time through real-time analysis EEG data
• Dynamic environment changing based on user's emotions

Project Description

In this document we present a novel approach to the design of mixed reality (MR) applications, which combines elements from markerless and locationbased augmented reality in order to explore new types of interaction, leveraging a spatial representation of virtual content. In particular, we propose a method for developing both a mobile application, that can be used by people to see augmented content in the real world, and an editor application, which can be used to design and create MR experiences. In our presentation, we deal with the currently available mobile technologies and we discuss the integration of dierent techniques in order to improve tracking within the context of our location-based approach, in which every content has a dened position in real space. After discussing the advantages and the new interaction possibilities enabled by our method, we dene the requirements for a MR authoring tool and we propose our own implementation, aimed at decoupling the editing process from the use of tracking techniques. We particularly focus on the mapping between real-world and virtual coordinates and on the possibilities enabled by real-time editing, which allows the designer to remotely preview the MR experience and to interact with users. We demonstrate the usefulness of our method by presenting two applications developed with our approach and by analyzing some real-world examples.

• Introduction of an intelligent "triple camera approach", merging pattern recognition, SLAM tecniques and mobile sensors
• "Mapping between the two worlds", enabling a continuous, absolute camera pose estimation

Project Description

With the advent of new hardware and software technologies, virtual reality has gained a significant momentum recently. VR design tools, such as game engines, have become much more accessible and are being used in a variety of applications ranging from physical rehabilitation to immersive art. These tools, however, offer a limited set of tools for audio processing in 3D virtual environments. Furthermore, they are platform-dependent due to performance requirements and feature separate editing and rendering modes, which can be limiting for sonic VR implementations. To address these, we introduce a novel webbased system that makes it possible to compose and control the binaural rendering of a dynamic open-space auditory scene. Developed within a framework of well-established theories on sound, our system enables a highly detailed bottom-up construction of interactive virtual soundscapes by offering tools to populate navigable sound fields at various scales (i.e. from sound cones to 3D sound objects to sound zones). Based on modern web technologies, such as WebGL and Web Audio, our system operates on both desktop computers and mobile devices. This enables our system to be used for a variety of mixed reality applications, including those where users can simultaneously manipulate and experience a virtual soundscape.
