Synthetic personae and data powered by artificial intelligence (AI) are emerging in many HCI areas, including education and training, gaming, and piloting research studies. Recently, Large Language Models (LLMs) have shown promise for synthetic AI ...

As design researchers, we often make use of sketching in our work. What happens when we explore the edges of this practice in order to focus on sketching as a collective making site? We address this question through a series of workshops designed to ...

Shadow puppetry, a culturally rich storytelling art, faces challenges transitioning to the digital realm. Creators in the early design phase struggle with crafting intricate patterns, textures, and basic animations while adhering to stylistic conventions ...

We introduce DrawTalking, an approach to building and controlling interactive worlds by sketching and speaking while telling stories. It emphasizes user control and flexibility, and gives programming-like capability without requiring code. An early open-...

In recent years, graph neural networks (GNNs) have emerged as a potent tool for learning on graph-structured data and won fruitful successes in varied fields. The majority of GNNs follow the message-passing paradigm, where representations of each node ...

Maximum inner product search (MIPS) over dense and sparse vectors have progressed independently in a bifurcated literature for decades; the latter is better known as top-\(k\) retrieval in Information Retrieval. This duality exists because sparse and ...

Motor skills are crucial for young children’s academic and social growth, making early detection of motor skill delays critical. Although the current work in digital assessments and tablets in classrooms offer accessible diagnostic tools, they only ...

This short article is a description of the invited talk on matrix approximations that I will give at PODS, 2024.

With the increasing rate of data generated by critical systems, estimating functions on streaming data has become essential. This demand has driven numerous advancements in algorithms designed to efficiently query and analyze one or more data streams ...

Estimating the ε-approximate quantiles or ranks of a stream is a fundamental task in data monitoring. Given a stream x_1,..., x_n from a universe \mathcalU with total order, an additive-error quantile sketch \mathcalM allows us to approximate the rank of ...

In this paper, we study streaming algorithms that minimize the number of changes made to their internal state (i.e., memory contents). While the design of streaming algorithms typically focuses on minimizing space and update time, these metrics fail to ...

We introduce DrawTalking, a prototype system enabling an approach that empowers users to build interactive worlds by sketching and speaking. The approach emphasizes user control and flexibility, and gives programming-like capability without requiring ...

Sketching precisely in Virtual Reality (VR) is challenging due to the lack of a physical surface for users to lean on, feel the contact and the movement of the pen, and constrain the pen movement. Using physical surface interfaces, such as a touch ...

Shadow puppetry is a cultural heritage with thousands of years of history, and its digital form has become a popular style in modern artistic creation. Creating high-quality shadow puppet works is often challenging. We present "ShadowMaker," an ...

When thinking of arts in HCI, one might be tempted to keep one’s eyes focused on prominent realms such as sketching for UX Design and design probes from participants. A closer look shows that practices go beyond this, involving a variety of arts-based ...

Synthetic personae and data powered by artificial intelligence (AI) are emerging in many HCI areas, including education and training, gaming, and piloting research studies. Recently, Large Language Models (LLMs) have shown promise for synthetic AI ...

The ability to sketch is a gift to yourself and others. It transcends disciplines by its nature as a tool for communication, but is of particular use within HCI and UX where it also enables the design of interactions. Sketching is a low-fidelity, ...

InkBrush is a new sketch-based 3D drawing tool for creating 3D ink paintings using free-form 3D ink strokes. It offers a digital calligraphy brush and various editing tools to generate realistic ink-like brush strokes with attributes like hairy edges, ...

Block-based programming effectively supports processes based on the syntactic and conceptual knowledge of programming; however, its effectiveness is limited to processes that require strategic knowledge. To resolve the problem, we present Sketchnote, ...

As a stylized representation of traditional painting art, ink painting has been widely used in most of Asian countries. Art creations with ink painting strokes in 3D space have shown potential in animation and games. We propose a sketch-based authoring ...
