OpenCD: Empowering Diagnosis of Children's Mathematical Cognition through Open-ended Multimodal Tasks

Assessing children’s cognitive development in early mathematics is vital for effective teaching. Compared to closed-ended questions, which may fail to capture nuanced developmental spectrum, open-ended elicitation tasks (e.g., asking students to manipulate objects or draw to represent numbers) serve as a promising app…

EchoMind: Supporting Real-time Complex Problem Discussions through Human-AI Collaborative Facilitation

Teams often engage in group discussions to leverage collective intelligence when solving complex problems. However, in real-time discussions, such as face-to-face meetings, participants frequently struggle with managing diverse perspectives and structuring content, which can lead to unproductive outcomes like forgetfu…

Investigating Context-Aware Collaborative Text Entry on Smartphones using Large Language Models

Text entry is a fundamental and ubiquitous task, but users often face challenges such as situational impairments or difficulties in sentence formulation. Motivated by this, we explore the potential of large language models (LLMs) to assist with text entry in real-world contexts. We propose a collaborative smartphone-b…

From Gap to Synergy: Enhancing Contextual Understanding through Human-Machine Collaboration in Personalized Systems

This paper presents LangAware, a collaborative approach for constructing personalized context for context-aware applications. The need for personalization arises due to significant variations in context between individuals based on scenarios, devices, and preferences. However, there is often a notable gap between huma…

BiTipText: Bimanual Eyes-Free Text Entry on a Fingertip Keyboard

We present a bimanual text input method on a miniature fingertip keyboard, that invisibly resides on the first segment of a user's index finger on both hands. Text entry can be carried out using the thumb-tip to tap the tip of the index finger. The design of our keyboard layout followed an iterative process, where we…
