A Framework for Efficient Development and Debugging of Role-Playing Agents with Large Language Models

We propose a framework that leverages large language models (LLMs) to semi-automate the development and debugging of role-playing agents, reducing the need for extensive manual effort. Role-playing agents powered by LLMs offer scalable solutions that enhance communication and interaction in various applications, such…

User-Guided Correction of Reconstruction Errors in Structure-from-Motion

We propose a user-guided method to correct reconstruction errors in Structure-from-Motion (SfM) processes. SfM takes a set of camera images as input and then estimates the cameras' poses and three-dimensional point clouds based on keypoint matching. However, scenes with repetitive or similar structures often result in…

VocabEncounter: NMT-powered Vocabulary Learning by Presenting Computer-Generated Usages of Foreign Words into Users' Daily Lives

We demonstrate that recent natural language processing (NLP) techniques introduce a new paradigm of vocabulary learning that benefits from both micro and usage-based learning by generating and presenting the usages of foreign words based on the learner's context. Then, without allocating dedicated time for studying, t…

Interactive Hyperparameter Optimization with Paintable Timelines

We propose a method to integrate more interactivity into automatic hyperparameter optimization systems to leverage the user's prior knowledge on parameter distribution. In our method, the user continuously observes automatic optimization's progress and dynamically specifies where to search in the parameter space. We p…

Phonetroller: Visual Representations of Fingers for Precise Touch Input when using a Phone in VR

Smartphone touch screens are potentially attractive for interaction in virtual reality (VR). However, the user cannot see the phone or their hands in a fully immersive VR setting, impeding their ability for precise touch input. We propose mounting a mirror above the phone screen such that the front-facing camera captu…

PenSight: Enhanced Interaction with a Pen-Top Camera

We propose mounting a downward-facing camera above the top end of a digital tablet pen. This creates a unique and practical viewing angle for capturing the pen-holding hand and the immediate surroundings which can include the other hand. The fabrication of a prototype device is described and the enabled interaction de…

Unimanual Pen+Touch Input Using Variations of Precision Grip Postures

We introduce a new pen input space by forming postures with the same hand that also grips the pen while writing, drawing, or selecting. The postures contact the multitouch surface around the pen to enable detection without special sensors. A formative study investigates the effectiveness, accuracy, and comfort of 33 c…
