ZeroTouch (ZT) is a unique optical sensing technique and architecture that allows precision
sensing of hands, fingers, and other objects within a constrained 2-dimensional plane …

With the omnipresence of computing devices in our daily lives, interests in ubiquitous
computing interfaces have grown. In response to this, various studies have introduced on …

Frustrated total internal reflection (FTIR) imaging is widely applied in various touch-sensing
systems. However, vision-based touch sensing has structural constraints, and the system …

Driven to create intuitive computing interfaces throughout our everyday space, various state-
of-the-art technologies have been proposed for near-surface localization of a user's finger …

We introduce UnicrePaint, a digital painting system that allows the user to paint with physical
objects by acquiring three parameters from the interacting object: the form, the color pattern …

As various computing devices, such as smartphones, IoT devices, smart speakers etc,
becomes omnipresent in our daily lives, interest in ubiquitous computing interfaces is …

This thesis presents systems and methods for real-time multiple-view and depth-based
optical tracking for specific human-computer interaction and smart environment applications …

This paper presents a technique for the construction of an elastic touch panel using silicone
rubber. The technique is similar to that of the frustrated total internal reflection-based method …

We applied a computer vision based method and developed multi-touch technology to be
adopted in various display types. In the selected design, multiple cameras are placed on the …

In this paper, we propose a method that estimates contact force to hard surface from a single
visual image of a finger by using a neural network. In general, it is hard to estimate applied …
