Reading is a very common learning activity, a lot of people perform it everyday even while standing in the subway or waiting in the doctors office. However, we know little about our everyday reading habits, quantifying them enables us to get more insights about better language skills, more effective learning and ultimately critical thinking.

Facial expression is a powerful way for us to exchange information nonverbally. They can give us insights into how people feel and think. There are a number of works related to facial expression detection in computer vision. However, most works focus on camera-based systems installed in the environment. With this method, it is difficult to track user's face(More)
This paper presents a novel smart eyewear that uses embedded photo reflective sensors and machine learning to recognize a wearer's facial expressions in daily life. We leverage the skin deformation when wearers change their facial expressions. With small photo reflective sensors, we measure the proximity between the skin surface on a face and the eyewear(More)
As people use computing devices more and more -not only desktops and laptops but also smart phones and tablets- related health risks also increase. Two of the most common and severe issues related to computer work are (1) the computer vision syndrome (CVS), symptoms include eye fatigue, headaches, dry eyes, blurred vision and (2) a too steep head flexion(More)
We read to acquire knowledge. Reading is a common activity performed in transit and while sitting, for example during commuting to work or at home on the couch. Although reading is associated with high vocabulary skills and even with increased critical thinking, we still know very little about effective reading habits. In this paper, we argue that the first(More)
Head Mounted Display (HMD) provides an immersive ex-perience in virtual environments for various purposes such as for games and communication. However, it is difficult to capture facial expression in a HMD-based virtual environ-ment because the upper half of user's face is covered up by the HMD. In this paper, we propose a facial expression mapping(More)
In this paper, we describe Empathy Glasses, a head worn prototype designed to create an empathic connection between remote collaborators. The main novelty of our system is that it is the first to combine the following technologies together: (1) wearable facial expression capture hardware, (2) eye tracking, (3) a head worn camera, and (4) a see-through head(More)
In this paper, we propose EarTouch, a new sensing technology for ear-based input for controlling applications by slightly pulling the ear and detecting the deformation by an enhanced earphone device. It is envisioned that EarTouch will enable control of applications such as music players, navigation systems, and calendars as an "eyes-free" interface. As for(More)
