Tai-Chi Chuan (TCC) is a famous physical exercise and well-known for being able to effectively promote physical well-being. Many people have been interested in learning TCC at the beginning, but eventually failed in mastering it due to the lack of a constantly accompanying master on the side. In this paper, we present an augmented-learning tool, called "My(More)
Most people choose shoes mainly based on their foot sizes. However, a foot size only reflects the foot length which does not consider the foot width. Therefore, some people use both width and length of their feet to select shoes, but those two parameters cannot fully characterize the 3-D shape of a foot and are certainly not enough for selecting a pair of(More)
With the recent advances of head-mounted displays (HMD) for immersive virtual reality, game designers are able to provide players with many different gameplay to manipulate in the virtual environment. Like most of the console platforms and portable devices, tactile feedback is an important aspect in games and for notification. For example, Po2 [Israr et al.(More)
We present SoEs (Sword of Elements), an attachable augmented haptic device for enhancing gaming controller in the immersive first-person game. Generally, Player can easily receive visual and auditory feedback through head-mounted displays (HMD) and headphones from first-person perspective in virtual world. However, the tactile feedback is less than those(More)
Current CSMA-based MAC protocols for wireless sensor networks (WSNs) do not support prioritized channel access and often suffer from varying degrees of starvation and fairness problems. That is, with a little bad luck, a sensor node might have to wait arbitrarily long to send its frame, and thus results in the invisibility of some sensed area. In this paper(More)
Gaming controller is a general way for playing in the immersive virtual reality (VR) game. With haptics technology and head-mounted display (HMD), user can have an enhanced immersive experience when they manipulate in the virtual environment. Currently, the VR controller only provide vibration feedback when player interact with the virtual object. For(More)
Slow Start Backoff (SSB) Algorithm is a simple, efficient, distributed, and well performing medium access control (MAC) layer protocol designed for ad-hoc wireless networks to share the medium. SSB is able to alleviate intensive collisions in high load environments, and SSB can also minimize the average channel access delay in light load environments.(More)
To alleviate cybersickness in the immersive virtual reality (VR), teleportation is a common method of moving around in virtual spaces. Although users can receive the visual and auditory feedbacks from their first-person perspective with the advances of immersive head-mounted displays (HMD), they do not have the haptic experience when they teleport to(More)
Recently, Virtual Reality (VR) has shown the ability of providing immersive experience to users and taking them to travel around the virtual environment. Sometimes when traveling in a large-scale virtual environment, the tracking space may not be large enough to fit the virtual environment. Several moving approaches such as virtual jumping and flying are(More)
