In this paper, we present a double hand-gesture interaction (DHGI) method for walk-through in VR environment with an Oculus Rift headset and Leap Motion function. The user can control the avatar (first-person view) to move (walk/run) forward or backward by turning user's left palm upward downward, right thumb pointing toward either direction. Compared results of joystick input device portal using Touches, objective subjective findings study indicate that DHGI is intuitive, easy learn, use,...
The reason for wider color gamut of laser display systems rests on RGB lights whose coordinates very approach the locus chart, which means most saturated colors. A novel, practical and simplest method to reduce speckle is developed. digital cinema projector (LDCP) manufactured first time in world. LDCP enjoys all benefits 166% NTSC expanded gamut, beyond 9 024 ANSI lumens light output, a minimum sequential contrast ratio 2595:1, 2048 X 1080 resolution, etc.
Tactile displays1 have been widely used in information transfer through various tactile patterns on mobile devices. The fundamental consideration designing interactions is intuitive feedback that convey information. This study investigates the user perception of stimuli over frictional surface phones terms strong feedback. We designed 36 different with a combination signal lengths (w1 = 0.2-3.2 mm) and intervals (w2 feedbacks. These parameters covered most cases pattern design for phone....
The quasiphase matched PPMgLN crystal is used intracavity frequency doubled to obtain high power green laser, with a pump of 20 W at 808 nm, 6.67 output 532 nm achieved.
Taking self-portraits with a digital camera is popular way to present oneself through photography. Traditional techniques for taking self-portraits, such as use of self-timers or face detection, provide only modest degree interaction between the user and camera. In this paper, we an technique that make novel image-processing algorithm recognize hand motion gestures provides natural interact self-portraits. User can perform nature control essential functions take effectively. Three types...
In this paper, the convolutional recurrent neural network (ConvLSTM) architecture is proposed to predict individual stock prices. The characteristics of data are automatically extracted through (CNN). Afterward, features inputted into a long short-term memory (LSTM) model with for prediction. Since CNN has been representation learning model, it quite appropriate automatic feature extraction. Besides, LSTM could effectively surmount issues gradient disappearance and expansion time series...
Urban water bodies play a critical role in regulating urban climate, mitigating the heat island effect, and enhancing ecological environments. This study focuses on five typical cities Zhejiang Province, systematically analyzing cooling effects of bodies. Specifically, divides buffer zones into basic analytical units based road network performs land surface temperature inversion use classification using Google Earth Engine platform. Six representative morphology indicators are selected,...
908 mW of green light at 532 nm were generated by intracavity quasiphase matching in a bulk periodically poled MgO:LiNbO 3 (PPMgLN) crystal. A maximum optical‐to‐optical conversion efficiency 33.5% was obtained from 0.5 mm thick, 10 long, and 5 mol% crystal with an end‐pump power 2.7 W 808 nm. The temperature bandwidth between the single‐pass frequency doubling found to be different for PPMgLN. Reliability stability laser evaluated. It that continuous operation 100 hours, output better than...

Besides overview statistical view it also...
Most existing digital camera user interfaces place little emphasis on self- portrait options. Therefore, it is not always easy to take self-portraits using conventional interfaces. This paper presents a vision-based head gesture interface for controlling self-portrait that helps users effectively and efficiently. Intu- itive nodding head-shaking gestures control the zoom in/out face, mouth-opening triggers picture. We evaluated its usability factors (effectiveness, efficiency, satisfaction)...
Digital cameras are widely used in desktop and notebook PCs. Taking self-portraits is one of the important function such cameras, which allows users to capture memories, create art, improve photography techniques. A environment with a large display pan-and-tilt camera provides good area for exploring more angles postures while taking self-portraits. However, most existing interfaces this type limited device-based systems (i.e., mouse keyboard) that prevent from efficiently controlling This...
In this paper, we propose two active tactile texture interaction methods enabling eye-free number (0-9) reading on a variable-friction surface for smartphone equipped with TPad device. We employ four discriminative stripe-based textures to represent different numbers, namely, 0, 1, 2, and 5, combine them the other numbers. For first method, adopt simple left/right slider motion gestures (LRSM), second, utilize up down (UToDSM). examined interactive efficiency, recognition accuracy,...
