In this study, we propose a new Relative position pattern unlocking solution based on blind interaction, which is a new unlocking method, and compared it with existing unlocking methods to verify usability and security improvement. And verified the practical value of the proposed new unlocking solution. The relative position pattern unlock method is easily remembered than the numeric code method and is worth practical enough to show a degree of learning ease similar to the drawing pattern method. The new method is safer to steal than other two methods. It can be manufactured at a low cost and can also be used by special users such as blind people. Therefore, the practical value is relatively high.

Despite abundant research outcomes of blind source separation (BSS) in many types of simulated environments, their performances are still not satisfactory to be applied to the real environments. The major obstacle may seem the finite filter length of the assumed mixing model and the nonlinear sensor noises. This paper presents a two-step speech enhancement method with multiple microphone inputs. The first step performs a frequency-domain BSS algorithm to produce multiple outputs without any prior knowledge of the mixed source signals. The second step further removes the remaining cross-channel interference by a spectral cancellation approach using a probabilistic source absence/presence detection technique. The desired primary source is detected every frame of the signal, and the secondary source is estimated in the power spectral domain using the other BSS output as a reference interfering source. Then the estimated secondary source is subtracted to reduce the cross-channel interference. Our experimental results show good separation enhancement performances on the real recordings of speech and music signals compared to the conventional BSS methods.

A human-friendly interactive system that is based on the harmonious symbiotic coexistence of human and robots is explored. Based on interactive technology paradigm, a robotic cane is proposed for blind or visually impaired travelers to navigate safely and quickly through obstacles and other hazards faced by blind pedestrians. Robotic aids, such as robotic canes, require cooperation between human and robots. Various methods for implementing the appropriate cooperative recognition, planning, and acting, have been investigated. The issues discussed include the interaction between humans and robots, design issues of an interactive robotic cane, and behavior arbitration methodologies for navigation planning.

Purpose: The purpose of this study is to find a way to improve the quality of life of the blind by confirming the effect of the motivation of the blind to participate in golf activities and the effect of income and self-efficacy in these relationships. Research design, data, and methodology: This study conducted a survey of 30 visually impaired people, and simple regression analysis, additive multiple moderating effect analysis were conducted using SPSS and PROCESS macro. Results: First, it was confirmed that the motivation to participate in golf activities is an important factor in improving the quality of life. Second, it was confirmed that income has a positive effect on the quality of life rather than the motivation to participate in golf activities, but self-efficacy negatively affects the quality of life. Third, it was confirmed that the interaction between participation motivation and income level negatively affects the quality of life, but the interaction between participation motivation and self-efficacy improves the quality of life. Conclusions: It suggests that organizations, golf courses, local governments, and volunteers who support the blind's outdoor activities, especially golf activities, need to establish a support system and take a careful approach to overcome these factors.

To explore seismic behavior of blind bolted concrete-filled steel tube (CFST) frames infilled with precast sandwich composite wall panels (SCWPs), a series tests of blind bolted square CFST frames with precast SCWPs under lateral low-cyclic loading were conducted. The influence of the type of wall concrete, wall-to-frame connection and steel brace setting, etc. on the hysteretic curves and failure modes of the type of composite structure was investigated. The seismic behavior of the blind bolted CFST frames with precast SCWPs was evaluated in terms of lateral load-displacement relation curves, strength and stiffness degradation, crack patterns of SCWPs, energy dissipation capacity and ductility. Then, a finite element (FE) analysis modeling using ABAQUS software was developed in considering the nonlinear material properties and complex components interaction. Comparison indicated that the FE analytical results coincided well with the test results. Both the experimental and numerical results indicated that setting the external precast SCWPs could heighten the load carrying capacities and rigidities of the blind bolted CFST frames by using reasonable connectors between frame and SCWPs. These experimental studies and FE analysis would enable improvement in the practical design of the SCWPs in fabricated CFST structure buildings.

By analyzing the film context and taking the film "Blind Mountain", which adapted from a real event in China, as a template, this article aims to analyze the relationship between this type of film and the society from the characteristics of the film adapted from the real event and the relationship with the society after being adapted to films. From the perspective of characteristics, the author also analyzed that firstly, the interactive relationship of presentation is the film's exposure of the real "ugliness" and the perception of "beauty" in the real society. Secondly, the supporting interactive relationship not only enriches the social experience of film creators, but also enhances the film's ability to re-news. Thirdly, the pressure-type interaction is not only to regulate the power of social behavior, but also to promote the intangibility of social thought.

The purpose of this study was to investigate influence of the construction method of the circular skirt on drapability and shape of static silhouette and length variation. In made 24 types of skirts giving the variations (six kinds of peach skin-like finished fabrics two types of cutting method two types of machine stitch method of hem), The results were as follows: 1. Analysis of drapability In the cutting method thre was similarity between warp direction and true bias direc-tion. In the machine stitch method of hem there was similarity between blind stitch and blind stitch machine. According to the fabrics analysis of drapability was excellent in the order N/P 80/20(fabric 1)>P 100(fabric 5)>P 100(fabric 6)>P 100 (fabric 2)>P 100 (fabric 4)>N/C 50/50(fabric 3). 2. Analysis of the characteristics values of static silhouette shape In the cutting method shape of static sil-houette became wide in the warp direction. In the machine stitch method of hem shape of static silhouette became wide in the blind stitch. According to the fabrics shape of static silhouette became most wide in the N/C 50/50(fabric 3) and shape of static sil-houette become most narrow in the P 100(fabric 2,5) 3. Analysis of the length variation In the cutting method the true bias direc-tion was longer than the warp direction. In the machine stitch method of hem there was simi-machine stitch method of hem there was simi-larity between blind stitch and blind stitch ma-chine. In fabrics the P 100(fabric 6) showed the longest the N/C 50/50(fabric 3) showed most slight. Interaction between the cutting and messure-ment part of skirt lengh. In the warp diretion parts that showed longest length variation were C. G, K, O in the true bias diretion parts that showed most slight length variation were A, E, M, I.
