Humanoid Intelligent Display Platform for Audiovisual Interaction and Sound Identification

This study proposes a rational strategy for the design,fabrication and system integration of the humanoid intelligent display platform(HIDP)to meet the requirements of highly humanized mechanical properties and intelligence for human-machine interfaces.The platform’s sandwich structure comprises a middle lightemitting layer and surface electrodes,which consists of silicon elastomer embedded with phosphor and silk fibroin ionoelastomer,respectively.Both materials are highly stretchable and resilient,endowing the HIDP with skin-like mechanical properties and applicability in various extreme environments and complex mechanical stimulations.Furthermore,by establishing the numerical correlation between the amplitude change of animal sounds and the brightness variation,the HIDP realizes audiovisual interaction and successful identification of animal species with the aid of Internet of Things(IoT)and machine learning techniques.The accuracy of species identification reaches about 100%for 200 rounds of random testing.Additionally,the HIDP can recognize animal species and their corresponding frequencies by analyzing sound characteristics,displaying real-time results with an accuracy of approximately 99%and 93%,respectively.In sum,this study offers a rational route to designing intelligent display devices for audiovisual interaction,which can expedite the application of smart display devices in human-machine interaction,soft robotics,wearable sound-vision system and medical devices for hearing-impaired patients.

Do cardiopulmonary resuscitation real-time audiovisual feedback devices improve patient outcomes? A systematic review and metaanalysis

BACKGROUND Cardiac arrest is a leading cause of mortality in America and has increased in the incidence of cases over the last several years.Cardiopulmonary resuscitation(CPR)increases survival outcomes in cases of cardiac arrest;however,healthcare workers often do not perform CPR within recommended guidelines.Real-time audiovisual feedback(RTAVF)devices improve the quality of CPR performed.This systematic review and meta-analysis aims to compare the effect of RTAVF-assisted CPR with conventional CPR and to evaluate whether the use of these devices improved outcomes in both in-hospital cardiac arrest(IHCA)and out-of-hospital cardiac arrest(OHCA)patients.AIM To identify the effect of RTAVF-assisted CPR on patient outcomes and CPR quality with in-and OHCA.METHODS We searched PubMed,SCOPUS,the Cochrane Library,and EMBASE from inception to July 27,2020,for studies comparing patient outcomes and/or CPR quality metrics between RTAVF-assisted CPR and conventional CPR in cases of IHCA or OHCA.The primary outcomes of interest were return of spontaneous circulation(ROSC)and survival to hospital discharge(SHD),with secondary outcomes of chest compression rate and chest compression depth.The methodo-logical quality of the included studies was assessed using the Newcastle-Ottawa scale and Cochrane Collaboration’s“risk of bias”tool.Data was analyzed using R statistical software 4.2.0.results were statistically significant if P<0.05.RESULTS Thirteen studies(n=17600)were included.Patients were on average 69±17.5 years old,with 7022(39.8%)female patients.Overall pooled ROSC in patients in this study was 37%(95%confidence interval=23%-54%).RTAVF-assisted CPR significantly improved ROSC,both overall[risk ratio(RR)1.17(1.001-1.362);P=0.048]and in cases of IHCA[RR 1.36(1.06-1.80);P=0.002].There was no significant improvement in ROSC for OHCA(RR 1.04;0.91-1.19;P=0.47).No significant effect was seen in SHD[RR 1.04(0.91-1.19);P=0.47]or chest compression rate[standardized mean difference(SMD)-2.1;(-4.6-0.5);P=0.09].A significant improvement was seen in chest compression depth[SMD 1.6;(0.02-3.1);P=0.047].CONCLUSION RTAVF-assisted CPR increases ROSC in cases of IHCA and chest compression depth but has no significant effect on ROSC in cases of OHCA,SHD,or chest compression rate.

Foreign Language Web-Based Learning by Means of Audiovisual Interactive Activities

Online learning has been on an upward trend for many years and is becoming more and more prevalent every day, consistently presenting the less privileged parts of our society with an equal opportunity at education. Unfortunately, though, it seldom takes advantage of the new technologies and capabilities offered by the modern World Wide Web. In this article, we present an interactive online platform that provides users with learning activities for students of English as a foreign language. The platform focuses on using audiovisual multimedia content and a user experience (UX) centered approach to provide learners with an enhanced learning experience that aims at improving their knowledge level while at the same time increasing their engagement and motivation to participate in learning. To achieve this, the platform uses advanced techniques, such as interactive vocabulary and pronunciation assistance, mini-games, embedded media, voice recording, and more. In addition, the platform provides educators with analytics about user engagement and performance. In this study, more than 100 young students participated in a preliminary use of the aforementioned platform and provided feedback concerning their experience. Both the platform’s metrics and the user-provided feedback indicated increased engagement and a preference of the participants for interactive audiovisual multimedia-based learning activities.

Neural Integration of Audiovisual Sensory Inputs in Macaque Amygdala and Adjacent Regions

Integrating multisensory inputs to generate accurate perception and guide behavior is among the most critical functions of the brain.Subcortical regions such as the amygdala are involved in sensory processing including vision and audition,yet their roles in multisensory integration remain unclear.In this study,we systematically investigated the function of neurons in the amygdala and adjacent regions in integrating audiovisual sensory inputs using a semi-chronic multi-electrode array and multiple combinations of audiovisual stimuli.From a sample of 332 neurons,we showed the diverse response patterns to audiovisual stimuli and the neural characteristics of bimodal over unimodal modulation,which could be classified into four types with differentiated regional origins.Using the hierarchical clustering method,neurons were further clustered into five groups and associated with different integrating functions and sub-regions.Finally,regions distinguishing congruent and incongruent bimodal sensory inputs were identified.Overall,visual processing dominates audiovisual integration in the amygdala and adjacent regions.Our findings shed new light on the neural mechanisms of multisensory integration in the primate brain.

Alterations of Audiovisual Integration in Alzheimer’s Disease

Audiovisual integration is a vital information process involved in cognition and is closely correlated with aging and Alzheimer’s disease(AD).In this review,we evaluated the altered audiovisual integrative behavioral symptoms in AD.We further analyzed the relationships between AD pathologies and audiovisual integration alterations bidirectionally and suggested the possible mechanisms of audiovisual integration alterations underlying AD,including the imbalance between energy demand and supply,activity-dependent degeneration,disrupted brain networks,and cognitive resource overloading.Then,based on the clinical characteristics including electrophysiological and imaging data related to audiovisual integration,we emphasized the value of audiovisual integration alterations as potential biomarkers for the early diagnosis and progression of AD.We also highlighted that treatments targeted audiovisual integration contributed to widespread pathological improvements in AD animal models and cognitive improvements in AD patients.Moreover,investigation into audiovisual integration alterations in AD also provided new insights and comprehension about sensory information processes.

Audiovisual Sexual Stimulation and RigiScan Test for the Diagnosis of Erectile Dysfunction

Background： Currently available evaluation criteria lbr penile tumescence and rigidity have been fraught with controversy. In tiffs study, we sought to establish normative Chinese evaluation criteria lbr penile tumescence and rigidity by utilizing audiovisual sexual stimulation and RigiScanTM test （AVSS-Rigiscan test） with the administration of phosphodiesterase-5 inhibitor. Methods： A total of 1169 patients （aged 18-67 years） complained of erectile dysfunction （ED） underwent AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor. A total of 1078 patients whose final etiological diagnosis was accurate by means of history, endocrine, vascular, and neurological diagnosis, International Index of Erectile Function 5 questionnaire, and erection hardness score were included in the research. Logistic regression model and receiver operating characteristic curve analysis were performed to determine the cutoffvalue of the RigiScanTM data. Then, the multivariable logistic analysis was used in the selected variables. Results： A normal restllt is defined as one erection with basal rigidity over 60% sustained for at least 8.75 rain, average event rigidity of tip at least 43.5% and base at least 50.5%, average maximum rigidity of tip at least 62.5% and base at least 67.5%, △tumescence （increase of tumescence or maxinaum-mininaum tumescence） of tip at least 1.75 cm and base at least 1.95 cm, total tumescence time at least 29.75 rain, and times of total tumescence at least once. Most importantly, basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5%, and base at least 50.5% would be the new normative Chinese evaluation criteria for penile tumescence and rigidity. By multivariable logistic regression analysis, six significant RigiScanTM parameters including times of total tumescence, duration of erectile episodes over 60%, average event rigidity of tip, Atumescence of tip, average event rigidity of base, and Atunaescence of base contribute to the risk model of ED. In logistic regression equation, predict value P 〈 0.303 was considered as psychogenic ED. The sensitivity and specificity of the AVSS-RigiScan test with the administration ofphosphodiesterase-5 inhibitor in discriminating psychogenic from organic ED was 87.7% and 93.4%,, respectively. Conclusions： This study suggests that AVSS-RigiScan test with oral phosphodiesterase-5 inhibitors can objectively assess penile tumescence and rigidity and seems to be a better modality in differentiating psychogenic from organic ED. ttowever, due to the limited sample size, bias cannot be totally excluded.

Changes of Effective Connectivity in the Alpha Band Characterize Differential Processing of Audiovisual Information in Cross-Modal Selective Attention

Cross-modal selective attention enhances the processing of sensory inputs that are most relevant to the task at hand.Such differential processing could be mediated by a swift network reconfiguration on the macroscopic level,but this remains a poorly understood process.To tackle this issue,we used a behavioral paradigm to introduce a shift of selective attention between the visual and auditory domains,and recorded scalp electroencephalographic signals from eight healthy participants.The changes in effective connectivity caused by the cross-modal attentional shift were delineated by analyzing spectral Granger Causality(GC),a metric of frequency-specific effective connectivity.Using data-driven methods of pattern-classification and feature-analysis,we found that a change in the a band(12 Hz-15 Hz) of GC is a stable feature across different individuals that can be used to decode the attentional shift.Specifically,auditory attention induces more pronounced information flow in the α band,especially from the parietal-occipital areas to the temporal-parietal areas,compared to the case of visual attention,reflecting a reconfiguration of interaction in the macroscopic brain network accompanying different processing.Our results support the role of α oscillation in organizing the information flow across spatially-separated brain areas and,thereby,mediating cross-modal selective attention.

Suboptimal Auditory Dominance in Audiovisual Integration of Temporal Cues

The present study examined whether audiovisual integration of temporal stimulus features in humans can be predicted by the maximum likelihood estimation （MLE） model which is based on the weighting of unisensory cues by their relative reliabilities. In an audiovisual temporal order judgment paradigm, the reliability of the auditory signal was manipulated by Gaussian volume envelopes, introducing varying degrees of temporal uncertainty. While statistically optimal weighting according to the MLE rule was found in half of the participants, the other half consistently overweighted the auditory signal. The results are discussed in terms of a general auditory bias in time perception, interindividual differences, as well as in terms of the conditions and limits of statistically optimal multisensory integration.

AB054.Audio-visual multiple object tracking

Background:The ability to track objects as they move is critical for successful interaction with objects in the world.The multiple object tracking(MOT)paradigm has demonstrated that,within limits,our visual attention capacity allows us to track multiple moving objects among distracters.Very little is known about dynamic auditory attention and the role of multisensory binding in attentional tracking.Here,we examined whether dynamic sounds congruent with visual targets could facilitate tracking in a 3D-MOT task.Methods:Participants tracked one or multiple target-spheres among identical distractor-spheres during 8 seconds of movement in a virtual cube.In the visual condition,targets were identified with a brief colour change,but were then indistinguishable from the distractors during the movement.In the audio-visual condition,the target-spheres were accompanied by a sound,which moved congruently with the change in the target’s position.Sound amplitude varied with distance from the observer and inter-aural amplitude difference varied with azimuth.Results:Results with one target showed that performance was better in the audiovisual condition,which suggests that congruent sounds can facilitate attentional visual tracking.However,with multiple targets,the sounds did not facilitate tracking.Conclusions:This suggests that audiovisual binding may not be possible when attention is divided between multiple targets.

Audiovisual Multimedia Combined with Standard, Verbal, Informed Consent;Enhancing the Satisfaction and Comprehension of Surgical Patients: A Comparative Trial in Patients Undergoing Laparoscopic Cholecystectomies at the HRH Princess Maha Chakri Sirindhorn Medical Center, Thailand

Objective: A comparative study of the audiovisual, multimedia, informed consent procedure enhancing the satisfaction and comprehension in laparoscopic cholecystectomy patients within the contexts of the Thai culture. Methods: A prospective, comparative trial was done in patients undergoing laparoscopic cholecystectomies at the HRH Princess Maha Chakri Sirindhorn Medical Center in Thailand. Before the procedure, all patients who met the selection criteria and agreed to participate in the study by signing the proper consent forms were placed into 2 groups. G1 (group 1) was informed with the standard verbal informed consent and G2 (group 2) was informed with audiovisual multimedia in the form of a DVD in collaboration with the standard, verbal, informed consent procedure. The patients were interviewed by a nurse, using a checklist type of questionnaire, as to their satisfaction and comprehension of the procedure on the day of discharge. Results: In the period of June 2010 through December 2010, 60 patients undergoing laparoscopic cholecystectomies and who had met the conditions of research were included in our study. There were 30 patients in each group. The average satisfaction score in G1 was 3.12 out of a total of 5 and in G2 was 4.51 of 5 (P < 0.001). The percentage of patients that had an understanding of the operative information: 1) Understood ≥ 50% of information;G1 was at 13.33% and G2 was at 70.00%;2) comprehension of 1% - 49% of the information;G1 was at 20.00% and G2 was at 26.67%;3) No comprehension;G1 was measured at 66.67% and G2 was at 3.33%. The subgroup included the analysis of 7 items of information (operative indications, operative process, operative results, possible complications, wound care, diet, conditions for returning to work) and these were understood at a higher level in G2 than those in G1 (P < 0.001). Conclusions: In the context of the Thai culture;high technology, audiovisual multimedia combined with the standard, verbal, informed consent process enhanced the satisfaction and the comprehension of patients undergoing a laparoscopic cholecystectomy. Audiovisual multimedia should have the appropriate content, be clear, comprehensive and should include images and the voice of the surgeon who will be performing the operation to help the patient feel confident in the surgeon and in their decision to proceed with the surgery. Providing information in DVD form will benefit patients as they can examine it by themselves in the comfort of their home before the surgery and review the material as many times as may be required to provide a full understanding.

声影洞见——音乐影像志在当代

美国民族音乐学家Mantle Hood在1971年曾指出“对于民族音乐学者而言,影像构成了一种独特的或最重要的可用文献”。经过一个多世纪的发展,影音民族音乐学(Audiovisual Ethnomusicology)从开始关注异国情调的采集或附着于人类学及民族志学者的田野影像,逐渐发展为一个以学科交叉为特征的新型学术方向,影像也从民族音乐学研究的辅助手段逐步形成具有独立表达与风格的音乐影像志。近年来随着科技发展、影像设备普及和新媒体时代的到来,音乐影像志面临着新的发展契机。2019年上海音乐学院首开音乐影像志学硕士学位点,同年首创“华语音乐影像志展映”活动,随后再以“双年展”方式推动该方向在学科意义上的发展。作为亲历者,本文将简短回顾该方向的学术积累,并以两届“华语音乐影像志”参展作品为例证,讨论多样性音乐影像志的当代意义与面对的问题。

Alteration of the temporal association between courtship audio and visual components affects female sexual response

Some multimodal signals-that is,occurring in more than one sensory modality-appear to carry additional information which is not present when component signals are presented separately.To understand the function of male ring dove’s(Streptopelia risoria)multimodal courtship,we used audiovisual playback of male displays to investigate female response to stimuli differing in their audiovisual timing.From natural courtship recordings,we created a shifted stimulus where audio was shifted relative to video by afixed value and a jittered stimulus,where each call was moved randomly along the visual channel.We presented 3 groups of females with the same stimulus type,that is,control,shifted,and jittered,for 7 days.We recorded their behavior and assessed pre-and post-test blood estradiol concentration.We found that playback exposure increased estradiol levels,confirming that this technique can be efficiently used to study doves’sexual communication.Additionally,chasing behavior(indicating sexual stimulation)increased over experimental days only in the control condition,suggesting a role of multimodal timing on female response.This stresses the importance of signal configuration in multimodal communication,as additional information is likely to be contained in the temporal association between modalities.

Decoding Ang Lee's Crouching Tiger,Hidden Dragon:A Sociosemiotic Approach

This study takes a sociosemiotic approach to decode Ang Lee’s Crouching Tiger, Hidden Dragon that is seen as an audiovisual discourse and also a symbolic representation. An analytical model that incorporates linguistic, semiotic and cultural analysis is constructed.The findings reveal that Crouching Tiger, Hidden Dragon internalizes a hybrid intercultural Chinese identity that has rooted in Ang Lee’s cognition of an imagined cultural China.Symbolically, a profound Chinese wuxia story that contains interwoven conflicts and negotiations between Chinese traditional culture and Western humanistic values is presented. The English translation of subtitles plays a key role in bridging the gap between Chinese culture and Western audiences, facilitating the dialogue between East and West.Significantly, Ang Lee’s adaptation of plots, shaping of figures, symbolic representation of China’s landscapes and also the use of language to some extent are for catering to Western audiences. Although the romantic imagination of “Cultural China” presents a multicultural cooperation of Chinese and Western culture, it objectively reinforces the ideological symbol of China as an orientally cultural “other” to the Western world.
