Real-Time Table Tennis Scoring and Player Position Tracking System Using Computer Vision

This study focuses on developing a system that uses state-of-the-art computer vision techniques to improve the accuracy and efficiency of table tennis tracking. The table tennis ball's trajectory and movement are tracked automatically by the system using a mobile camera array, allowing for real-time score updates without the need for human participation. This method guarantees precise and seamless scoring, freeing players from worrying about maintaining score and allowing them to concentrate fully on the game. The system uses player pose estimation technologies in addition to real-time scoring to track and record player positions and motions during the match. The system may provide a thorough study of player motions, including tracking posture and finding important motion patterns, by gathering and analyzing skeletal data.

Do players with superior physiological attributes outwork their less-conditioned counterparts? A study in Gaelic football.

This study investigated the association of physiological attributes with in-game workload measures during competitive Gaelic football match-play. Fifty-two male developmental level Gaelic football players (mean ± SD; age: 22.9 ± 3.8 years) underwent measurements of anthropometric characteristics, running speed, muscular strength and power, blood lactate (BLa), running economy and aerobic capacity during two separate testing visits. Global Positioning System units (18-Hz) were used to record players in-game workloads during a competitive match 1-week following the baseline physiological assessments. Results indicated that players body fat percentage, drop jump height (DJ) and running velocity at 4 mmol · L-1 BLa were significantly associated with the number of high-speed runs completed (Adjusted R2 26.8% to 39.5%; p < 0.05) while 20 m running speed, running velocity at 2 mmol · L-1 BLa and DJ were significantly associated with the number of accelerations completed (Adjusted R2 17.2% to 22.0%; p < 0.05) during match-play. Additionally, aerobic capacity and body fat percentage were significantly associated with total distance (Adjusted R2 14.4% to 22.4%; p < 0.05) while body fat percentage, DJ and 20 m running speed were significantly associated with high-speed distance (Adjusted R2 17.8% to 22.0%; p < 0.05). Players were also divided into higher-standard and lower-standard groups using a median split of these physiological attributes. Players in the higher-standard groups completed significantly more high-speed runs and accelerations and covered significantly larger total and high-speed distances (+10.4% to +36.8%; ES = 0.67 to 0.88; p < 0.05) when compared to the lower-standard groups. This study demonstrates that superior levels of physical conditioning are associated with larger in-game workloads during Gaelic football match-play.

Checking Different Video Game Mechanics to Assess Cognitive Abilities in Groups with and without Emotional Problems.

This study assesses cognitive abilities through video games for entertainment (Blek, Edge, and Unpossible) that were programmed from scratch to record players' behavior and the levels achieved in a sample without emotional problems and in one with emotional problems. The non-emotional-problem sample was recruited from three universities and two bachelor's degree programs. The emotional-problem sample was recruited from two outpatient centers. The participants in the emotional-problem sample completed reduced versions of the ability tests and video games, as required by their emotional problems. Three subtests of the Differential Aptitude Test that assessed abstract reasoning, visuospatial reasoning, and perceptual speed were selected as ability tests. All participants were required to complete a mental health questionnaire (PROMIS) and a brief questionnaire on their gaming habits and previous experience with the video games used. The results that were obtained showed good convergent validity of the video games as measures of cognitive abilities, and they showed that the behavior of players in the sample without emotional problems while playing predicted the level achieved in the Blek and Unpossible game fragments, but this was only true for Unpossible in the emotional-problem sample; finally, shorter versions of the Blek and Edge game fragments can be used because they maintain their good psychometric properties.

The wreck of the Gloucester revisited

Abstract The wreck of the frigate Gloucester off Norfolk on 6 May 1682 has always figured in histories of the Restoration period; it was taking James, Duke of York (the future James II and VII) to Edinburgh to collect his wife Mary of Modena and his daughter Princess Anne after his years of exile in Scotland. It has long been known that there were royal musicians on board, two of whom were drowned, though interest in the subject has been rekindled by the discovery of the wreck and an exhibition of artefacts from it in Norwich in 2023. Some other historic wrecks have proved to contain musical instruments, including the Mary Rose and several Dutch ships, though the Gloucester is unique in that a musical artefact—a brass trumpet mouthpiece—can be matched to documentary evidence concerning the musicians on board. Court documents concerned with replacing lost instruments and compensating survivors and the families of victims show that those on board included four royal trumpeters and a kettledrummer (Walter Vanbright, who was drowned); a five-man group drawn from the Twenty-Four Violins, led by the composer Thomas Farmer and including Thomas Greeting (who was also drowned); and the oboist, recorder player and bass violinist James Paisible, who had apparently been working in Edinburgh in the Duke of York’s household. Paisible may have been a member of Farmer’s string group, though there is a possibility that he was accompanied by three other French musicians, forming a separate recorder/oboe consort. An anecdote concerning James rescuing the string player Edmund Flower from drowning throws light on the musical and religious politics on board the Gloucester: the earliest version, published in 1730, claimed wrongly that the duke ‘turn’d him out of his band because he would not turn Papist’.

Marketing objects as talking machines: The performative capacity of product packages

In this paper, I extend the established concept of performativity by focusing on the origins and micro-level interactional strategies of marketing objects. In product markets wherein face-to-face interactions between buyers and sellers are impossible, profit-seeking firms depend upon marketing objects—and on their packaging stories—to interact with buyers. While much research focuses on the particular effects of performative marketing objects on consumers, I explore the conditions required for such effects to emerge. In this project, I employ a richly descriptive case study design by focusing on a transnational specialty food firm based in Indonesia and examining the complete collection of food product packages ( N = 81) that communicate with buyers on behalf of its products for sale. I understand marketing practices as helping to create the phenomena they allegedly describe, and thus contribute to object-oriented marketing theory through a dramaturgical analysis of packaging talk.

From Talking Machines to Music Machines: The Early Years of Recorded Sound and Playback in Pictures and Audio

AbstractBetween Thomas Edison’s invention of the phonograph in 1877 and World War I, inventors, entrepreneurs, performers, and listeners transformed the singular talking machines of the late 1870s to the ubiquitous music machines of the twentieth century. Through selected images, objects, and links to period sounds, this essay offers a chronological glimpse of interacting social, technical, and entrepreneurial forces at work. Combining visual, aural, and material sources in this way enlarges the historian’s toolbox for understanding the late nineteenth and early twentieth centuries.

52 ‘I remember when. . .’—environmental, event-based and personally relevant objects that support reminiscence in virtual reality and other digital settings

Abstract Background Limited but growing evidence is emerging to support technology-supported reminiscence. Although some studies involved older adults, few included people with dementia. Little guidance is available for facilitators regarding the themes and objects that best support reminiscence in a digital environment or those that are best used with a cognitively impaired population. This study aimed to address this research gap. Methods Thirty-seven older adults, with and without cognitive impairment, collaborated with our research team across two rounds of participatory workshops; held in each of two locations (urban and rural town). The first involved capturing and probing memories from young childhood to present day. Workshop discussion and outputs were thematically analysed, themes with higher levels of engagement were identified and content analysis of each theme identified associated objects. These results were reviewed in the second workshop and recommendations were made as to how they could best be used in digital environments. Results Engaged and positive reminiscence experiences were supported by: Environmental Objects—prompting memories closely linked with specific settings (e.g. school, childhood home, playing on the street, old shops); Event Objects—triggering memories relating to specific occasions of types of events (e.g. holidays, dances, sports, hobbies); and Meaningful Objects—items with personal relevance for individuals (e.g. first bike, record player, telegram). Object-rich digital environments were deemed to best support VR reminiscence, rather than single item interactions which can be effective for in-person sessions. Conclusion Objects recommended for use in digital VR reminiscence support the limited findings that are available from previous research. Fewer cross cultural differences were noted, and we recommend that this research is extended to learn more about reminiscence prompts in more ethnically diverse groups. Nevertheless, a catalogue of objects, environments and meaningful events are now available to support clinical and technical developers of digital reminiscence.

Deep Learning Based Player Identification Via Behavioral Characteristics

Behavioral recognition in game is a fundamental topic in data analysis. With the emerging of deep learning-based method, more and more artificial neural networks are proposed to achieve higher accuracy and robustness. This paper presents a comparison between CNN and RNN-LSTM for player identification based on player behavioral characteristics in a simple game environment. The goal is to detect potential manual cheating in competitions by recognizing unidentified players (cheaters) from their behavioral patterns. We implement a basic game, record player behaviors, and then compare the accuracy of outputs from the CNN and RNN-LSTM models. The conclusion is summarized as follow. CNN obtains 87.5% accuracy and RNN-LSTM achieves 92.3% accuracy in the simulated data. Our results indicate that the RNN-LSTM model outperforms the CNN model in terms of accuracy, making it a more suitable choice for player identification in this contextt.

Fonógrafos ambulantes en tiempos de don Porfirio: Hacia una historia popular de los sonidos (Ciudad de México, 1894–1903)

At the end of the nineteenth century, talking machines stopped being inaccessible to the popular sectors and became objects of daily Mexican life. It was in this context that dozens of individuals, aware of the popular predilection for recorded music and interaction with sound technologies, decided to request authorization from the city council of Mexico City to rent out their phonographs on public roads. They would receive a penny for each phonogram listened to by their clients. The need of these popular entrepreneurs for an attractive and varied repertoire prompted the emergence of shops and small recording studios in the city. This article attempts to reconstruct this forgotten chapter in the business and cultural history of Mexico. To do this, we will not only reveal the identities of the phonographers, the objects they rented, and the places they traveled but also the accusations they faced for the spread of hearing diseases and the reproduction of obscene songs. In general, this research highlights the methodological relevance of an approach that rethinks the past, having as its central axis the study of the processes of commercialization and consumption of sounds in the daily life of cities.

Records Reformed and Reused. Nostalgic and Ecological Concerns in Contemporary Media Art

In the twentieth century, records and record players were employed as the media and medium of art and music. These generative practices sought to extend the possibilities for sound production, at times ending in the destruction of both vinyl and turntable—what I call cracked media. This paper will revisit cracked media in the twenty-first century, inquiring into how this (re)interest in vinyl has translated into art and music. I will look to contemporary musicians and artists to contrast practices that encapsulate nostalgia with those that seek to communicate ecological and environmental concerns.

“¿Cuánto por una máquina parlante?”: estrategias cotidianas para acceder al mágico mundo de los sonidos grabados (México, 1903-1910)

Objective/Context: This article aims to demonstrate how, despite the high prices of talking machines for the pockets of the Mexican working classes, these sectors used various practices and mechanisms to enter the world of recorded sounds. This story develops in a specific context of the social uses of talking machines in Mexico, marked by the interest of several American companies in the country’s sound market, such as Victor Talking Machine Company, National Phonograph and Columbia Record, whose directors sent technicians to record hundreds of records and cylinders with pieces performed by cultured and popular artists. Methodology: The tools of cultural history and a wide range of periodical sources, and, to a lesser extent, governmental petitions, are used to capture segments of the workings of the everyday economy and the consumption strategies of talking machines. Originality: This is a topic scarcely addressed by phonographic studies in Mexico, which have concentrated on analyzing musical recordings rather than understanding the consumption of these products. By considering income, consumers’ spending capacity and the commercial strategies of businesses, this text reveals different applications of talking machines at the educational, domestic and occupational levels to explain how they were transformed into desired commodities. Conclusions: After highlighting the cost of living at the time and the wages of workers, artisans and peasants, the research concludes that practices such as raffles, theft, the offer of itinerant phonographers, listening in commercial establishments and installment purchases, among others, allowed the less privileged to have access to the apparently unattainable devices imported between 1903 and 1910.

Effects of saccadic and scent stimulations on driver attentiveness in automated driving systems

Level 3 automated driving requires a driver to operate a vehicle in response to a takeover request according to the Society of Automotive Engineers; therefore, the driver should maintain a state of wakefulness. The study aimed to evaluate and verify whether the presented stimuli, i.e., saccade-inducing stimuli (SaS) as visual stimuli, scent stimuli (ScS) as olfactory stimuli, and a combination of saccade-inducing and scent stimuli (CoS), can maintain the wakeful state of a driver. A driving simulator (DS) that can reproduce the actual movement of a motor vehicle using a turn table and six-axis motion device is used to simulate driving under four different conditions: no stimulation, SaS, ScS, and CoS. The percentage of eye closure (PERCLOS) and the electroencephalogram (EEG) analysis were used for the quantitative evaluation, while the participants were subjected to subjective evaluation. The results showed that the average increase in arousal time for each condition was 30.2, 53.7, and 82.3% for the SaS, ScS, and CoS cases, respectively. The average reduction rate in the EEG readings was 39.9, 41.0, and 71.4% for the SaS, ScS, and CoS cases, respectively. All participants indicated that the CoS had the highest effect of arousal as a driver stimulation tool.

Problemo de tempo en verkoj de Jacob van Eyck bazitaj sur melodioj de profanaj kantoj. Studo de ekzemploj (ESPERANTO)

Der Fluyten Lust-hof by Jacob van Eyck (circa 1590-1657) is the largest collection of works for a solo instrument in the history of European music, which documents both the variety of techniques of early Baroque ornamentation and presents the vast repertoire of popular and folk songs of that time. It was that type of compositions that the blind recorder player also known as the Orpheus of Utrecht used to choose as the basis for his famous, improvised instrumental arrangements, which were later dictated by him in order to be published. After van Eyck’s death, his compositions lost popularity and were soon forgotten, and the new wave of interest in the works included in Der Fluyten Lust-hof only emerged in the 1970s along with the development of the historical performance trend. At present, van Eyck’s musical activity is relatively well explored, which we primarily owe to the work of Ruth van Baak Griffioen and Thiemo Wind. Despite that, some problems remain unsolved. One of the particularly important issues is related to the nature of separate compositions and the pacing in which they could be rendered at that time, which is still a subject of disputes among both musicologists and recorder players. Using three compositions as an example, this article presents a method to reconstruct this aspect of musical practice coming from the analysis of notation patterns and the comparison of the van Eyck’s ornamentation style with earlier written down compositions on the basis of which he created his improvisations. This last standpoint made it possible to show that the diminutions created by van Eyck in many cases do not have a purely technical character, and in some of them one can find numerous musical phrases indicative of a deeper connection between the variations included in Der Fluyten Lust-hof and lyrics of original songs and the specificity of their melodies than previously thought.

How Audio is Getting its Groove Back: Deep learning is delivering the century-old promise of truly realistic sound reproduction

NOW THAT RECORDED SOUND has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it's an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week. • Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison's phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
