Event-based tracking of human hands

Purpose This paper proposes a novel method for human hands tracking using data from an event camera. The event camera detects changes in brightness, measuring motion, with low latency, no motion blur, low power consumption and high dynamic range. Captured frames are analysed using lightweight algorithms reporting three-dimensional (3D) hand position data. The chosen pick-and-place scenario serves as an example input for collaborative human–robot interactions and in obstacle avoidance for human–robot safety applications. Design/methodology/approach Events data are pre-processed into intensity frames. The regions of interest (ROI) are defined through object edge event activity, reducing noise. ROI features are extracted for use in-depth perception. Findings Event-based tracking of human hand demonstrated feasible, in real time and at a low computational cost. The proposed ROI-finding method reduces noise from intensity images, achieving up to 89% of data reduction in relation to the original, while preserving the features. The depth estimation error in relation to ground truth (measured with wearables), measured using dynamic time warping and using a single event camera, is from 15 to 30 millimetres, depending on the plane it is measured. Originality/value Tracking of human hands in 3 D space using a single event camera data and lightweight algorithms to define ROI features (hands tracking in space).

Cast iron artifact

Путешественник нечасто смотрит под ноги. А зря. Совсем небольшие и огромные канализационные люки и решетки интересны как творения рук человеческих и свидетели бурной жизни, что проносится над ними. Ключевые слова: канализационный люк, водопровод, промышленное наследие, городская культура, коммунальное хозяйство, урбанистика, коллекция, ливневая решетка, городской ландшафт, коммуникации, чугун, торевтика, музей. A traveler does not often look under his or her feet. However, in vain. Even small and more over huge sewer manholes and grates are interesting as the creations of human hands and witnesses of turbulent life that passes over them.

Origami Folding by Multifingered Hands with Motion Primitives

Origami, a traditional Japanese art, is an example of superior handwork produced by human hands. Achieving such extreme dexterity is one of the goals of robotic technology. In the work described in this paper, we developed a new general-purpose robot system with sufficient capabilities for performing Origami. We decomposed the complex folding motions into simple primitives and generated the overall motion as a combination of these primitives. Also, to measure the paper deformation in real-time, we built an estimator using a physical simulator and a depth camera. As a result, our experimental system achieved consecutive valley folds and a squash fold.

Kontribusi konsep Green Moral Dalam Mendukung SDGs di Era Revolusi Industri 4.0

ABSTRAKPenelitian ini dilatar belakangi oleh berbagai permasalahan lingkungan yang terjadi saat ini. Kerusakan lingkungan yang dihadapi sedikitnya terjadi dari ulah tangan manusia yang tidak bertanggung jawab. Tujuan penelitian ini untuk memberikan pandangan masyarakat tentang pentingnya menjaga dan melestarikan alam, agar alam itu memberikan kebermanfaatan untuk kehidupan. Pendekatan yang digunakan adalah kualitatif dengan metode etnopedagogi. Hasil penelitian yang penulis peroleh yaitu: (1) Proses pembinaan masyarakat melalui adat istiadat yang sudah lama terbangun memberikan filosofis kuat dalam bersikap bijak terhadap alam,melalui adat istiadat upacara adat nyuguh, babarit, dan sedekah bumi. (2) Dalam mempertahankan adat istiadat di tengah Revolusi Industri 4.0, dengan membumikan nilai-nilai adat yang bermilai luhung terutama dalam menyeleksi dan membatasi teknologi-teknologi yang dirasa kurang bermanfaat untuk masyarakat sekitar. (3) Konsep SDGs, sangat didukung oleh masyarakat adat Kuta terutama dalam pelestarian alam. Masyarakat masih memegang teguh pelestarian alam dengan sangat menghormati lingkungan alamnya, alam itu dijadikan sebagai nilai kehidupan tertinggi bagi mereka. ABSTRACTThe contribution of the green moral concept in supporting the SDG's in the era of the Industrial Revolution 4.0. This research is motivated by various environmental problems that occur today. The environmental damage faced is at least caused by irresponsible human hands. The purpose of this research is to provide a view of the community about the importance of protecting and preserving nature, so that nature can provide benefits for life. The approach used is qualitative with the ethnopedagogical method. The results of the research that the authors obtained are: (1) The process of community development through long-established customs provides a strong philosophical attitude towards being wise towards nature, through the customs of the ceremonies of nyuguh, babarit, and earth alms. (2) In maintaining customs in the midst of the 4.0 Industrial Revolution, by grounding customary values that have noble values, especially in selecting and limiting technologies that are deemed less beneficial to the surrounding community. (3) The concept of SDGs is strongly supported by the Kuta indigenous people, especially in nature conservation. People still uphold the preservation of nature with great respect for their natural environment, this nature is used as the highest value of life for them.

TGH Sibawaihi Mutawalli : Kajian Lingkungan dalam Dakwah Modern Islam di Lombok

There has been destruction on this earth both on land and in the ocean as a result of the act of human hands (Al- Qur'an, Ar-Rum; 41). Floods, landslides, forest and land fire which are the result of illegal logging, land burning, forest encroachment are clear evidence of fragments of the above verses of the Qur'an. Though man sent by God Almighty Allah as a leader of the earth who should take care and sustain the environment, and Muslims in particular are assigned as a mercy of the universe (rahmatan lil alamin). Seeing this situation, it needs a Muslim who can be a transformer, driver, accelerator, trigger, and protector to guide human in maintaining and utilizing the environment wisely. On the island of Lombok, socio-culturally in which the figure of Tuan Guru as is the informal leader that considered will be capable of carrying this heavy task. Tuan Guru Haji (TGH) Sibawaihi is a figure who considered has the ability of being the Muslim Scholar (Ulama) who plays an important role in environmental conservation, especially in Lombok Island. This is because he has a complete Tuan Guru type which considered as the requirements of being Environment based da’wah, he has the type of Tuan Guru intellectual, Tuan Guru Pesantren, Tuan Guru Guru Panggung and Tuan Guru Tarekat. Besides, he is also well known as a Tuan Guru who full of motivation and strong on act, innovation and smart on concept, inspire and transform the social-culture life. Lastly his philosophy on concept and act is based on Qur’an, Hadits and the full of fear of almighty Allah SWT.

Companion or Substitution? Automation and Digitisation in the Workplace

The production process is no longer purely limited to human workers. Automation and digitisation have come in. Workers are aided by various machines that assist them in production. This has led to faster production and lower prices. The benefits are obvious, yet up to what extent can we automate and digitise production? Will it ever come to a point when we would no longer need any human intervention to produce the things we need? Can the digital and the automated ever substitute human hands? This article offers a brief discussion on how digitisation and automation have affected our lives and the way we work. It presented an overview of automation’s history and recent developments. Moreover, it discussed the various opportunities and risks associated with these fast improvements. Lastly, an analysis of the possible future of digitisation was mentioned: What must be done to take full advantage of the opportunities and to curb the risks? Automation has made production faster and this has led to various benefits and opportunities just waiting to be taken advantaged off, yet I firmly believe that human labour will continue to flourish. Automation and digitisation may have been going on for decades, but human work still exists because there are aspects of work that cannot just simply be replaced by machines. Machines are to complement us and help us to do things better. Moreover, there should be a focus on education and on fostering a culture of innovation so that we can be ready to face any changes in the workplace. There should also be a conscious effort to fight the factors that further inequality in society.
