The emergence of the Metaverse is raising important questions in the field of human-machine interaction that must be addressed for a successful implementation of the new paradigm. Therefore, the exploration and integration of both technology and human interaction within this new framework are needed. This paper describes an innovative and technically viable proposal for virtual shopping in the fashion field. Virtual hands directly scanned from the real world have been integrated, after a retopology process, in a virtual environment created for the Metaverse, and have been integrated with digital nails. Human interaction with the Metaverse has been carried out through the acquisition of the real posture of the user's hands using an infrared-based sensor and mapping it in its virtualized version, achieving natural identification. The technique has been successfully tested in an immersive shopping experience with the Meta Quest 2 headset as a pilot project, where a transactions mechanism based on the blockchain technology (non-fungible tokens, NFTs) has allowed for the development of a feasible solution for massive audiences. The consumers' reactions were extremely positive, with a total of 250 in-person participants and 120 remote accesses to the Metaverse. Very interesting technical guidelines are raised in this project, the resolution of which may be useful for future implementations.

This paper describes an interactive multimodal and multisensory fortune-telling experience for digital signage applications that combines digital human agents along with touchless haptic technology and gesture recognition. For the first time, human-to-digital human interaction is mediated through hand gesture input and mid-air haptic feedback, motivating further research into multimodal and multisensory location-based experiences using these and related technologies. We take a phenomenological approach and present our design process, the system architecture, and discuss our gained insights, along with some of the challenges and opportunities we have encountered during this exercise. Finally, we use our singular implementation as a paradigm as a proxy for discussing complex aspects such as privacy, consent, gender neutrality, and the use of digital non-fungible tokens at the phygital border of the metaverse.
Son yıllarda bilgisayar, yazılım ve internet teknolojisinde hızlı bir dönüşüm yaşanmaktadır. Kuşkusuzki bu dönüşüm birçok alanda farklı yansımalara ve yeni kavramların kullanılmasına neden olmaktadır.Nesnelerin interneti, blok zincir, büyük veri, yapay zeka, kripto para, arttırılmış sanal gerçeklik,değiştirilemeyen dijital varlık (NFT-Non Fungible Token), merkezi olmayan finans (Defi), endüstri 4.0gibi kavramlar bunlardan birkaçı olarak ifade edilebilir. Dijitalleşmenin hız kazanmasıyla meslekler debu değişimden etkilenmekte olup, bazı meslekler bütünüyle yok olmakta, bazı meslekler ise değişimve dönüşüm geçirerek yeni meslek alanlarının ortaya çıkmasına sebebiyet vermektedir. Bu durumgelecekte muhasebe bilim alanın ve muhasebe eğitimlerinin dijitalleşme sürecinden etkileneceğinigöstermektedir. Dijitalleşmenin bir sonucu olarak yeni para birimlerinin ortaya çıkması, muhasebepolitikalarının gözden geçirilmesi, muhasebe meslek mensuplarının farklı bilgi ve becerilere sahipolması beklentisi, gelecekte yaşanacak değişimin habercisi olarak kabul edilebilir. Bu çalışmadametaverse kavramı ele alınmış olup, metaverse’nin muhasebe bilim alanına yansımaları incelenmiştir

Although the manufacturing processes of contact lenses are well established, the use of additive manufacturing for their fabrication opens many new possibilities to explore. The current study demonstrates the fabrication of personalized smart contract lenses utilizing additive manufacturing. The study includes 3-dimensional (3D) modeling of contact lenses with the assistance of a computer aided designing tool based on standard commercial contact lens dimension, followed by the selection of the suitable materials and 3D printing of contact lenses. The 3D printing parameters were optimized to achieve the desired lens geometries, and a post processing treatment was performed to achieve a smooth surface finish. The study also presents functionalized contact lenses with built-in sensing abilities by utilizing microchannels at the contact lens edges. Tinted contact lenses were printed and nanopatterns were textured onto the contact lens surfaces through holographic laser ablation. 3D printed contact lenses have advantages over conventional contact lenses, offering customized ophthalmic devices and the capability to integrate with optical sensors for diagnostics.
Adaptive tendril coiling of climbing plants has long inspired the artificial soft microsystem for actuation and morphing. The current bionic research efforts on tendril coiling focus on either the preparation of materials with the coiling geometry or the design of self-shaping materials. However, the realization of two key functional features of the tendril, the spring-like buffering connection and the axial contraction, remains elusive. Herein, we devise a conductive tendril by fusing conductive yarns into tendril configuration, bypassing the prevailing conductivity constraints and mechanical limitations. The conductive tendril not only inherits an electrophysiology buffering mechanics with exceptional conductance retention ability against extreme stretching but also exhibits excellent contractive actuation performance. The integrative design of the ultraelastic conductive tendril shows a combination of compliant mobility, actuation, and sensory capabilities. Such smart biomimetic material holds great prospects in the fields of ultrastretchable electronics, artificial muscles, and wearable bioelectronic therapeutics.
