Main Barrier

Current hand wearables have limited customizability, they are loose-fit to an individual's hand and lack comfort. The main barrier in customizing hand wearables is the geometric complexity and size variation in hands. Moreover, there are different functions that the users can be looking for; some may only want to detect hand's motion or orientation; others may be interested in tracking their vital signs. Current wearables usually fit multiple functions and are designed for a universal user with none or limited customization. There are no specialized tools that facilitate the creation of customized hand wearables for varying hand sizes and provide different functionalities. We envision an emerging generation of customizable hand wearables that supports hand differences and promotes hand exploration with additional functionality. We introduce FabHandWear, a novel system that allows end-to-end design and fabrication of customized functional self-contained hand wearables. FabHandWear is designed to work with off-the-shelf electronics, with the ability to connect them automatically and generate a printable pattern for fabrication. We validate our system by using illustrative applications, a durability test, and an empirical user evaluation. Overall, FabHandWear offers the freedom to create customized, functional, and manufacturable hand wearables.

The Creation

In the framework of Virtual CMM [1], virtual parts are proposed to be constructed as triangulated surface models. This paper presents a novel surface reconstruction method to the creation of virtual parts. It is based on the idea of identification and sculpting of concave regions of a Delaunay triangulation of the sample data. The proposed algorithm is capable of handling the reconstruction of surfaces with or without boundaries from unorganized points. Comparisons with other Delaunay-based algorithms show that it is more efficient in that it can optimally adapt to the geometric complexity of the sampled object. To validate the proposed algorithm, some detailed illustrations are given.

Change State

Transforming products, or more generally transformers, are devices that change state in order to facilitate new, or enhance an existing, functionality. Mechanical transformers relate to products that reconfigure and can be advantageous by providing multiple functions, while often conserving space. A basic example is a foldable chair that can be stowed when not in use, but provides ergonomic and structural seating when deployed. Utilizing transformation can also lead to novel designs that combine functions across domains, such as an amphibious vehicle that provides both terrestrial and aquatic transportation. In order to harness these assets of transformation, the Transformational Design Theory [1] was developed. This theory outlines a set of principles and facilitators that describe and embody transformation for the purpose of systematically assisting the design of transformers. To build on this theory, this paper analyzes a repository of popular transformer toys. Transformer toys are chosen for this study because of their richness in displaying a variety of kinematic aspects of transformation. Through this process, new definitions to describe transformation are garnered and a set of guidelines are developed to further aid designers. The empirical data set of transformer toys is rich in information and provides a basis for application to other fields, such as robotics and consumer products. These insights, in conjunction with the use of storyboarding, create a new method of designing transformers. This paper presents the method and concludes with a validation exercise in the creation of a new transformer toy.

The Creation

Two-stage liver transplantation (LT) has been reported for cases of fulminant liver failure that can lead to toxic hepatic syndrome, or massive hemorrhages resulting in uncontrollable bleeding. Technically, the first stage of the procedure consists of a total hepatectomy with preservation of the recipient's inferior vena cava (IVC), followed by the creation of a temporary end-to-side porto-caval shunt (TPCS). The second stage consists of removing the TPCS and implanting a liver graft when one becomes available. We report a case of a two-stage total hepatectomy and LT in which a temporary end-to-end anastomosis between the portal vein and the middle hepatic vein (TPMHV) was performed as an alternative to the classic end-to-end TPCS. The creation of a TPMHV proved technically feasible and showed some advantages compared to the standard TPCS. In cases in which a two-stage LT with side-to-side caval reconstruction is utilized, TPMHV can be considered as a safe and effective alternative to standard TPCS.

Crowd noise forms an integral part of a live sports experience. In the post-COVID era, when live audiences are absent, crowd noise needs to be added to the live commentary. This paper exploits the correlation between commentary and crowd noise of a live sports event and presents an audio stylizing sports commentary method by generating live stadium-like sound using neural generative models. We use the Generative Adversarial Network (GAN)-based architectures such as Cycle-consistent GANs (Cycle-GANs) and Mel-GANs to generate live stadium-like sound samples given the live commentary. Due to the unavailability of raw commentary sound samples, we use end-to-end time-domain source separation models (SEGAN and Wave-U-Net) to extract commentary sound from combined recordings of the live sound acquired from YouTube highlights of soccer videos. We present a qualitative and a subjective user evaluation of the similarity of the generated live sound with the reference live sound.

The paper presents the research results concerning the end devices of multimedia paths. It is focused on the spectral characteristics of human vision, which are basic for the creation of light-to-signal converters. The influence of changes in the spectral characteristics of the sensitivity of the converters on the color rendition in the end-to-end multimedia path has been investigated. Changes in the spectral characteristics of the transducers caused by the refined spectral characteristics of CIE06 vision, supplemented with previously unknown characteristics of vision (ipRGC model), as well as one of the possible variants of color perception impairment (data of Prof. M. Neitz) have been considered. An algorithm has been presented, which allows calculating the spectral characteristics for new and promising light-to-signal converters, depending on the spectral characteristics of vision properties. Analytical expressions have been proposed, which makes it possible to correct the color signals of the existing light-to-signal converters to ensure the required level of color rendering quality in the end-to-end path. Estimates of the effectiveness of the proposed algorithm have been given.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
