Visualising and revitalising traditional Chinese martial arts Visitors' engagement and learning experience at the 300 years of Hakka Kungfu

Purpose The purpose of this paper is to examine how the emergent 3D interactive media technologies are used as a viable tool for enhancing visitors' overall experiences at an exhibition entitled, 300 Years of Hakka Kungfu - Digital Vision of Its Legacy and Future (Hakka Kungfu Exhibition) - presented and co-organized by the Intangible Cultural Heritage Office of Hong Kong, International Guoshu Association and the School of Creative Media, City University of Hong Kong. Design/methodology/approach A questionnaire survey in both online and paper-based formats was used for identifying visitors' experiences in the interactions with the multimedia technologies. For this research study, a questionnaire, consisting of 26 items, was set out to measure the visitors' experiences at the Exhibition. Since the Exhibition was about presenting a centuries-old Chinese cultural heritage, Hakka Kungfu via the use multimedia technologies, in the context of establishing a dialogue between the past and present, the researchers included questionnaire items that were devoted to enquire about the level of understanding, knowledge and enjoyment, and visitors' new knowledge about Hong Kong history and culture was successfully disseminated to the respondents at the end of the questionnaire. Findings A total of 209 completed questionnaires were collected at this Hakka Kungfu Exhibition. The findings reveal that the exhibits did attract people at all ages. This Exhibition gave the visitors a sense of interest and wonder in the object and information presented in the Exhibition. Findings of this study also reveal that this Exhibition has successfully attracted a large number of female visitors, as well as visitors who have never taken any martial arts training. In addition, visitors' Exhibition experience was found to be memorable, as well as enjoyable. Furthermore, visitors' experience within the Exhibition suggested that it was entertaining, as well as educational. By creating a long-lasting impact on the minds of these Exhibition visitors about the connections between and relevance of traditional Chinese Kungfu, their collective cultural identity, as well as the contemporary society we live in. The Exhibition exemplified the successful integration of the presentation of Kungfu as a form of cultural heritage with engagement-creating technology, in which technology is unobtrusive but effective. Originality/value Although it is already a global trend for the museums to integrate multimedia technologies into their exhibitions, research on the situation and feedback of multimedia technology used in the museum exhibitions in Hong Kong is scarce as well as scattered. Findings of this study could help identify various factors involved in audience participation, thereby exploring the possibility of building a contact point/space for traditional Chinese Kungfu as an intangible cultural heritage, via the integration of the latest media technologies. In particular, the development of multimedia technologies has become increasingly important to museums, and museum professionals have been exploring how digital and communication technologies can be developed to offer visitors a more interactive, personalized museum experience. In general, despite the growing interest in deploying digital technology as interpretation devices in museums and galleries, there are relatively few studies that examine how visitors, both alone and with others, use new technologies when exploring the museum contents.

Transforming scholarship in the archives through handwritten text recognition Transkribus as a case study

Sofia Ares Oliveira, Frédéric Kaplan

Purpose An overview of the current use of handwritten text recognition (HTR) on archival manuscript material, as provided by the EU H2020 funded Transkribus platform. It explains HTR, demonstrates Transkribus, gives examples of use cases, highlights the affect HTR may have on scholarship, and evidences this turning point of the advanced use of digitised heritage content. The paper aims to discuss these issues. Design/methodology/approach This paper adopts a case study approach, using the development and delivery of the one openly available HTR platform for manuscript material. Findings Transkribus has demonstrated that HTR is now a useable technology that can be employed in conjunction with mass digitisation to generate accurate transcripts of archival material. Use cases are demonstrated, and a cooperative model is suggested as a way to ensure sustainability and scaling of the platform. However, funding and resourcing issues are identified. Research limitations/implications - The paper presents results from projects: further user studies could be undertaken involving interviews, surveys, etc. Practical implications - Only HTR provided via Transkribus is covered: however, this is the only publicly available platform for HTR on individual collections of historical documents at time of writing and it represents the current state-of-the-art in this field. Social implications The increased access to information contained within historical texts has the potential to be transformational for both institutions and individuals. Originality/value This is the first published overview of how HTR is used by a wide archival studies community, reporting and showcasing current application of handwriting technology in the cultural heritage sector.

SOI mixed-mode design techniques and case studies

Marija Blagojevic

Since the emergence of Silicon On Insulator (SOI) technology the research activities have been concentrated on a detailed analysis of SOI devices and their use in different application fields (low-voltage, low-power circuits, high temperature electronics, digital circuits, etc.). The present thesis deals with low-voltage, low-power mixed-mode design using a SOI technology. The goal is to establish the concepts that allow one to design SOI mixed-mode circuits, and to apply these concepts to the design of fully depleted (FD) and partially depleted (PD) SOI circuits and systems. Two studies have been realized in the scope of this work: a Hall sensor based microsystem design using an experimental FD SOI technology a DRAM design using capacitor-less 1T floating-body PD SOI memory cells. At the beginning of this thesis, two major types of SOI devices are introduced, namely FD and PD devices. The most important properties of these devices are then presented and compared to those of CMOS bulk devices. A design methodology based on design retargeting from bulk to SOI technology is further proposed. This methodology is developed with the aim of being implemented for the design of FD SOI circuits. It consists in using the same device dimensions and bias currents for the bulk and the corresponding FD SOI design. The analysis performed proves that such an approach permits one to obtain better circuit performances using the FD SOI technology. The EKV model is chosen for Spice simulations. For that purpose the extraction of the EKV intrinsic parameters has been performed for the experimental 0.5 μm FD SOI technology. The EKV model card obtained from transistor measurements is implemented straightforwardly for circuit simulations. The first study presented in this thesis is an FD SOI Hall sensor front-end for energy measurement. The mixed-mode microsystem design is completely based on the proposed design methodology. The system level solutions are also included, such as the spinning-current method that serves for reduction of the offset and low frequency noise of the analog front-end, and a high resolution analog-to-digital conversion technique. The integrated microsystem is entirely functional. Furthermore, according to the existing literature, this integrated circuit is the first microsystem completely realized using FD SOI technology. The overall system error that is obtained is less than 1.5 %. During the second part of this work, a novel sensing scheme that exploits an automatic reference generation based on successive approximations has been developed for the PD SOI capacitor-less 1T DRAM. The 1T DRAM reference current is generated by an adjustable current source. The electrical calibration of the reference current is performed using a digital-to-analog converter and successive approximations algorithm. The proposed scheme is evaluated in a 2 kb test chip. The circuit integrated using PD SOI technology contains a 2 kb 1T memory array, as well as automatic reference generators and peripheral circuits. The automatic reference generator comprises current mode sense amplifier, M/3M converter, and successive approximations register. All blocks implemented in the test chip are described in detail, and PD SOI design issues are discussed. A number of experimental results demonstrate the potential of the PD SOI 1T DRAM for future embedded DRAM applications. The measured retention time under holding conditions is higher than 1s. In the continuous read mode, a few hundreds of the read cycles can be performed without a refresh operation. The test chip has a measured access time of 25 ns with a read cycle time of 70 ns.
