Shopping is difficult for people with motor impairments. This includes online shopping. Proprietary software can emulate mouse and keyboard via head tracking. However, such a solution is not common for smartphones. Unlike desktop and laptop computers, they are also much easier to carry indoors and outdoors. To address this, we implement and open source button that is sensitive to head movements tracked from the front camera of iPhone X. This allows developers to integrate in eCommerce applications easily without requiring specialized knowledge. Other applications include gaming and use in hands-free situations such as during cooking, auto-repair. We built a sample online shopping application that allows users to easily browse between items from various categories and take relevant action just by head movements. We present results of user studies on this sample application and also include sensitivity studies based on two independent tests performed at 3 different distances to the screen.

The South African cabinet adopted policy recommendations from the Government Information Technology Officer's Council pertaining to Free and Open-Source Software (FOSS). Even though the South African Cabinet has shown support for the use of FOSS through the enactment of a policy, the adoption of open source software in electronic records management seems to be slow. Proprietary software continues to be adopted and used by most public institutions, including local and provincial municipalities in South Africa. Therefore, this study aimed to investigate factors that may influence the adoption and use of FOSS for electronic records management by South African municipalities. The study adopted a qualitative research approach to collect data from 10 purposively selected municipalities in Gauteng. Data were analysed and presented thematically to address the research question. The findings of this study suggest that municipalities in Gauteng are not adopting FOSS for electronic records management as expected. This study established that top management support, reliability, affordability of the software, inadequate capability, contracts with proprietary software providers, organisational culture and organisational support are some of the factors that contributed to the low uptake when it comes to the adoption of Free and Open-Source Software by the municipalities.

The African continent has long benefited from adopting OSS in its private and public organizations that have changed their way of development, the use and how to acquire proprietary software. This frequency of adaptation does not appear to be in balance with the contribution to the OSS community. Using views from experienced software practitioners working in different organizations across two African countries it has been observed that neglected infrastructure, a wide availability of proprietary software and misconceptions of a clear meaning of Open Source Software across Africa have been an obstacle towards the participation in the OSS technology in the global network.

This chapter serves as an introductory overview of Open Source Software (OSS) and the Open Source movement. It is geared primarily for technical communicators. To provide a thorough overview, this chapter defines OSS, explains how OSS works in comparison to proprietary software, looks at the history of OSS, and examines OSS licensing types, applications in business, and overall strengths and weaknesses when compared to proprietary software. Lastly, it evaluates the practical potential of OSS as well as emerging and future trends relating to it. From this general but thorough overview the intended audience of technical communicators will gain the solid understanding needed to work successfully in an academic or professional environment where OSS continues to grow in popularity, spurring more organizations to rely on it or the Open Source ideas that have inspired and continue to drive its creation and growth.

Programming a rich Internet application (RIA) in any Web environment is the goal of Laszlo Systems. The open source software, OpenLaszlo Presentation Server, allows a user to run, on any device, applications that blend to perfection a user-centered design. It facilitates development from the basic levels such as creating forms, menus and other components for a website, up to high-level tasks like focusing on the attention of the user, to easily create, for example, an e-commerce website, a full management back office or a trip booking site, all this using animations comparable to those created with proprietary software.

Abstract. AtChem is an open source zero-dimensional box-model for atmospheric chemistry. Any general set of chemical reactions can be used with AtChem, but the model was designed specifically for use with the Master Chemical Mechanism (MCM, http://mcm.york.ac.uk/). AtChem was initially developed within the EUROCHAMP project as a web application (AtChem-online, https://atchem.leeds.ac.uk/webapp/) for modelling environmental chamber experiments; it was recently upgraded and further developed into a standalone offline version (AtChem2) which allows the user to run complex and long simulations, such as those needed for modelling of intensive field campaigns, as well as to perform batch model runs for sensitivity studies. AtChem is installed, set up and configured using semi-automated scripts and simple text configuration files, making it easy to use even for non-experienced users. A key feature of AtChem is that it can easily be constrained to observational data which may have different timescales, thus retaining all the information contained in the observations. Implementation of a continuous integration workflow, coupled with a comprehensive suite of tests and version control software, makes the AtChem codebase robust, reliable and traceable. The AtChem2 code and documentation are available at https://github.com/AtChem/, under the open source MIT license.

The contribution of the flocculus region of the cerebellum to horizontal gaze pursuit was studied in squirrel monkeys. When the head was free to move, the monkeys pursued targets with a combination of smooth eye and head movements; with the majority of the gaze velocity produced by smooth tracking head movements. In the accompanying study we reported that the flocculus region was necessary for cancellation of the vestibuloocular reflex (VOR) evoked by passive whole body rotation. The question addressed in this study was whether the flocculus region of the cerebellum also plays a role in canceling the VOR produced by active head movements during gaze pursuit. The firing behavior of 121 Purkinje (Pk) cells that were sensitive to horizontal smooth pursuit eye movements was studied. The sample included 66 eye velocity Pk cells and 55 gaze velocity Pk cells. All of the cells remained sensitive to smooth pursuit eye movements during combined eye and head tracking. Eye velocity Pk cells were insensitive to smooth pursuit head movements. Gaze velocity Pk cells were nearly as sensitive to active smooth pursuit head movements as they were passive whole body rotation; but they were less than half as sensitive (≈43%) to smooth pursuit head movements as they were to smooth pursuit eye movements. Considered as a whole, the Pk cells in the flocculus region of the cerebellar cortex were <20% as sensitive to smooth pursuit head movements as they were to smooth pursuit eye movements, which suggests that this region does not produce signals sufficient to cancel the VOR during smooth head tracking. The comparative effect of injections of muscimol into the flocculus region on smooth pursuit eye and head movements was studied in two monkeys. Muscimol inactivation of the flocculus region profoundly affected smooth pursuit eye movements but had little effect on smooth pursuit head movements or on smooth tracking of visual targets when the head was free to move. We conclude that the signals produced by flocculus region Pk cells are neither necessary nor sufficient to cancel the VOR during gaze pursuit.
