Joseph Priestley: the man who drew time

The Joseph Priestley House Museum at Northumberland, Pennsylvania became interested in Priestley's pioneering timelines as a complement to his better known work in chemistry, electricity, biblical scholarship and political radicalism. Boyd Davis wrote this short article for the newsletter published by the Friends of the museum. The article concentrates on the connections between Priestley, his French contemporary Barbeu-Dubourg and Benjamin Franklin at the time of the struggle for American Independence, and Priestley's two key chronographic innovations: the use of drawn or printed lines to represent the duration of lives, and the associated use of dots to show when the dates of such lives are in doubt or dispute.

Time in Perspective: a visual approach to models of time

Geographical representations of topographical space come in many shapes and are a regular topic of discussion. The depiction of the invisible and maybe even illusory concept of time on the other hand, remains largely unchanged and undisputed. A uniform and arithmetic model of time fits well with the rigid structure of digital data, which might be why it has been widely adopted within HCI. In our proposal, we will present historic and contemporary approaches that offer alternative perspectives on the visual representation of time. Keywords: timeline, chronographics

‘To see at one glance all the centuries that have passed’ - early visualisations of historical time

This chapter focuses on the visualisation of historical time, illustrated by key examples from the eighteenth century when the modern timeline was invented. We are fortunate in having not only surviving examples of printed timelines from the period but also explanations written by their makers, revealing the ambitions they had for visualisation. An important divergence is evident, between those who want to use rhetorical visual metaphors to tell a graphical story, and those who prefer to let the data ‘speak for itself’, allowing patterns to emerge from the distribution of data points across a surface.

Do challenge, task experience or computer familiarity influence the learning of historical chronology from virtual environments in 8–9 year old children?

Studies examined the potential use of Virtual Environments (VEs) in teaching historical chronology to 127 children of primary school age (8–9 years). The use of passive fly-through VEs had been found, in an earlier study, to be disadvantageous with this age group when tested for their subsequent ability to place displayed sequential events in correct chronological order. All VEs in the present studies included active challenge, previously shown to enhance learning in older participants. Primary school children in the UK (all frequent computer users) were tested using UK historical materials, but no significant effect was found between three conditions (Paper, PowerPoint and VE) with minimal pre-training. However, excellent (error free) learning occurred when children were allowed greater exploration prior to training in the VE. In Ukraine, with children having much less computer familiarity, training in a VE (depicting Ukrainian history) produced better learning compared to PowerPoint, but no better than in a Paper condition. The results confirmed the benefit of using challenge in a VE with primary age children, but only with adequate prior familiarisation with the medium. Familiarity may reduce working memory load and increase children’s spatial memory capacity for acquiring sequential temporal-spatial information from virtual displays.

Human-Centric Chronographics:Making Historical Time Memorable

A series of experiments is described, evaluating user recall of visualisations of historical chronology. Such visualisations are widely created but have not hitherto been evaluated. Users were tested on their ability to learn a sequence of historical events presented in a virtual environment (VE) fly-through visualisation, compared with the learning of equivalent material in other formats that are sequential but lack the 3D spatial aspect. Memorability is a particularly important function of visualisation in education. The measures used during evaluation are enumerated and discussed. The majority of the experiments reported compared three conditions, one using a virtual environment visualisation with a significant spatial element, one using a serial on-screen presentation in PowerPoint, and one using serial presentation on paper. Some aspects were trialled with groups having contrasting prior experience of computers, in the UK and Ukraine. Evidence suggests that a more complex environment including animations and sounds or music, intended to engage users and reinforce memorability, were in fact distracting. Findings are reported in relation to the age of the participants, suggesting that children at 11–14 years benefit less from, or are even disadvantaged by, VE visualisations when compared with 7–9 year olds or undergraduates. Finally, results suggest that VE visualisations offering a ‘landscape’ of information are more memorable than those based on a linear model. Keywords: timeline, chronographics

Scholarly chronographics: can a timeline be useful in historiography?

Our paper is concerned with the visualisation of historical events and artefacts in the context of time. It arises from a project bringing together expertise in visualisation, historiography and software engineering. The work is the result of an extended enquiry over several years which has included investigation of the prior history of such chronographics and their grounding in the temporal ontology of the Enlightenment. Timelines - visual, spatial presentations of chronology - are generally regarded as being too simple, perhaps too childish, to be worthy of academic attention, yet such chronographics should be capable of supporting sophisticated thinking about history and historiography, especially if they take full advantage of the capabilities of digital technologies. They should enable even professional academic historians to 'make sense' of history in new ways, allowing them insights they would not otherwise have achieved. In our paper we highlight key findings from the history of such representations, principally from the eighteenth and nineteenth centuries, and show how, in a project to develop new digital chronographics for collections of cultural objects and events, we have explored new implementations of the important ideas we have extracted about timewise presentation and interaction. This includes the representation of uncertainty, of relations between events, and the epistemology of time as a 'space' for history. We present developed examples, in particular a chronographic presentation of a large database of works by a single author, a composer, and discuss the extent to which our ambitions for chronographics have been realised in practice.

Graphic design and modernisation in Greece, 1945-1970

The primary aim of this work is to give voice to the silent history of graphic design in Greece, long uncharted and undocumented in both the international forum and the local design community. This study focuses on the professional modernisation of graphic design and its role in providing the means for change in Greek society. The research is supported by interdisciplinary analysis of commercial advertisements, posters, leaflets and magazines, as well as other supporting documentation, in the historical and cultural context of Athens, Greece from 1945 to 1970. The time examined was a transitional and vociferous period in the history of Greece, one of intense and rapid economic modernisation during the post-Second World War decades from the mid-1940s to 1970. This was a time when, along with broader changes in the social, economic and political life of Greece, important developments in design education, print technology, and professional organisation marked a new age for graphic design, as a profession emerging from the broader ‘graphic arts’ field (inclusive of both technological and creative processes) and claiming autonomy over the more established fine arts sector. All four chapters deal with modernisation in relation to the assumed divisions of traditional/modern, continuity/change, centre/periphery. Main areas of investigation are: trade organisation, graphic design education, advertising and urbanisation, electricity and tourism promotion. This research offers a view of the ways the ‘modern’ and the condition of modernity were experienced in the case of Greece through certain applications of graphic design and its agents of influence: graphic designers, artists, managers, publishers, the state and private entrepreneurs. The research benefited significantly from a number of interviews with design professionals and related individuals. The present endeavour has a modest aim: to enable understanding of how and why Greek graphic design at the time came to be, and to stress the validity of the visual as a means of historical documentation.

Piñatex, the design development of a new sustainable material

This is a research project by practice, which firstly develops a new material invention derived from natural fibres extracted from waste pineapple leaves; secondly it articulates the contemporary designer’s role in facilitating sustainable solutions through: Insights from my own material invention, PiñatexTM, which integrates the materiality of design with the immateriality of concepts and values Developing a visual model of mapping I began with these questions: ‘What are the challenges in seeking to make a new and sustainable material from the waste products of pineapple agriculture in the Philippines?’ and ‘How can a design practice link elements of materiality (artifacts) with immaterial elements (value systems) in order to improve sustainable social and economic development?’ Significant influences have been the work of Papanek1 (2003), Hawken2 (1999) and Abouleish3 (2008) and in particular the ethical business model initiated by McDonough and Braungart in Cradle to Cradle®4 (2002). My own research project is inspired by the Cradle to Cradle® model. It proposes the development of a new material, PiñatexTM which is derived from natural fibres extracted from waste pineapple leaves and could be used in a wide variety of products that are currently fabricated in leather or petroleum-based materials. The methods have comprised: Contextual reviews; case studies (SEKEM, Cradle to Cradle® and Gawad Kalinga); practical experiments in the field of natural fibres, chemistry, product development, manufacturing and prototyping, leading to an invention and a theoretical model of mapping. In addition, collaboration has taken place across scientific, technological, social, ecological, academic and business fields. The outcome is a new material based on the synchronicity between the pineapple fibres, polymers, resins and coatings specially formulated. The invention of the new material that I developed as a central part of this research by practice has a patent in the national phase (PCT/GB 2011/000802) and is in the first stages of manufacturing, commercial testing and further design input (Summer 2014). The contribution to knowledge is firstly the material, PiñatexTM, which exhibits certain key qualities, namely environmentally non-toxic, biodegradable, income-generating potential and marketability. This is alongside its intrinsic qualities as a textile product: aesthetic potential, durability and stability, which will make it suitable for the accessories, interiors and furnishing markets. The theoretical mapping system Upstream and Downstream forms a secondary contribution.
