Creation of a Virtual Museum for the Dissemination of 3D Models of Historical Clothing

Museums have been the main centers for the dissemination of cultural heritage throughout history. In recent years, they have been increasingly digitizing their content, so that it is now common for each museum to have free digital content available on the Web. This can be photographs of the works with detailed information or even objects created in three dimensions. It is also common to find virtual museums, which might be a representation of an existing museum that has been digitized or a museum created only in digital format. This paper describes the creation of a virtual museum of Spanish clothing from the 16th century, one that exists only in digital format, accessible from a computer or digital tablet. In order to create the museum, various documentation and drawings or pictures of the clothing of that time were studied. The costumes were then created in a specialized 3D costume-modeling program called Marvelous Designer. A 3D model of the exhibition hall was created in Blender, and finally, everything was assembled in the Unity videogame engine, where the interactive part was also added, allowing the virtual visitors to walk through the hall as if they were visiting a real museum.

Where to draw the line?

We often take people’s ability to understand and produce line drawings for granted. But where should we draw lines, and why? We address psychological principles that underlie efficient representations of complex information in line drawings. First, 58 participants with varying degree of artistic experience produced multiple drawings of a small set of scenes by tracing contours on a digital tablet. Second, 37 independent observers ranked the drawings by how representative they are of the original photograph. Matching contours between drawings of the same scene revealed that the most consistently drawn contours tend to be drawn earlier. We generated half-images with the most- versus least-consistently drawn contours and asked 25 observers categorize the quickly presented scenes. Observers performed significantly better for the most compared to the least consistent half-images. The most consistently drawn contours were more likely to depict occlusion boundaries, whereas the least consistently drawn contours frequently depicted surface normals.

Primary Progressive Aphasia: Use of Graphical Markers for an Early and Differential Diagnosis

Primary progressive aphasia (PPA) brings together neurodegenerative pathologies whose main characteristic is to start with a progressive language disorder. PPA diagnosis is often delayed in non-specialised clinical settings. With the technologies’ development, new writing parameters can be extracted, such as the writing pressure on a touch pad. Despite some studies having highlighted differences between patients with typical Alzheimer’s disease (AD) and healthy controls, writing parameters in PPAs are understudied. The objective was to verify if the writing pressure in different linguistic and non-linguistic tasks can differentiate patients with PPA from patients with AD and healthy subjects. Patients with PPA (n = 32), patients with AD (n = 22) and healthy controls (n = 26) were included in this study. They performed a set of handwriting tasks on an iPad® digital tablet, including linguistic, cognitive non-linguistic, and non-cognitive non-linguistic tasks. Average and maximum writing pressures were extracted for each task. We found significant differences in writing pressure, between healthy controls and patients with PPA, and between patients with PPA and AD. However, the classification of performances was dependent on the nature of the tasks. These results suggest that measuring writing pressure in graphical tasks may improve the early diagnosis of PPA, and the differential diagnosis between PPA and AD.

Differences in Levodopa Response for Progressive and Non-Progressive Micrographia in Parkinson's Disease

Background: Micrographia, one element of the dysgraphia of Parkinson's disease (PD), may be classified according to the presence or absence of a decremental pattern. The decremental form, progressive micrographia, is an expression of the sequence effect seen generally in bradykinesia. Its responsiveness to levodopa has not been evaluated kinematically.Objectives: Aim of this study is to investigate the difference in levodopa response for progressive and non-progressive micrographia.Methods: Twenty-four PD patients and 24 age-matched repeatedly wrote the letter e on a computerized digital tablet. PD patients performed the task two times, in a defined off state and again after levodopa. Scripts were classified as progressive micrographia (PDPM) or non-progressive micrographia (PDNPM) depending on whether a 10% decrement was seen between the first and final characters of a line of lettering.Results: While levodopa produced a similar response on the MDS-UPDRS motor scale for the two groups, the effect on the two types of micrographia was different. While writing speed improved significantly in both groups after levodopa, the responses were over twofold greater for PDNPM. Moreover, the decremental features of PDPM–in size, speed, and pen-pressure—were largely unaltered by a levodopa dose.Conclusions: Progressive micrographia is less responsive to levodopa. Our findings agree with research showing that the sequence effect of bradykinesia is relatively resistant to medication. Yet we did not find a weaker overall levodopa motor benefit. Caution is needed in the interpretation of such micrographia measurements for estimating drug responses.

A preliminary investigation assessing the basic digital capabilities of minimally verbal children on the autism spectrum with intellectual disability

Purpose Children with Autism Spectrum Disorder (ASD) can demonstrate a preference for using digital technologies which can represent a relative strength within the autism community. Such a strength would have implications for digitally mediated interventions and support for autism. However, research to date has not developed a methodology for assessing the capabilities of minimally verbal children on the autism spectrum with intellectual disability (ID) to use digital technology. Design/methodology/approach Six minimally verbal children with ASD and ID undertook an accessible assessment that identified what capabilities for interacting with a digital tablet device they could and could not demonstrate. Twelve brief assessments were demonstrated, including turning on the device, adjusting the volume, operating the camera, touching, tilting and rotating the screen. Findings Participants could be assessed on their digital capabilities. In this study, participants could largely touch and swipe the screen effectively and leave the app, but could not tilt and rotate the screen nor turn on the digital tablet device. Research limitations/implications While the numbers were small, the findings indicate that the digital capabilities of this group can usefully be assessed. Future research can use such assessments to highlight how intervention effectiveness and support can be enhanced by matching the digital capacities of minimally verbal children with ASD and ID to technological support. This is a preliminary study and a greater understanding of children’s prior experiences with technology will better inform how and which digital capabilities develop. Originality/value This is the first study to assess a range of basic capabilities for using digital tablet devices in minimally verbal children with ASD and ID.

N07 Patient reported outcome measures collected from patients using a digital tablet: early benefits

Background At a district general hospital (DGH) on the south coast of England the inflammatory bowel disease (IBD) nurse led service introduced an eHealth system in 2015 linked to the IBD registry but limited to access via a desktop limiting flexibility. In liaison with the IBD registry and the software developer the lead nurse instigated an upgrade to the system. This allows patients access both remotely and via a digital tablet in outpatients. Discussion is being had about the best way to collect patient reported outcome measures (PROMS) both for large data analyse and local patient benefit. This presentation of the first 3 months collection of the PROMS seeks to show the benefit of these data locally Methods PROMS were gathered from both Consultant and Nurse led clinics from July 2019 to the 22 October 2019. Patients were asked to fill in the IBD control PROM (this PROM forms part of the IBD registry Data set) on a tablet before entering the consultation room. Additionally a disease activity score either the Harvey Bradshaw Score (HBI) or the Simple Clinical Colitis activity index (SCCAI) is collected at the same time. These scores were then extracted from the system and evaluated using a descriptive data analysis approach. Results After Data cleansing 200 records are shown in Table 1 covering all disease sub-types. Fatigue was the most commonly reported complication of IBD in addition,126 patients who attended outpatients reported a wellness score of above 75 out of 100 isolating the wellness score from the PROM score allowed a comparison with the corresponding disease activity score in these patients and correlated in 95% of UC Patients and CD 84% (see Table 2). Conclusion Fatigue is a widely reported symptom of IBD as well as pain and anxiety or depression. These data confirm this trend but also present the first local population information for the IBD service at this DGH. When looking at the impact of these scores there is an opportunity to identify patients that may need medically optimising. The patients that remain could then be targeted with support services and a business case for counselling is now planned. In addition to this together with self-testing with IBDoc ® the PROMs and disease activity scores provide opportunity for remote management of some patients. These PROMs collected from patients using a tablet in outpatients at a DGH show promising value for service development.
