The sentiment was the same for the 2019 and 2020 South American eclipses that passed through Chile and Argentina. While a total solar eclipse is typically thought of as a striking visual phenomenon, it is not the only way to observe one, and for blind or low vision individuals, having an alternate medium to observe an eclipse is a necessity. LightSound is a low-cost, hand-held device that was originally developed for the 2017 North American eclipse. It has a very high-dynamic range sensor that converts light to sound in a process called sonification. The sound can be output to headphones or to a speaker during an event to make the entire event more accessible while capturing the dimming of the Sun in the form of sound. All documentation and software needed to build and use the LightSound are open source and free for download and modification. As the 2023 and 2024 North American solar eclipses approach, we aim to increase the number of LightSounds across the paths of totality so that the experiences can be more inclusive and accessible. In the astronomy community, we are holding a series of workshops through the American Astronomical Society to train new users to build and use the devices, but we hope to expand to a more general audience by connecting with organizations such as libraries, museums, national parks, girl/boy scouts, and others groups who we can help to build the necessary devices for communities and events in need. In addition to eclipses, the LightSound has exciting potential for use as a teaching tool at both K-12 levels and undergraduate levels and for raising awareness about sonification as a powerful and important analysis method in science.","PeriodicalId":49602,"journal":{"name":"Revista Mexicana de Astronomia y Astrofisica","volume":"191 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84393948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end I am active in a collaboration that is exploring the use of data sonification (converting data into sound) to enhance, validate, and accelerate discovery. The scope of our program is not limited to enabling blind and visually-impaired researchers to contribute to areas of research that were not previously accessible. Rather, we look also to the use of new multi-modal approaches that exploit the properties of sound to address mainstream challenges presented by trends in modern astrophysics. Using ‘real-life’ examples, I describe how we are ex- ploring time-series data, spectra, and multi-dimensional datasets mapped to a variety of sonic characteristics such as pitch, amplitude, waveform, pulse repeat rate, tone quality, and distortion and noise to provide addi- tional information on measurement uncertainties. I discuss the application of data sonification to high redshift galaxy research and to our coordinated multi-wavelength observational program to detect and follow up fast transient events. Finally, I outline current research directions involving touch screen and trackpad approaches to examine scatter-plot (non-linear) data representations, shape-based recognition, and the use of combined weighted harmonics to render the information content in multi-dimensional datasets as sound.","PeriodicalId":49602,"journal":{"name":"Revista Mexicana de Astronomia y Astrofisica","volume":"22 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75083758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, there are efforts to communicate astronomy to the visually impaired with the help of auditory perception and tactile perception. Screen reader applications are accessibility tools which help the visually impaired perceive images with the help of words. One of the disadvantages of screen reader is abstract astronomical concepts may be difficult to be recognized, especially for those who are visually impaired since childbirth. In this research, an image sonification program is designed as an alternative to screen reader applications to communicate astronomical images to the visually impaired using shape-approach sonification. The program was written using Python 3.8 programming language. The program is able to sonify shapes automatically and is also responsive to changes and differences in shapes. The result from program is a MIDI file which is then polished and exported using DAW to create music in the form of MP3 file. After a series of evaluation with the help of six people with visual impairment, we found that this method of sonification has potential as an alternative to the accessibility of astronomical images for the visually impaired with sufficient practice.","PeriodicalId":49602,"journal":{"name":"Revista Mexicana de Astronomia y Astrofisica","volume":"66 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87892604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studying astronomy goes beyond these wonders, which poses a challenge to students' knowledge and understanding of basic astronomical phenomena. The University of Cape Town has developed a series of research studies that probe the nature of student difficulties at a fine-grained level, in particular looking into how students conceive of astronomical distances which are beyond immediate human comprehension. The key experimental findings from this study were that as distances increased different modes of thinking were employed to make sense of them. The experimental findings could be explained by the embodied cognition framework which posits that the way we think (all thought) is ultimately grounded in infant sensory-motor experiences. In this case, the thinking template or image schema was suggested to be the \"source-path-goal\". Having identified the \"thinking\" framework allows for a research-based construction of learning activities that lead to sense-making. Thus, the notion of the Source-Path-Goal Thinking Template / Image Schema was used to create an activity that would trigger this mode of thinking for large-scale distances. Based on the current experimental findings that can be explained by an \"embodied cognition\" framework, learning activities were piloted that appear to have had a measure of success.","PeriodicalId":49602,"journal":{"name":"Revista Mexicana de Astronomia y Astrofisica","volume":"20 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87352612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
