Abstract
“The important criterion for a graph is not simply how fast we can see a result;
rather it is whether through the use of the graph we can see something that would
have been harder to see otherwise or that could not have been seen at all.”
William S. Cleveland

When presenting graphs for people with visual impairments the solutions found
on the market today often present pure data values only. Overview is missing
and there is no possibility to get any additional information about the visual
content of the graph. Should we accept the fact that visually impaired persons
are only presented with the data or could they actually benefit from data represented
in graphical form?

When presenting graphs for people with visual impairments the solutions found
on the market today often present pure data values only. Overview is missing
and there is no possibility to get any additional information about the visual
content of the graph. Should we accept the fact that visually impaired persons
are only presented with the data or could they actually benefit from data represented
in graphical form?

The aim of this project was to investigate how to provide people with visual
impairments the best possible user experience when analyzing data in the business
intelligence program Qlik Sense. The research showed that it is possible to
convey an overview of the content in graphs with a synthetic speech solution.
The synthetic speech presents the purpose of the graph and key values as well as
the overall shape of the curve. In a future development it is possible to extend
the product to include voice recognition to allow the user to explore the data
and make own discoveries.

The project begun with a literature study to find previously conducted work
in the same field. To gather proper knowledge about what information users
find interesting, what they are looking for and how they can benefit from using
charts, a pilot study was initiated. The pilot study was performed by people
who have vision classified as normal. Further, persons from the target group, i.e.
people with visual impairments, were interviewed to receive an understanding
of what is missing from today’s low vision aids and solutions. These results
were used when creating a Low Fidelity prototype in an attempt to show how
to present visual data to a visually impaired user. The prototype was tested on
both sighted persons and persons from the target group. Results were then
collected and analyzed to create a foundation for the High Fidelity (Hi-Fi)
prototype that was developed to realize the design ideas. Finally, the Hi-Fi
prototype was evaluated through usability tests that resulted in the above-mentioned
conclusion. (Less)
Popular Abstract (Swedish)
“Det viktigaste kriteriet för en graf är egentligen inte hur fort vi kan se ett
resultat; det är snarare om vi genom användandet av en graf kan se något som
hade varit svårare att se annars eller som inte hade alls kunnat ses."
William S. Cleveland
Översättning: Celie Gunnarsson

De lösningar som finns på dagens marknad gällande presentation av grafer för
synskadade bygger ofta på ren presentation av enskilda värden. Översikt saknas
och det finns ingen möjlighet att få övrig information om det visuella innehållet
i grafen. Ska man som synskadad nöja sig med att endast få ta del av datan
eller ska man faktiskt kunna ha samma nytta av ett diagram som en seende
person?

De lösningar som finns på dagens marknad gällande presentation av grafer för
synskadade bygger ofta på ren presentation av enskilda värden. Översikt saknas
och det finns ingen möjlighet att få övrig information om det visuella innehållet
i grafen. Ska man som synskadad nöja sig med att endast få ta del av datan
eller ska man faktiskt kunna ha samma nytta av ett diagram som en seende
person?

Syftet med detta projekt var att undersöka hur man kan erbjuda personer med
synnedsättning den bästa möjliga användarupplevelsen då de analyserar data i
Business Intelligence-programmet Qlik Sense. Arbetet visade att det är möjligt
att förmedla en överblick av en grafs innehåll med hjälp av syntetiskt tal. Det
syntetiska talet kan då presentera grafens syfte, nyckeltal tillika formen på kurvan
som bildas. Vid framtida utveckling är det möjligt att utöka produkten så
att även röstigenkänning kan inkluderas. Detta skulle ge användaren en möjlighet
att på egen hand utforska datan och göra egna upptäckter.

Projektet inleddes med en litteraturstudie för att finna tidigare utfört arbete
inom samma område. För att insamla kunskap om vilken information som upplevs
som intressant, vad användare tittar efter och hur de kan ha nytta av
grafer utfördes även en pilotstudie. Försökspersonerna i denna studie utgjordes
av personer med syn klassificerad som normal. Vidare intervjuades personer ur
målgruppen, det vill säga personer med olika typer av synnedsättning, för att
skapa förståelse för vad som saknas i dagens hjälpmedel och lösningar. Dessa
resultat användes för att skapa en Low Fidelityprototyp i ett försök att visa
hur man skulle kunna presentera visuell data för en synskadad person. Prototypen
testades sedan, både utav seende personer och personer från målgruppen,
varefter resultatet sammanställdes och analyserades. Analysen användes för
att skapa en grund till den High Fidelityprototyp (Hi Fi-prototyp) som kom
att utvecklas ur designidéerna. Slutligen utvärderades Hi Fi-prototypen genom
användbarhetstester, vilka resulterade i ovan nämnda slutsats. (Less)
