Abstract
Specialet undersøger, hvordan par af personer samarbejder med en specialudviklet Dual Sided Interface—en eksperimentel skærm, der kan læses samtidig fra begge sider. I et laboratoriestudie deltog 11 testteams med to personer i hver, som blev bedt om at læse og forholde sig til datadiagrammer (linje-, søjle-, bjælke- og cirkeldiagrammer), hvor indholdet kunne ses fra begge retninger og til tider i spejlvendt form. Sessionerne blev videofilmet, og de observerede handlinger blev kvantificeret og grupperet, fx hvor ofte deltagerne udførte en vende-operation på et vindue for at ændre orienteringen. Det blev desuden observeret, at nogle havde næsten ingen problemer med at læse spejlvendt indhold. Den specialudviklede Dual Sided Interface havde ikke ægte multipoint-input; i stedet styrede to mus en enkelt delt markør. Dette kan have reduceret interaktionsraten sammenlignet med et system med flere uafhængige pegere. Rapporten konkluderer, at der er behov for yderligere forskning for at vurdere den praktiske nytte af en dobbelt-sidet brugerflade.
This thesis explores how pairs of people collaborate when using a custom Dual Sided Interface—an experimental display designed to be read from both sides at the same time. In a lab study, 11 two-person teams were asked to read and engage with data charts (line, column, bar, and pie) where the content was visible from both directions and sometimes in mirrored form. Sessions were video-recorded, and observed behaviors were quantified and grouped, such as how often participants performed a window flip to change orientation. It was also noted that some people had little trouble reading mirrored content. The custom Dual Sided Interface did not provide true multipoint input; instead, two mouse devices controlled a single shared cursor. This may have reduced the rate of interaction compared with a system that supports multiple independent pointers. The report concludes that more research is needed to assess the practical usefulness of a dual-sided interface.
