Popular Abstract in English Swedish theatre around 1970 was socially committed and experimental, in a vibrant time of new forms within an ideological climate.

In the present paper we report on the design decisions and the field test results of an inclusive mobile tourist guide app, the Time Machine.

To emphasize the eyes-free use, 9 of 11 test users recruited had severe
