Urban augmentation in Koskela hospital area EIT ICT Street Smart pilot

A new way of seeing your environmentHelsinki City Planning center, VTT and Forum Virium Helsinki collaboration projectUrban augmentation was piloted as a part of citizen participation in the Koskela hospital area planning

Koskela Hospital area pilot

There were 4 different construction plans for Koskela Hospital area People had the possibility to get familiar with the new plans in the Helsinki City Planning department internet pages and newsletter. The test group were introduced the new plan during a walking tour in the area and through an augmented reality application (which could be used in a tablet or other smart devices). There were 21 participants and they were divided in to two different groups to observe the plansAfter the walking tour people could comment and discuss the different construction designs with the architectsThe urban augmentation pilot received positive feedback from the participants. People appreciated the different plans of which they could pick their favorites.

The pilot setting

Most of the people appreciated the green

areas and parks around the Koskela hospital area

A tram connection to the city and biking routes were important to the

participants

Test group on the field

Results of the user study The users were given a set of questions Questions/ Arguments that they answered in multiple choice.

About half of the respondents felt that the application helped to conceptualize the construction plansMost of the users felt that the application was easy to use and it functioned well technicallyMore than half of the users felt that the application was not natural to useThe application added to the traditional ways of visualizing thingsThe designs were too rough for people to evaluate them

Results of the user studyThe best qualities and features of the application:

Other comments and ideas:

The application offered a good overview of the future neighbourhoodIt also helped to conceptualize the use of space, the placement of the buildings and the hight differences between different buildings

• Bigger screen for the application or an app for your phone.(People felt that the application was unfinished)

• More detailed and accurate construction designs

• Some people questioned the usefulness of the application

• Designs of the buildings could be more diverse (for example the coating of the buildings)

You couldn`t see which of the old hospital buildings would be visible to the streets or

how close to the streets the new buildings are going to be

built

The app could work on smartphones. Hologram

projection? (SciFi but it could work)

A good overall view

of the buildings

Most of the people said they are going to participate in the online conversation ( 97 comments in the conversation)

Comments from the City of HelsinkiThe pilot was produced in tight collaboration with Helsinki City Planning Center as part of their activities of involving the citizens.

The augmented reality helped to visualize the used space and proportions of the city space. The application has its limitations and it is not meant for every situation. For example the trees around Koskela area limited the use of application in this pilot”, says Antti Varkemaa,Architect, project manager from the Helsinki City Planning Department.
