Ubiquitous Interaction (UIx)


Ubiquitous Interaction studies the design, development and evaluation of interactivity with users in ubiquitous and mobile computing systems. The research is carried out coupling in-depth user studies with design in the area of novel interfaces. The goal is to contribute to technology development efforts by deepening understanding of human and design perspectives. Currently, research is conducted in different areas: multitouch displays, adaptivite and affective interfaces, multimodal interaction, exploratory search and social computing. Application areas range from sustainability and environmental awareness, home computing, walk-up-and-use display, information exploration, art and culture, scientific and knowledge work.

The group conducts part of the research in the Aalto University campus.

In the University of Helsinki in Kumpula, Department of Computer Science the group offers teaching and research in Interactive Systems and Human-computer interaction.

ForcePhone is a mobile synchronous haptic communication system. During phone calls, users can squeeze the side of the device and the pressure level is mapped to vibrations on the recipient’s device. The pressure/vibrotactile messages supported by ForcePhone are called pressages. The paper can be downloaded here.


MapLens overlays a real map with icons that identify game clues and photos. Users can select icons and zoom any desired image to full-screen for closer inspection. A you are here icon shows the position of the user in the map. MapLens runs at interactive frame rates of 16-20Hz on a Nokia N95.


CityWall is a multitouch display set in Lasipilatsi, city square of downtown Helsinki. People tag images which are then placed on the display via flickr. Citywall allows multiple users to interact with the content in an intuitive, friendly and often performative manner at this large public display. Developed in IPCity. Link »


Multimodal flexibility index is a method developed to assess how flexibly users are able to allocate their sensory capacities to other things while using a mobile device. Link »

PuppetWall, a multi-user, multimodal system intended for digitally augmented puppeteering. This application allows natural interaction to control puppets and manipulate playgrounds comprised of background, props and puppets. PuppetWall utilizes hand movement tracking, a multi-touch display and emotion speech recognition input for interfacing. Here we document the technical features of the system and an initial evaluation.
