Work on interactive tabletops and surfaces has focused mostly on two-dimensional issues, such as multi-finger gestures and tangible interaction. Interesting as it is, however this picture is missing several dimensions. I will describe work on 2D and 3D semi-immersive environments and present novel on-and-above-the-surface techniques based on bi-manual models to take advantage of the continuous interaction space for creating and editing 3D models in stereoscopic environments. I will also discuss means to allow for more expressive interactions, including novel uses of sound and combining hand and finger tracking in the space above the table with multitouch gestures on its surface continuously. These combinations can provide alternative design environments and allow novel interaction modalities.

Also, As prof-of-concept for person to device interactions,
We devised the role of the moderator of the meeting,
when in close proximity to a wall display, the person
assuming that role can perform actions that relate to
every participant.
People like to meet in person,
and when they do,
they communicate in different manners besides verbally.
Edward Hall states that space and distance play key roles in the way people communicate.
Therefore, Proxemics are a non-verbal type of communication and can be exploited in the context of virtual meetings.
We use the Proxemic Distances model to provide the necessary knowledge
to bring social interactions into virtual meetings.
To provide, the means for people to implicitly and automatically start
remote interactions just by getting together.
Avatars and telepresence robots are a poor representation of people,
and they contribute to the lack of presence
Our model do not play by the same rules
The question is not how well we represent people.
The important
part of our research is the representation of interactions occurring around the room.
We use a ceiling mounted projector to display floor circles which account for the
position of all eery space participants.
In this way, every one becomes aware of their intimate space (the inner circle)
and their personal space (the outer ring).
The dimensions follow the proxemic distances proposed by Edward Hall.
In this figure, we display two people forming a social bubble,
and performing a collaborative task.
Again, there is no need for high definition avatars or video for people to know about the presence of others.
