Description:
Touch is a very natural and intuitive way for people to interact. However, typical touchscreen technology, such as that commonly found in kiosks and interactive whiteboards, are limited to detecting only a single point of contact at a time. This makes them completely unsuitable for enabling touch interaction on larger displays designed to accommodate multiple users, since any one touch will prevent any others from being registered at the same time.
The Multi-Touch Interaction Wall is a 16-feet long by 3-feet high rear-projection surface that has the unique capability of detecting multiple points of contact simultaneously. At this Emerging Technologies installation, we demonstrate an assortment of innovative applications and user interfaces that leverage this unique device.
Multi-touch sensing enables the user to finally interact with both hands at once, as well as to employ more complex chording gestures, promising great improvements in usability, intuitiveness, and efficiency. Such a system also inherently accommodates multiple users simultaneously, a point that we emphasize through the horizontal scale of this installation, which results in a very inviting environment for multiple attendees to be able to walk up to and interact with the display.
Multi-touch is one of the most exciting fronts in user interface research, and will almost certainly be a component of how we interact with machines in the future.
