Abstract: Nowadays interactive displays are capable of offering a great variety of interactions to users thanks to advancement of ubiquitous computing technologies. Although many methods of interactions have been researched, usability of the devices is still limited and they are offered only to a single user at a time. This paper proposes a spatial multi-interaction interface that can provide various interactions to many users in an ambient environment. An interaction surface is created for users to interact through IR-LEDs Array Bar. The coordinate information of the hand is extracted by detecting the area of the hand of a user in the interaction surface. Then users can experience various interactions through “spatial touches” on the interaction surface. In our paper a usability evaluation is carried out for our new interface which gives the emphasis to the interaction interface. The usability of our new interface is shown to be significantly better through statistical testing using t-testing. Finally, users can perform various interactions with natural hand motions only without the aid of devices that have to be operated manually.
