“…Also, a user can perform interactions, such as zooming and moving virtual objects and drawing lines in virtual spaces. Kaufmann et al proposed a system consisting of a smartphone and a small projector that can project images so that only part of a larger information space is seen through a peephole [7]. This system obtains its own 3D poses by using the gyro sensor built into the smartphone, and the images to be projected are generated using the pose information of the smartphone.…”

“…To solve this problem, there have been studies on peephole interaction using a handheld projector [6,7]. By changing the image to be projected according to the projector's position and direction, it is possible to extend the display area.…”

In our previous work, we proposed a user interface in which a user wears a projector and a depth camera on his or her head and performs touch operations on an image projected on a flat surface. By using the head-mounted projector, images are always projected in front of the user in the direction of the user's gaze. The image to be projected is changed according to the user's head pose so as to fix the superimposed image on the surface, which realizes a large effective screen size. In this paper, we conducted an experiment for evaluating the accuracy of registration by measuring the positional and rotational errors between the real world and the superimposed image using our experimental system. As a result, the mean absolute errors of translation were about 10 mm when the user stopped his head, and the delay was estimated to be about 0.2 s. We also discuss the limitations of our prototype and show the direction of future development.

“…Peephole navigation was made on a prototype consisting of a LG Optimus 3D (Android 2.2) connected via HDMI to a MicroVision SHOWWX+ laser pico projector (800480 pixels) attached to its back. Inertial sensors were used to implement the peephole interface (as described in [7]). A cross-hair cursor at the center of the peephole allowed users to select items (confirmed by a tap on the screen).…”

Smartphones are useful personal assistants and omnipresent communication devices. However, collaboration is not among their strengths. With the advent of embedded projectors this might change. We conducted a study with 56 participants to find out if map navigation and spatial memory performance among users and observers can be improved by using a projector phone with a peephole interface instead of a smartphone with its touchscreen interface. Our results show that users performed map navigation equally well on both interfaces. Spatial memory performance, however, was 41% better for projector phone users. Moreover, observers of the map navigation on the projector phone were 25% more accurate when asked to recall locations of points of interest after they watched a user performing map navigation.
