Picture browsing and map interaction using a projector phone

Abstract

It is expected that projector phones (mobile phones with built-in pico projectors) will hit the market by 2010. Such phones provide a completely new way to display information and interaction techniques. The system presented in this paper allows the simulation of these projector phones as the real devices are not yet available. Through this, we demonstrate that it is currently possible to design, develop and evaluate applications for projector phones. The system supports three different modalities in order to compare when which display (phone display, projection) should be used. This prototype system was used for the implementation of two applications in order to test the advantages and disadvantages of projector phones for two common scenarios, picture browsing and map interaction. This demonstration paper describes the hardware used for the simulation of projector phones and the two developed prototypes. These prototypes were used for two different studies discussed in [1] and [2].

Confined projection on selected sub-surface using a robust binary-coded pattern for pico-projectors

“…This provides further motivation to our proposed scheme for the case where a mobile robot may encounter a totally new and unfamiliar place where it has to select a suitable projection surface and then make a confined projection in the available surface. Considerable work has also been published related to the design issues of pico-projectors such as placement of embedded projectors with respect to the smart phones [13,14], their brightness, size [15,16] and privacy of the personal data being shared [2]. Applications of projector phones for picture browsing and map interaction has been explored in [13,17].…”

“…Considerable work has also been published related to the design issues of pico-projectors such as placement of embedded projectors with respect to the smart phones [13,14], their brightness, size [15,16] and privacy of the personal data being shared [2]. Applications of projector phones for picture browsing and map interaction has been explored in [13,17]. Improving upon the work of Omni Touch [18] and Beamatron [19], Winkler et al [20] proposed a wearable projector system that constantly projects an ambient information display in front of the user.…”

Adaptive I/O Switching for Seamless Convergence of Smart Phones and External I/O Devices

“…The latest smartphones with Mobile HighDefinition Link (MHL, 2008) can connect them to a TV to watch videos and photos via High Definition Multimedia Interface (HDMI, 2009). Greaves et al (2008) uses a different approach using a projector to display the mobile device's screen and Singh et al (2010) create a low cost interactive electronic whiteboard by using a projector and Nintendo Wiimotes. Also, there are several WirelessHD protocols such as WHDI, WiDi, WirelessHD and Miracastto beam a display wirelessly from a small device to TV or projector.…”

A low-power structured light sensor for outdoor scene reconstruction and dominant material identification

“…The optics of these projectors are fundamentally different from larger projectors: many use laser light sources and do not suffer from focusing issues. Recent efforts in the fields of augmented reality, human-computer interaction and ubiquitous computing exploit the properties of these new projectors [8,24,6]. However, almost all this previous human-centered work is targeted at indoor scenes (such as offices).…”
