ABSTRACT We present a 2-way selection method to select objects in a physical environment with a novel feedback and transfer of control mechanism. A modulated laser pointer signal sent from a handheld device triggers a photosen- sitive tag placed in the environment. The tag responds via a standard wireless channel directly to the handheld with information regarding an object it repre- sents. We describe a prototype implementation for a Motorola iDEN i95cl cell phone, discuss the interaction challenges and application possibilities for this physical world selection that extends a common handheld device. We also compare this solution to related attempts in the literature.

    ABSTRACT: Securing wireless channels necessitates authenticating communication partners. For spontaneous interaction, authentication must be efficient and intuitive. One approach to create interaction and authentication methods that scale to using hundreds of services throughout the day is to rely on personal, trusted, mobile devices to interact with the environment. Authenticating the resulting device-to-device interactions requires an out-of-band channel that is verifiable by the user. We present a protocol for creating such an out-of-band channel with visible laser light that is secure against man-in-the-middle attacks even when the laser transmission is not confidential. A prototype implementation shows that an appropriate laser channel can be constructed with simple off-the-shelf components

    ABSTRACT: Small, mobile devices or infrastructure devices without user interfaces, such as Bluetooth headsets, wireless LAN access points, or printers, often need to communicate securely over wireless networks. Active attacks can only be prevented by authenticating wireless communication, which is problematic when devices do not have any a priori information about each other. In this article, we describe three different authentication methods for device-to-device authentication based on sensor data from various physical out-of-band channels: shaking devices together, authentication based on spatial reference, and trans- mission via visible laser.

    ABSTRACT: We present a novel interface for human-robot interaction that enables a human to intuitively and unambiguously se- lect a 3D location in the world and communicate it to a mo- bile robot. The human points at a location of interest and illuminates it (“clicks it”) with an unaltered, off-the-shelf, green laser pointer. The robot detects the resulting laser spot with an omnidirectional, catadioptric camera with a narrow-band green filter. After detection, the robot moves its stereo pan/tilt camera to look at this location and esti- mates the location’s 3D position with respect to the robot’s frame of reference. Unlike previous approaches, this interface for gesture-based pointing requires no instrumentation of the environment, makes use of a non-instrumented everyday pointing device, has low spatial error out to 3 meters, is fully mobile, and is robust enough for use in real-world applications. We demonstrate that this human-robot interface enables a person to designate a wide variety of everyday objects placed throughout a room. In 99.4% of these tests, the robot successfully looked at the designated object and estimated its 3D position with low average error. We also show that this interface can support object acquisition by a mobile manipulator. For this application, the user selects an object to be picked up from the floor by “clicking” on it with the laser pointer interface. In 90% of these trials, the robot successfully moved to the designated object and picked it up off of the floor. ©ACM, 2008. This is the author's version of the work.
