Virtual Interpersonal Touch and Digital Chameleons

Abstract: We studied the characteristics of hand touch with a mechanical device that approximated a handshake, and we then examined the effect of handshake mimicry on assessment of a partner. Two participants interacted with a force-feedback joystick that recorded each of their hand movements individually. The two participants then greeted one another by feeling the recording of the other person’s movements via the force-feedback device. For each dyad, one of the participants actually received his or her own virtual handshake back under the guise that it was the other person’s virtual handshake. Results demonstrated three significant findings. First, for any given participant, a metric that took into account position, angle, speed, and acceleration of the hand movements correlated highly within individuals across two handshakes. Second, across participants, these metrics demonstrated specific differences by gender. Finally, there was an interaction between gender and mimicry, such that male participants liked people who mimicked their handshakes more than female participants did. We discuss the implications of these findings and relate them to theories of social interaction.

Methods and apparatus for accelerating secure session processing

Abstract: Methods and apparatus are provided for an entity such as a CPU to efficiently call a cryptography accelerator to perform cryptographic operations. A function call causes the cryptography accelerator to execute multiple cryptographic operations in a manner tailored for specific processing steps, such as steps during a handshake phase of a secured session. The techniques provide efficient use of hardware processing resources, data interfaces, and memory interfaces.

The handshake as interaction

Abstract: The Handshake is a social act wherein we have a combination of contact experience between two hands of different persons that communicates the degree of mutual physical resistance äs well äs the exchange of social identities and the beginning and ending of social activity. The Handshake has been discussed äs a form of nonverbal communication and has acquired such labels äs tie signs (Scheflen and Ashcraft 1976; Goffman 1971; Morris 1977); emblems (Harrison 1974); tactile modes (Leichty 1973); collapses, openers, and closures (Schiffrin 1974); tactile holds (Scheflen and Ashcraft 1976); metasignals (Scheflen 1972); access rituals (Goffman 1971; Schiffrin 1974); and greeting behavior (Scheflen 1972). No doubt the common reference point among these definitions is in the meaning of the Handshake äs a physical act. We can look to the following definition to set a basic reference point.

Method of audio-video synchronization

Abstract: A method for synchronization of an audio stream and a video stream comprising the steps of (A) determining a first presentation time stamp from the video stream and generating a first handshake signal when the video stream is ready to be transmitted, (B) repeating and dropping one or more audio frames of the audio stream in response to the first handshake signal and a plurality of first predetermined threshold values until a second presentation time stamp from the audio stream matches the first presentation time stamp and generating a second handshake signal when the audio stream is ready to be transmitted and (C) transmitting the video stream and the audio stream in response to the second handshake signal.

Clock synchronization through handshake signalling

Abstract: We present a method for synchronizing pausible clocks in GALS (Globally Asynchronous, Locally Synchronous) systems. In contrast to most conventional GALS schemes the method is not based on including in each ring oscillator a synchronizing element (such as for instance an arbiter) which on one side can pause the clock and on the other side offers a handshake interface. Instead, we propose a scheme in which each synchronous module has both an incoming and an outgoing clock signal, which have been obtained by opening the module's ring oscillator. Since these clock signals also behave as handshake signals, handshake circuits can be used to synchronize the clocks. We demonstrate the technique in the context of processors and memories. All the designs have been simulated and showed functionally correct.
