Recent research demonstrates the existence of a number of surprising associations (otherwise known as crossmodal correspondences) between seemingly non-related features in different sensory modalities, such as between basic tastes and colours. These correspondences have been incorporated into a dish called ‘The Four Tastes’ by chef Jozef Youssef. The dish is presented with four separate elements, each having a distinctive colour. Diners are instructed to match the colour to the appropriate taste (bitter, sweet, salty and sour). After establishing the association, the modernist chef, molecular mixologist, food designer or culinary artist can then either choose to design tasting experiences that align with these crossmodal correspondences or else play against them (to create incongruency and surprise). The former strategy typically leads to increased liking, possibly as a result of the diner being able to process the sensory information more fluently. The latter, by contrast, can elicit disconfirmed expectations, which can result in positive or negative experiences. While surprise is something that a growing number of diners are coming to expect when they visit a modernist restaurant, it tends to be a much harder approach to implement successfully in other contexts. Here, we present the literature on colour/taste correspondences, and discuss the implications of crossmodal (in)congruence in food design.
Abstract. Human Pacman is an interactive role-playing game that envisions to bring the computer gaming experience to a new level of emotional and sensory gratification by setting the real world as a playground. This is a physical fantasy game integrated with human-social and mobile-gaming that emphasizes on collaboration and competition between players. By setting the game in a wide outdoor area, natural human-physical movements have become an integral part of the game. Pacmen and Ghosts are now human players in the real world experiencing mixed reality visualization from the wearable computers on them. Virtual cookies and actual physical objects are incorporated to provide novel experiences of seamless transitions between real and virtual worlds and tangible human computer interface respectively. We believe Human Pacman is pioneering a new form of gaming that anchors on physicality, mobility, social interaction, and ubiquitous computing.
New developments in the design of high-speed electric trains are discussed, with particular reference to the induction motor drive system. A new high power three level converter-inverter system applying advanced insulated gate bipolar transistors (IGBTs) is described. Advanced control techniques lead to a unity power factor seen by the ac supply as well as minimising the line harmonics, power loss, motor torque ripple, and audible noise. By using advanced ac inverter drive systems the recently developed high speed train offers high level performance, efficiency, and passenger comfort.The described system is implemented in the latest "Bullet" or Shinkansen train sets operating in eastem Japan between Tokyo and Nagano, IntroducfionThe ac inverter drive system can be thought of as consisting of two major parts: the driving part that contains the ac to dc converter, dc to ac inverter, and the induction motors, as well as the control part that consists of the controller circuit and software. This ac drive system has become the most advantageous system for the powering and driving of electric trains. This is because it offers many beneficial features such as high performance, compacmess and lighter weight, easier maintenance due to contact-less circuits and brushless motors, lower cost, and high reliability. In this paper the an advanced high power ac converter-inverter drive system that has been developed at Mitsubishi Electric for the driving of trains will be discussed. Advanced techniques have been applied to the design and development of the four-quadrant ac to dc converter and dc to ac inverter systems of the induction motor drive. This includes the implementation of unity power factor control, multiinterlaced phase shift control, and three level synchronous PWM switching. Additionally, a low harmonic three level P W M control is applied to the inverter.These techniques produce lower harmonics in the traction motor supply, which leads to lower energy loss, torque ripple, and audible noise. In addition, the ac supply sees a unity power factor load, and the supply line harmonics are lowered. This ensures a good compatibility between the converter and the ac supply, as well as leading to reduce power losses, vibration, and noise in the main ac supply transformer. Hence, these control techniques lead to high train perfonnance in terms of efficiency and harmonic control, as well a marked increase in passenger comfort due to lower vibration and noise. In the following sections, details of the recent converter and inverter drive development will be given, Firstly the induction motor drive hardware system will be detailed. Then the next part of the paper will detail the converter topology and various Shoichi Kawamoto, Takeo Matsumoto, and Hideo Obi Mitsubishi Electric Amagasaki, Japan control aspects such as three level PWM switching, unity power factor control, and phase shift control. Finally the inverter system with three level topology and harmonic ripple control will be detailed. Experimental results will be shown t...
