The flavor of food is not just limited to the sense of taste, but also it changes according to the perceived information from other perception such as the auditory, visual, tactile senses, or through individual experiences or cultural background, etc. We proposed "Gravitamine Spice", a system that focuses on the cross-modal interaction between our perception; mainly the weight of food we perceived when we carry the utensils. This system consists of a fork and a seasoning called the "OMOMI". User can change the weight of the food by sprinkling seasoning onto it. Through this sequence of actions, users can enjoy different dining experiences, which may change the taste of their food or the feeling towards the food when they are chewing it.

OverviewHaptoMIRAGE is a simultaneous multi-user autostereoscopic display for seamless interaction with mixed reality environments. This system can project 3D contents in mid-air and enable as many as three participants observe the same contents with a 150 degrees wide-angle view. The system can be used in several scenarios, such as superimposition of 3D content onto real objects, and multi-user collaborative drawing in the real world. Further, users can interact with the 3D content, such as rotating it and viewing it from different angles, allowing them to easily create and feel the mixed reality world via tangible objects with multi-modal sensations. Active-shuttered Real-Image AutostereoscopyAs shown in Figure 4, Active-shuttered Real-Image Autostereoscopy (ARIA) (Nii et al, 2012) technology comprises an LCD display, an active shutter, and a Fresnel lens. The Fresnel lens makes the real image from the LCD display, while the transparent LCD panel-based active shutter provides timedivided rays of light for the left and right eyes. The user's point of view (PoV) is calculated with a camera-based motion capture system and the projected 3D content transformed to his/her viewpoint. The proposed HaptoMIRAGE system (Ueda et al, 2013) comprises three ARIA units, each with 50 degrees autostereoscopic field of view, resulting in a total of 150 degrees, which enables three users to experience the contents from different viewpoints simultaneously.
