Part 1. Task and fundamentals : What is synesthetic product design? -- Product development as the design for all senses -- Human-machine communication ; Functional design ; Product placement and brand identity ; The significance of multisensory environments -- Fundamentals of perception : The senses of distance: seeing and hearing ; Physical senses of proximity ; Chemical senses ; Perceptual objects ; Subjective or objective? ; Qualia ; Grouping ; Gestalt principles ; Foreground and background -- Part 2. Strategies of perception and design : Connection of modalities within the perceptual system : Overview ; Rules of connection ; Elementary connections -- Finding similarities: cross-modal analogies : Analogy relationships ; Temporal analogy ; Intersensory attributes ; Analogy of motion and kinetic design ; Spatial analogies and soundscapes ; Functional analogy ; Tactile design -- Recognizing familiar features: iconic connection : Associative connections ; Onomatopoeia ; Pictogram and auditory icon ; Associations to smell and taste ; The context -- Understanding the meaning: symbols and metaphors : Symbolic connections ; Color symbolism ; Synesthetic metaphors ; Symbolism in brand design ; Musical symbolism -- Exploring individual perception: genuine synesthesia : Hearing colors, seeing acoustic tones ; Smell, taste, and everything else ; Subjective color-form relations ; Movement of synesthetic images ; Visualization of meaning ; Why synesthesia?: Function and significance -- Consciously constructing: mathematical and physical connections : Algorithms and concepts ; Objective color-sound relations -- Part 3.
