M1.35 IAT 106 Other Modes of Thinking Beside Spatial Verbal, logical, mathematical, statistical… They can be distinguished in terms of their representational and reasoning system: –Verbal -> using linguistic symbols –Mathematical -> symbols or reasoning system (e.g., logic, algebra, calculus, set theory).
M1.36 IAT 106 Other Modes of Thinking Beside Spatial Verbal, logical, mathematical, statistical…
M1.37 IAT 106 A curve traced by a point that moves so that its distance from a given point is constant. vs. X 2 + y 2 = r 2. Mathematics language Verbal language Spatial language Other Modes of Thinking Beside Spatial
M1.38 IAT 106 Spatial thinking as a universal mode of thinking Accessible to everyone to different degrees in different contexts As a means of problem solving Three important elements of spatial thinking: concepts of space tools of representation processes of reasoning
M1.39 IAT 106 Spatial thinking entails knowing about Space: –relationships among units of measurement, different ways of calculating distance, the basis of coordinate systems, the nature of spaces –structuring problems, exploring solution alternatives, finding answers, expressing solutions. –Objects and Relationships Objects and … Assemblies: collections of objects and relationships Representation: –relationships among views (plan vs elev), projections (mercator vs equal area) –describe, explain, and communicate the structure, operation, and function of those objects and their relationships Reasoning –Answer questions about the operations of assemblies.
M1.40 IAT 106 Functions of Spatial Thinking Spatial thinking serves three purposes: 1.Describing –capturing, preserving, and conveying the properties of and relations among objects 2.Analysing –understanding the structure and behaviour of objects 3.Inferring intent –generating answers to questions about the design and function of objects
M1.41 IAT 106 IAT 106 Spatial Thinking and Communicating Fall 2012 Part II: Objects, Space and Operations
M1.42 IAT 106 Design a bridge For pedestrians Across a canyon Joining narrow paths on either side Paths are 10m above the river 20m N
M1.43 IAT 106 How did you work? What words did you use? What drawings did you make? What are the parts of your bridge? What measurements did you use? How many options did you make? How did your bridge change as you worked?
M1.44 IAT 106 The elements of spatial thinking : –Objects structure the domain –Space relates objects –Operations change and move objects and space
M1.45 IAT — Objects Objects are things we work with. For each domain there are different kinds of objects: –Bridges: pier, span, truss, arch, stay,… –Biology: gene, cell, protein, biota,… –Sociology: neighborhood, stereotype, organization,… –Astronomy: star, planet, gravity,… –Business: invoice, statement, organization, staff,… Objects have names. Objects relate to other objects.
M1.46 IAT — Space Allows us to capture the fundamental spatial properties of objects –One common concept of space is based on dimensionality and uses a dimensional system –By limiting ourselves to objects in three- space for the moment, we can think about objects as instances of a point, a line, an planar "area", or a "volume"
M1.47 IAT — Space Derive a series of spatial concepts from the location properties of sets of objects. We can specify distance, angle, and direction (relative to a given frame of reference), sequence and order, connection and linkage. We can understand the structural properties of sets of objects in terms of boundaries, density, dispersion, shape, pattern, region, volume…
M1.48 IAT — Operations Operations allow us to change and move objects in a space –transform (e.g., translate, rotate, scale, shear) sets of objects within the space –change the spatial scale at which we operate (by zooming in or out) –change the units of dimensions (yd m) –change the dimensionality of the space (collapsing from three to two dimensions-i.e. projections)
M1.49 IAT 106 Summarizing The Process of Spatial Thinking Define your basic objects (primitives) Define space: measures, concepts,… Develop operations based on spatial concepts to change and move space and objects Let’s apply the process to a Gimbal example
M1.50 IAT 106 Gimbal Example Objects: Pivot, Ring, Base, Support –Pivot: a support that enables an object attached to rotate about an axis –Ring: A circular structure that is supported by one or two pivots to either another ring or to the base. Space: –Inner rings are smaller than the outer ring supporting them. –Rotations occur about axes in space. –The base sits on the XY plane. –Each object has a local coordinate system. Operations change and move space and objects –If the outer ring rotates about X-axis, the inner ring rotates with it; and if the inner ring rotates about its Y-axis, the object on the inner ring can be rotated about X and Y axes simultaneously. Two-Gimbal Mechanism
M1.51 IAT 106 Another Example GUITAR MAKING
M1.52 IAT 106 Creating a virtual guitar in SecondLife: Suzanne Vega’s Guitar by Robbie Dingo (3:05)
M1.53 IAT 106 Building a real Yamaha guitar (3:02)
M1.54 IAT 106 Discussion How does the video clip of the virtual guitar express the objects and their relationships in virtual environment? How does Yamaha’s guitar (real) compare to Susan Vega’s guitar (virtual): differences and similarities in concepts, process, techniques, operations? How is the ‘space’ defined in both examples?
M1.55 IAT 106 Visualization of a Guitar and its Parts Objects, Language, Concepts, Operations? Spatial Context: Life, Physical, Intellectual?
M1.56 IAT 106 Space? Space: both abstract structure and tool for relating objects Space as an abstract term (see )http://en.wikipedia.org/wiki/Space Space relates objects
M1.57 IAT 106 Space? Space relates objects
M1.58 IAT 106 Space in different contexts Mathematics: –An abstract conceptual framework within which we compare and quantify the distance between objects, their sizes, their shapes, and their speeds. Physics: –a set of dimensions in which objects are separated and located, have size and shape, and through which they can move. –the standard space interval is called a meter: the distance traveled by light in a vacuum in about 1/ second. Architecture: –A volume defined by objects; when associated with a function, becomes a "place".
M1.59 IAT 106 Properties of Space …compare and quantify the distance between objects, their sizes, their shapes, and their speeds number of dimensions for a space can be zero (a point), one (a line), two (a plane), more than three, finite or infinite… In our course, we study: –2D and 3D spaces, and sometimes with temporal (time) dimensions Space and objects as reference frames: contains, borders, divides
M1.60 IAT 106 Representation of Space Cartesian coordinate system: –Defined by X, Y, and Z axes, –the position of any point in three-dimensional space is given by means of three coordinates: x, y, z If any two axes are taken, they form 2D space, or a plane
M1.61 IAT 106 Representation of Space Cylindrical coordinate system: –Defined by polar and longitudinal axes, –the position of any point in three-dimensional space is given by means of three coordinates: r or ρ – radial distance Φ or φ – angular coordinate z – height Used in engineering analysis and in local navigation.
M1.62 IAT 106 Representation of Space Spherical coordinate system: –Defined by zenith and reference directions, –the position of any point in three-dimensional space is given by means of three coordinates: r or ρ – radial distance θ – polar angle Φ or φ – azimuth angle Used in celestial navigation, mathematics and physics.
M1.63 IAT 106 Objects in Space Location: –Absolute position in a coordinate system –Relative position with respect to another object existing in the same space –Tentative position, near, on top, south-west, behind. Distance: –To origin (of the base coordinate system) –To other object: in terms of coordinate system units, e.g. 100 meter, three block, four flours up Size: –Measured by coordinate system units –Measured by comparing another object, e.g. 1.5x bigger Shape (geometry): primitive (square, circle, triangle…) or complex (curvilinear, composite, nurbs …) Direction and orientation
M1.64 IAT 106 General Operations: move and rotate move and rotate, attach, detach, carve, cut… Move Rotate
M1.65 IAT 106 General Operations: attach and detach Attach Detach
M1.66 IAT 106 General Operations: cut and carve Cut Carve
M1.67 IAT 106 Discussion Did you see any other operations in: -the guitar making videos? -The gimbal? Look for Objects, Space and Operations.
M1.68 IAT 106 Understanding Complex Objects Objects made up of other objects: Assemblies
M1.69 IAT 106 Composing vs. Decomposing Problem-solving strategy: Divide-and-conquer strategy –Divide object into less complex sub-objects –Study relationship between them –Define the assembly rules –Use representations!
M1.70 IAT 106 Art and Engineering Spatial thinking crosses disciplines Objects … spatial relationships … assemblies…motion… Theo Jansen--engineering blends into art: Let’s decompose it … look at a “simple” sub-assembly of a single (wooden) Theo Jansen Linkage: A more pure (Kinetic) art eg:
