As autonomous entities, independent from the intentions of the individuals it is made of, consciously acting in the world. When looking for factual prove of the existence of such a proactive, instead of floral-like adaptive, intelligence, one can only start by assuming that this entity must produce some observable patterns. Patterns we can isolate and decode.\n\nThe search for urban crowd intelligence will be undertaken by approaching the crowd as a medium in which particles can be dissolved and from which meaning can be extracted by analysing the self-assembly of these particles into Crowd Crystals.\n\nThe Crowd Crystal are formed in response to, and are the result of, crowd agitation. A crystal is a book that tells us about the system that produced it. And no: putting them under your pillow will not cure you from your constipation.\n\nHere we present 2 crowd-crystal simulations as an aid to reflection to help prepare experiments with real crowds and real agents. One simulation is based on the study of trajectories, the other aims at understanding crowd-crystal semiotics." stringtraject="Crowd Crystal Simulation [trajectories]\n\nSTART: The crowd (the circles) are\ randomly assigned a position and a direction. The crystalline agents (the black rectangles)\ too are assigned a random position, they however only move when at least 3 crowd-members are\ within the boundaries of its proximity and it moves to follow.\n\nRUN: The behaviour of\ the crystalline agents can be altered by widening or narrowing the space it recognises the\ crowd. This is done with the CRYSTAL DEPTH slider. The CRYSTAL DEPTH button draws the\ current detection field for each crystalline agent.\n\nANALYSIS: By using the TRACE button\ the movement of the crystalline agents over time are shown. In combination with the ABS. MOVEMENT\ button traces can be compared with the original position of the agent. Use your Novalis-instinct \ to make sense of this and leave feedback when interesting patterns occur.\n\n" def stop(): r.destroy() r.quit() r=Tk() r.config(bg="limegreen") r.overrideredirect(1) t=Text(r,width=90,height=40, bg="grey", wrap=WORD) t.grid(column=0, row=0) t.insert(END,string1) t.insert(END,stringt) t.insert(END,string2) t.insert(END,stringt) t.insert(END,stringtraject) b=Button(r,text="close", command=stop) b.grid(column=0, row=1) r.mainloop() def start(): # def crowd for i in range(0,250): x=random.randint(0,70)*10 y=random.randint(0,45)*10 d1=random.choice(seq) d2=random.choice(seq) if d1==0 and d2==0: d2=random.choice(seq) crowd.append([x,y]) direction.append([d1,d2]) c.create_arc(x,y,x,y,start=0,extent=359, fill="white", style="chord") def atoms(): # def crystal for i in range(0,120): x=random.randint(1,70)*10 y=random.randint(1,45)*10 crystal.append([x,y]) c.create_rectangle([x,y,x+5,y+5], fill="black") copycrystal.append([x,y]) def drawcryst(): tekstt=string.join(tekst) leeg=Label(root,text=tekstt[-10:]) leeg.grid(row=2,columnspan=5) for x in range(len(crystal)): c.create_rectangle(crystal[x][0]-2,crystal[x][1]-2,crystal[x][0]+2,crystal[x][1]+2, fill="red") def abmove(): for i in range(len(crystal)): c.create_line(copycrystal[i][0],copycrystal[i][1],crystal[i][0],crystal[i][1], fill="lightblue") def walk(): c.delete("all") for x in range(len(crowd)): pedestrian=crowd[x] pedestrian[0]=pedestrian[0]+direction[x][0] pedestrian[1]=pedestrian[1]+direction[x][1] if pedestrian[0]>700:direction[x][0]=-1 if pedestrian[0]<0:direction[x][0]=1 if pedestrian[1]>450:direction[x][1]=-1 if pedestrian[1]<0:direction[x][1]=1 c.create_arc([pedestrian[0],pedestrian[1],pedestrian[0]+3,pedestrian[1]+3],start=0,extent=359, fill="white", style="chord") def atomwalk(): if tracerstatus[0]=="show": trace() if moveski[0]=="show": abmove() for i in range(len(crystal)): prox=[] x=crystal[i][0] y=crystal[i][1] ss=sl.get() # determine for each crystal the atoms in proximity for ii in range(len(crowd)): xx=crowd[ii][0] yy=crowd[ii][1] if x<(xx+ss) and x>(xx-ss): if yy<(y+ss) and yy>(y-ss): prox.append((xx,yy)) #when enough atoms in prox: move if len(prox)>2: if (x,y) not in tekst: tekst.append((x,y)) d1=d2=0 for ii in range(len(prox)): d1=d1+prox[ii][0] d2=d2+prox[ii][1] if x>(d1/len(prox)): if ([crystal[i][0]-5,crystal[i][1]]) not in crystal: crystal[i][0]=crystal[i][0]-5 elif x<(d1/len(prox)): if ([crystal[i][0]+5,crystal[i][1]]) not in crystal: crystal[i][0]=crystal[i][0]+5 elif x==(d1/len(prox)): pass if y>(d2/len(prox)): if ([crystal[i][0],crystal[i][1]-5]) not in crystal: crystal[i][1]=crystal[i][1]-5 elif y<(d2/len(prox)): if ([crystal[i][0],crystal[i][1]+5]) not in crystal: crystal[i][1]=crystal[i][1]+5 elif y==(d2/len(prox)): pass if crystalstatus[0]=="show": c.create_rectangle(x+ss,y-ss,x-ss,y+ss, outline="lightgrey") c.create_rectangle(x-2,y-2,x+2,y+2, fill="black") def honderd(): c.delete("all") del crowd[:]; del crystal[:]; del direction[:]; del tekst[:]; del copycrystal[:] start() atoms() while 1==1: doe() def doe(): walk() atomwalk() root.update() def trace(): i=0 if len(tekst)>1200: tekst[:]=tekst[(len(tekst)-1200):] while i", override) root.bind("", override1) root.mainloop()
