• Intimate Interfaces in Action: Assessing the Usability and Subtlety of EMG-based Mottionless Gestures
  
• Costanza, et al.
  

Outline

• Introduction
  
  • Nature of mobile communications devices
    
    • Often personal and private, but takes place in public spaces
      
    • Contrast generated by private communication in public problematic for:
      
      • Confidentiality of person who communicates
        
      • People who are disrupted and forced to listen to stranger's private conversation
        
    • Mobile phone users generally play active role; can decide whether to:
      
      • Engage in phone conversation in public, or
        
      • Wait until they are in protected, isolated area
        
    • Bystanders have passive role
      
  • Nature of mobile communication
    
    • Often phatic, whose only function is to perform a social task, as opposed to conveying information
      
    • Personal communication through mobile devices is a largely minimal
      
      • Involves exchanges of little information
        
      • Real function is to provide
        
        • remote awareness
          
        • reassurance to oneself about possibility to connect to one's own social network
          
      • Design of interfaces and interaction techniques need to take into account above observations
        
  • Proposal: mobile interfaces that provide affordance for minimal interaction
    
    • Users should exchange simple signs of presence with remote partner or friend in an easy, natural, and inconspicuous manner
      
    • Mobile interfaces should offer users some simple, low-bandwidth, low-attentional operations that can be performed without disruption or embarrassment even in public or social context
      
  • Attentional demands have been observed before mobile technology
    
    • Main involvement
      
      • Absorbs the major part of an individual's attention and interest
        
      • vVsibly forming the principle current determinant of his actions
        
    • Side involvement
      
      • Activity that individual can carry on in abstracted fashion
        
      • Doesn't threaten or confuse simultaneous maintenance of main involvement
        
  • Previous work: motionless gestures for subtle input as step towards defining intimate interfaces
