    • Home Computing Unplugged: Why, Where and When People Use Different Connected Devices at Home Fahim Kawsar A. J. Brush Bell Labs Microsoft Research
    • Research Objective Understanding Residential Network Activity What devices people use to engage with what kind of Internet Activities and why? How Location and Time influence the device use and why? When and how frequently households engage with what kind of activities? Can we find homophily across households based on their Internet activities? Can we predict households Internet activities?

    • Study Methodology Online Survey Semi-Structured Interview Internet Activity Log
    • Internet Activity Log What are the most popular internet activities in the home? Is there a temporal pattern?
    • Dataset : Project LeYLab In-Home Internet Activity Traces Living Lab for Fiber based Services in the City of Kortrijk, Belgium. ALU 7750 Service Router with Report and Analysis Manager (RAM) was used in the backbone. 86 Households 75 Applications 60 Days 9288000 Data Points
    • Web Communication Web Activity Types Online Gaming Web Browsing File Sharing Online Shopping Video Watching Home Working Semantically identical applications were grouped together into 8 distinct Activity Types and most popular 6activities were selected for subsequent study. This selection was based on a combination of accumulated network traffic, frequency, duration and temporal regularity Social Networking Application to Activity Mapping

Most of the bedroom computing (gaming and video) is done by teenagers and young adults.

    • The Transformation of Desktop PC
    • Activity First, Device Next
    • The Role of Applications
    • Less Contention, More Personal Space
    • Summary 1 2 3 We offered a reflection on how connected devices are used in home, and how their usage dynamics has evolved over the years based on a mixed method study on 86 Belgium homes. We offered a set of design implications for future home computing applications by uncovering some of the facts that drives users preference for selecting specific device. Our findings highlight the way home computing has truly become unplugged, leaving behind the few favoured places in the home where people used technology in the past to spread out throughout the home into new locations.
