Energy, Energy, Energy

• Wireless Power Hotspot that Charges All of Your Devices
  • Develop the wireless AP to charge the mobile device in distance

RF can Sense

• Keystroke Recognition Using WiFi Signals
  • WiFi Signals from router to mobile device, is changed by human's key stroke
  • Detect the changing signal and get the pattern with machine learning

New security threats

• MoLe: Motion Leaks through Smartwatch Sensors
  • Using the IMU sensors in smart watch, detect the key stroke
  • Calculate the most appropriate word with Baysian model

Emerging sensing methods

• Human Sensing Using Visible Light Communication
  • Prepare several light sources on the top, and many light sensors on the floor to be grid shape
  • Each light source get the shadow map
  • Using the maps, analyze human's movement in realtime

Localization and RFID

• EchoTag: Accurate InfrastructureFree Indoor Location Tagging with Smartphones
  • Make a tag by writing some message on paper

MobiCom 2016

Novel Communication Modalities

• The DarkLight Rises: Visible Light Communication in the Dark
  • Communication using invisible light
• Near-Ultrasound Communication for TV's 2nd Screen Services
  • TV generates sound based on the information it is showing, which is not hearable by human or animal
  • The sound is received by smartphone; TV and smartphone communicate each other by this signal.

User and Object Tracking

• CAT: High-Precision Acoustic Motion Tracking
  • Prepare more than two speakers in distance
  • Speakers send various the sound signal that only machine can detect
  • Smartphone receives the signal and calculate the location itself
  • The location information is used instead of mouse for desktop, for instance
• Device-Free Gesture Tracking Using Acoustic Signals
  • The sound from smartphone front speaker is reflected an object
  • Two speaker embeded in smartphone detects the reflected sound
  • Smartphone can detect the object's location or moving
• Emotion Recognition Using Wireless Signals
  • A device sends a RF signal in distance to human body, especially to breast
  • Divide the reflected signal into heartbeat and respiratory signal
  • Using two signals, run machine-learning algorithm to figure out the emotion

All Things "Location"

• LiTell: Robust Indoor Localization Using Unmodified Light Fixtures
  • Using light "fingerprint", detect indoor location

Mobile Sensing and Optimizations

• RnB: Rate and Brightness Adaptation for Rate-Distortion-Energy Tradeoff in HTTP Adaptive Streaming over Mobile Devices
  • Find the most compressed video out of the videos which have different brightness factors(I'm not sure)
  • Send the video which is the smallest to save the battery

MobiSys 2015

Mobility, Gaming, and Performance

• GameOn: p2p Gaming On Public Transport
  • Provide the experience to play game with who is in the same transport.

Wearables

• LookUp: Enabling Pedestrian Safety Services via Shoe Sensing
  • Using shoe sensor, detect whether there is something dangerous in front of user and push the alarm to smartphone

Joint WWW-Mobisys session

• Visually Fingerprinting Humans without Face Recognition

MobiSys 2016

Smart Environments

• LiveLabs: Building In-Situ Mobile Sensing & Behavioural Experimentation TestBeds
  • Sence the users' action or grouping state
  • Provide some benefits(discount ticket, for instance) based on the data

Transit and Mapping

• Mobility Modeling and Prediction in Bike-Sharing Systems
  • Predict where/how many the bike station should exist by the several data
