Lift using projected coded light for finger tracking and device augmentationShang Ma
We present Lift, a visible light-enabled finger
tracking and object localization technique that allows users to
perform freestyle multi-touch gestures on any object’s surface in
an everyday environment. By projecting encoded visible patterns
onto an object’s surface (e.g. paper, display, or table), and
localizing the user’s fingers with light sensors, Lift offers users a
richer interactive space than the device’s existing interfaces.
Additionally, everyday objects can be augmented by attaching
sensor units onto their surface to accept multi-touch gesture
input. We also present two applications as proof of concept.
Finally, results from our experiments indicate that Lift can
localize ten fingers simultaneously with an average accuracy of
1.7 millimeter and an average refresh rate of 84 Hz with 31
milliseconds delay on WiFi and 23 milliseconds delay on serial
communication, making gesture recognition on non-

12. Mobile Devices using Hybrid Positioning
• Positioning Technologies need to be transparent to users.
• The device need to become positioning aware and switch between positioning
technologies seamlessly.
• Proper handling of transition and handover areas is crucial
• For example:
• the Application sets the QoS requirements
• The Filter select the most appropriate positioning technology: meet the requirements by using
the least power consumption
• Data Fusion could be carried out using
• Hard decisions and switching between technologies
• Particle Filter
• Kalman Filter
• In order to combine independent data streams, it is very important that each estimation
technologies provides at least
• the real-time variance (or any measure of uncertainty) of the generated location data
• Some form of Time Stamp

14. Positioning Content Layer
• Maps comprises of several layers of information, having different roles:
• For visualization and rendering
• Search
• Routing
• Navigation and guidance
• The Positioning Content Layer (PCL) comprises of information needed for running the
positioning algorithm.
• PCL are “invisible” to the user.
• In order to make the whole indoor solution scalable, secure, and sustainable, the PCL
need to be referred to one map
• This should also simply synchronization and data management

18. Two Modes of HAIP – Technical Principle
Network centric mode:
Mobile centric mode:
• A Tag or a Mobile Phone transmits
BLE packets at regular intervals
• Locator(s) transmit(s) BLE packets at
regular intervals by using a switched
antenna array
• Locator(s) receive(s) the packet by
using a switched antenna array and
provides measurements to a
centralized localization server
• A Mobile Phone receives the packet(s)
and calculates its own position

28. Pedestrian Dead Reckoning
TARGET: to evaluate the performance of a
Nokia made sensorbox for PDR
• Nokia sensor boxes were calibrated and
characterized against commercial
MicroStrain IMUs
• Plain PDR relies on step detection and
requires step length calibration for the
user
• But: in hybrid positioning case step length
calibration can be handled automatically
Nokia Research Center
28
Nokia Internal Use Only
29. Motivation
• Solutions for outdoor positioning do not directly
apply indoors, and other easily deployable
approaches are needed
MicroStrain 3DM-GX2
www.microstrain.com
• With development of MEMS technology and
sensors inertial navigation show some promises
• No infra required fill the gaps
• Through inertial navigation the distance and
heading of the user is tracked from a known initial
position and direction
• therefore inertial navigation alone will not suffice,
but complementary aids are needed
Nokia Research Center

29
30. Approach
• Complementary Kalman filter
tracks the
error states of 15 parameters: position, velocity,
attitude, gyro and accelerometer biases (all in
3 dimensions)
*)
• Map information can be taken into account
through particle filter
• Pros: No need for separate step calibration,
but it’s ready to go
• Cons: Computational costs

39. BLE Proximity Positioning
Concept description
• Applicable on BLE devices:
with BLE tags:
• Tags put on known positions and used as anchor nodes
• Only tag address + RSSI is used, data payload arbitrary
• Any BT or BLE device usable
• Tags used as anchor nodes; e.g. Place one in each room
• The appplication runs on Nokia N9 devices and it uses the BLE
chip already on board of the device to detect the HAIP BLE tags
• Different algoritms for positioning
• Tag with strongest RSSI (room environment)
• Interpolation for multiple tags (open space)

40. Beneficts
• The system uses standard Bluetooth 4.0 technology
• Tags
• time life 1-2 years, practically no maintenance needed
• Easy installation
• They can be hidden without altering the appearance of the indoor environment
• No cabling needed, not even power cable
• Effectively, their installation is as simple as install fire alarms
• NO system maintenance
• The positioning system does not need to be calibrated
• NO Finger Printing data and/or radio maps (as for WLAN positioning) needed
• Nokia Research has develop a simple tool allowing anyone to deploy and set
up its own BLE proximity positioning system.
• Part of this work is done in cooperation with NAVTEQ Research where also integration to
indoor maps is taken into account
