Background

• Imagine opening the door with a wink
• Imagine turning on the light with a simple blink
• Finally, Imagine controlling an object by merely
  looking at it.
• Imagine the SmartThink Remote System

3
Introduction

• SmartThink Remote System is primarily designed
  for people with disabilities that inhibit them
  from performing complex tasks, such as, opening a
  door, turning on a television set, or turning on
  a light.

Conceptual Design

• Given a room with various objects, depending on
  the direction the user is facing and the line of
  sight, objects can be activated.  
• SmartThink Remote System will use a sensor array
  attached to a target CPU which analyzes data in
  and translates the data into sensible output
  (i.e. which object, and activate the various
  states of that object).

Description of working system

• Boot code brings up FPGA and µController unit
• Transmitter begins transmitting
• FPGA has state machine which checks for a
  sip/puff interrupt and generates an interrupt of
  its own to the µController

6
Working System continued

• For optimal goal On head movement, helmet
  heading is sent as an interrupt to the
  µController and servo position is calculated
  based on this heading
• If transmitter holds line-of-sight with receiver
  (shown by visual LED), interrupt will transmit
  signal to activate selected object

Infrared Transmitter/Detector

• Transmitter sends out variable frequencies
• Receiver responds based on state and frequency
• Backup Can purchase IR system for minimal cost
  (50 - 100)

11
Why not RF?

• RF requires more error checking algorithms
• Superimposing signals generating unwanted noise
• IR is well used and products/support is easily
  accessible
• Strong interference in RF frequencies

12
Risks

• Working with wireless technology
• Networking with Radio Frequency (RF)
• Picking the correct components and getting in on
  time to build the motherboard
• Completion Time is it feasible

13
Contingency Plan

• We are aiming to achieve our maximum goal, but in
  case it does not work out, we plan to implement
  our target goal.
• Our target goal is to activate an object in the
  line of sight, and our maximum is to add the
  servos to control the transmitter.

14
Costs

• Monetary Costs
• Approximately 1750 which includes the
  following
• Wheelchair
• Sip/Blow sensor
• Microprocessor
• ROM RAM
• LEDs
• Just to name a few

15
Costs continued

• Sell Price
• Approximately double manufacturing cost 3000.00
• Labor/Man-hours
• As much as it takes to get the project to
  completion
• We are planning to spend about 10 hours per week
  as a group, plus additional individual times
  outside the group
