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

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

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)

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

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

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.

Costs Monetary Costs – Approximately $1750 which includes the following –Wheelchair –Sip/Blow sensor –Microprocessor –ROM & RAM –LED’s »Just to name a few

Costs continued… Sell Price: –Approximately double manufacturing cost: $ 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
