Timeline

Works done this semester Audio Debugging - We have found the resistance value, so audio

debugging needs the final testing on the actual device.

Switch/Timer - It is still in Design Phase

Development System - Need some more parts to be purchased or

received from the project partner to be assembled fully.

Development System @ Smitty’s

Problems Encountered Audio Debugging - We had some difficulty when we tried to

measure the resistance form the audio output of the VCR but it was resolved.

Switch/Timer - We thought were confident when building each

device separately but having to build a device that needs both function in one made us lost.

Development System - Device needed for building the development

system are not still received or purchased.

Projected Outcome Audio Debugging - We are hoping to try the found resistance value on

the actual device to see rather it works properly.

Development System - Receive or purchase the parts needed for full

assembly.

Switch/Timer - Currently we are thinking to use a micro-processor to

implement the functions required. If a suitable micro-process that can count exactly “one second”, we might be able to program that can show on the screen and get inputs from device.

Software - Database Paperwork problems at UPRC

Barbara expressed difficulties keeping up with all the paperwork she has to go through.

Had the idea to implement a database to help out with the paperwork, by doing everything online instead of by hand.

UPTV issues with PowerPoint, inconsistencies with flyers Barbara had to make paper flyers and UPTV

slides separately, this does not need to be the case with a database

Expressed difficulty using PowerPoint in general, had to manually change flyers every week.

Software - Database Solution to both problems: Utilize a database

A database holds information, like a file cabinet. Data in the form of text or specially formatted fields (think of labels) can be stored in the database and then retrieved and then displayed in any way you want it.

Using a database would eliminate PowerPoint all together. Now the database would be in control of displaying formatted flyers to the TV system. It would be able to do this automatically withoutthe need to manually change the slideshow or restart the system.

Able to update database from any computer connected to the UPRC network. No need to ever touch the actual computer the database is being run off of.

Software - Database How will this be accomplished?

Database software being used is called MySQL. It is quite popular and free to use, and the programming language being used in conjunction with it is also popular and easy to use.

Online programming language being used is called PHP. PHP is a very popular language to use online mainly because of it’s close ties to MySQL and it’s ability to display dynamic web pages. It allows web developers to use variables to display data that can change based upon the values of the variables. Think of a web page that can keep track of your name and greet you every time you visit.

Both PHP and MySQL need something called a web server to function. The web server being used is called Apache, and it is being used because again of it’s cost (free) and popularity.

Software - Database

A database is like a file cabinet, storing data and files

Software - Database A database is like a file cabinet, storing data and files

The database being designed for UPRC will be a bit morecomplex than a file cabinet, but generally that is how it works.

Instead of only paper being the input, there will be many inputs.

Flyers Events Food Menus Sign-up forms (events, trips, transportation, etc) Room Reservations Work Requests

Likewise, many outputs Online view, and forms to be put back into the database UPTV slideshow Calendar Printable Flyers

Software - Database UPRC database representation. An advanced file cabinet

Software - Database How to go about designing the database

When it all comes down to it, everything is just code Easier to split functions (inputs and outputs) into separate files,

rather than one large file. Easier still to split functions up into manageable chunks.

Two ways to accomplish communication from inputs to outputs

Many small individual files which represent the functions themselves in control of themselves, put together to form the system.

Hierarchal design - Slightly larger files, dependent on one larger “control” file which sends all variables and data to the other files.

Decided to use Hierarchal design due to it’s proficient use in computer engineering classes such as EE495d & EE437.

Software - Database Hierarchal design?

Think of a boss that splits up tasks into smaller portions for workers to perform. Notice number of connections to database.

Software - Database Actual screenshots of current database

Calendar See Flyers

Software - Database Expected progress

As Vince Ruppert is the only person working on this part of UPTV, he is planning on completing the basic form of the final database by the end of the semester. There will still be some fine-tuning to be performed at the beginning of next semester and the product may not be 100% ready to be used until the end of Spring 2007.

Next semester will focus more on working with the layout of the web pages that communicate with the database. This will allow the users of the database (the UPRC staff) a much more pleasant experience when working with the database system.

Timeline

Current Progress – ReACT & Sound System Connection ReACT

I am currently in the detailed design phase task. I have collected slides from past semester and

added some of my own personal touches. My next step would be to revise (add/eliminate)

ideas to make it presentable. Sound System Connection

In the last couple days, I have gone from specification development to detailed design phase tasks.

My next step, meet again at UPRC and actually take action. Once completed be able to get feedback from residents.

Current Progress - ReACT & Sound System Connection

Current Progress – ReACT

Current Progress – ReACT 10 Rules for Effective Communication

Do not speak from another room. Do not speak with your back toward the person with a hearing loss

(or their back toward you) Do not start speaking and walk away Do not start speaking and turn away from the person with a hearing

loss Do not speak in competition with something else (turn off the water,

turn down the radio, etc.) Do get the attention of the person with the hearing loss (do not start

speaking while s/he is reading or concentrating on the TV, etc.) Do try to speak face to face at all times Do try to remove obstructions while speaking (move your hand from

your face, the cigarette from your mouth, etc.) Do try to speak distinctly Do try to be patient

Current Progress - Sound System Connection

Current Progress - Sound System Connection 1. Saw what we had to work with

Removed the cover to the volume control in the Education Room.

Removed panels in the ceiling Ran into small problem!

Current Progress - Sound System Connection 2. Began to experiment

Turned on the main amplifier from the nursing station.

Undid some wires to see what would happen Removed the faceplate of the volume control in

the Great Room. Same set-up but one extra wire that we never figured

out what it did. Experimented with a stereo to see if our goal of

connecting the white speakers to the current system in the Education Room would work.

Finally, fiddled with the current system in the Education Room to see if the connection would accomplish our goal.

Current Progress - Sound System Connection

Current Progress - Sound System Connection 3. Came to conclusions

It is feasible to connect the white speakers to the current sound system in the Education Room.

If we want to use all 8 white speakers (Education Room & Great Room) we would need a separate wire going between the two rooms. Might need to involve extra people.

Plan For the Rest of the Semester – ReACT & Sound System Connection ReACT

Make plan for displaying ReACT principles on UPTV Distribute and display principles on UPTV Project will be completed by the end of the

semester Sound System Connection

Contact experts to get feedback Incorporate the unused speakers Make plan for connection of speakers

Current Progress – Dining Room I am currently in the Specification

Development phase of this projectLocated and reviewed noise measurement

data collected last semesterBrainstormed ideas for the new noise data

collection test plan In the process of creating new test plan

for noise data collection

Current Progress – Dining Room

Current Progress – Dining Room The noise measurement data collected in the dining room

last semester was located and reviewed The team used a docimeter to measure the noise levels,

however the use of a sound level meter would have been more appropriate

Docimeter designed for more high noise environments (e.g. factory)

Noise measurements collected were not very useful – descriptions of locations where noise levels weremeasured were not very accurate

Possibly due to use of docimeter and time constraints Average noise levels in the main dining room and Four

Seasons dining room was 70dBSPL

Current Progress – Dining Room Ideas for the new test plan for noise data

collection were brainstormed Detailed map will be drawn to aid in setting up

appropriate locations for measurements Use of a sound level meter to collect data

More appropriate than docimeter for our purposes Measurements will be taken in different

locations over several different days Would like to take measurements during both lunch

hours and dinner hours to see if there is a difference in the noise levels

Current Progress – Dining Room Began creating new test plan for noise data

collection Went to University Place to look at the dining

room Measurements of room dimensions for both the

Main dining room and Four Seasons dining room were taken

Created map for both dining rooms Need to return to University Place to look at Main

dining room again to finish map for that room

Plan For the Rest of the Semester – Dining Room Just began creating test plan so will

continue to develop this plan, which will be completed by the end of the semester

I will also be getting input regarding the design of my test plan from various sources

Implementation of my test plan will begin next semester

Current Progress – The Great Room

GREAT ROOM

Assistive Listening Devices

contact current users of ALD systems (i.e. churches, Elliot Hall)

contact manufacturer for specs. of potential ALDs

contact manufacturer re: how ALDs would work with current equipment

get samples of ALD and present to UPRC

consult residents/John re: ALDs ease of use

make cost analysis

buy equipment

monitor usage of ALDs

Rearranging Seating take measurements of the room

brainstorm ideas/rough designs

consult Barb/John

draw in each seat in a comprehensive drawing

arrange chairs for an event

get feedback from residents in the form of a survey

We are a little bit ahead of schedule on the ALD part of this because the issues of installation and how the ALD would work with our current system have already been addressed.


Assistive Listening Devices: Specification Development Phase The specification Development Phase was started last semester, and

three options were suggested for the future team to look into The Personal FM system was quickly dismissed because each

resident would have their own wireless mic, which meant that the speaker would have any number of mics on at one time

The infrared system and the FM system were both researched, but the infrared system was thrown out due to cost and needs of the residents confirmed by a survey

Of 26 residents surveyed, 18 think it is difficult to hear in the Education room

Only one resident had a hearing aid with a telecoil Additional notes from the survey: (1) the mic feeds back a lot, and has a

very tinny sound; (2) residents did not indicate trouble hearing during musical presentations; (3) staggering of chairs would be beneficial, as many residents were leaning out of their chairs to see (more later re: this)

Useful for majority of residents

Easily coordinated by staff

Current Progress – The Great Room Assistive Listening Devices: Specification Development

Phase Systems were narrowed down to three: the Listen Performance

package, the Personal PA value pack, and the Pro Wide Band FM system

The Listen Performance Package was used and recommended by Elliot Hall and Central Fellowship Church; in addition, the distributor Marilyn Electronics, hailed the Listen system as themost reliable and hands-free; however, the system is the most expensive

Originally had trouble getting in touch with the distributor, but Elliot Hall used a different distributor, Harrison Communications, which was much more helpful

• Assistive listening Devices: Conceptual Design Phase


Seating and Room Arrangement: Problem Identification Phase Rearranging the seating was just brought up this

semester as a possibility The team ran into a problem with accessibility issues

and fire codes, so not very much rearrangement of seating is possible

About 20 minutes of a lecture was observed when the survey was given out

Residents were leaning out of chairs trying to see The speaker did not really know how to use the equipment


Seating and Room Arrangement: Problem Specification phase – New goals were developed for this part of the project

directions for speakers about where to stand and how to minimize feedback

advising staff to stagger chairs slightly (not obstructing the aisles) to see if this will help residents see

Plan For the Rest of the Semester - The Great Room Find a way to get a sample ALD for

residents to try Develop a cost analysis for the ALDs

and decide on one recommendation move forward with Seating and Room

arrangement project by developing directions for staff/speaker
