- Good Human Computer Interfaces
- Voice Interfaces
- Use
- Blind People
- Allows them to navigate around the interface even though they cannot see it
- Blind People
- Advantages
- Large range of access as more people will be able to use it
- More efficient as instead of looking and searching for the application or software you can just say where you want to go
- Disadvantages
- Less Security = Can record someones voice and play it = access stuff they shouldn't = breaking in = taking advantage
- Unusable if person has cold as voice no longer sounds the same as before
- Use
- Touch Sensitive Screens
- Use
- Mcdonalds / Fast Food Resturant Self-Service
- People Order instead of going to the tills
- Mcdonalds / Fast Food Resturant Self-Service
- Advantages
- Frees Up Staff = Do other Jobs/Don't have to employ as many staff
- More efficient = you know what you want so won't take as long to find it whereas staff have to have you say it 1 at a time
- Disadvantages
- Wet Fingers = Screen doesn't work = Screen doesn't work = Delays in ordering process
- Screen can be easily broken = delays in ordering process as staff have to serve more people whilst they wait for the screen to be repaired
- Use
- Biometrics
- Disadvantages
- More expensive to put in place + keep up to date + maintain
- Wet Fingers = Damaged scanner = Doesn't work for the people after them
- Has a belief that it is dangerous + that information is not needed in a school = parents don't allow their kids to have it done + go to that school
- Uses
- School Login System
- Makes signing in and out quicker = longer lesson + teaching time
- School Login System
- Advantages
- Much more secure as can't/much harder to steal and use someones finger print especially if its in a school situation like my use
- Saves time in lesson = it will take a couple of seconds for each kid to login as they walk through the door whereas register takes couple of minutes to check each kid is here or not
- Disadvantages
- Retinal Scanning
- Advantages
- Much more secure = can't/ harder to steal and use someones retinal scan
- Quicker to login = only takes a couple of seconds to scan then its the next person whereas at reception they have to search your name and make sure its the right person
- Use
- Hospital / Doctors Sign in
- Quicker + more efficient way of signing in instead of queuing in reception
- Hospital / Doctors Sign in
- Disadvantages
- Technology is more expensive to buy, implement and maintain
- If scanner is broken no one can use it until it is fixed seriously delaying login
- Advantages
- Voice Interfaces
