Human Computer Interaction Assignment English Language Essay

Human Computer Interaction Assignment English Language Essay engineering science has had a big daze on society, as it has do many drastic improvements to the agency sprightliness in general has changed and improved so much. For instance, technology has improved us exponent of softwargon and hardw atomic number 18 in society. In numberition specialised ports bear helped lot with disabilities enabling diversity to take place.Describe the impact of HCI on society, the economy and culture, providing 5 (five) representatives of for each one topic.SocietyTouch secrecy phones, using phones is now easier because of the butt block outs insert/ discoverputGame controllers, game controls anyow you to play a game and connect with others by direct messages or attaching a microphone to it to talkRemote control, tout ensembleows you to remotely control something without being right next to the thing you indispensableness to controlHead up Display, would be good for drivers since they wont corroborate to ask a sort from the road to see how fast theyre goingEconomyText readers, to a fault jazzn as text to speechVoice input, example telling a lamp to switch off and it switches off apprehension input, wheel chair substance ab exploiters bequeath dupe the ability to control their wheel chair by right thinking about itMobile communication, ability to call or text anyone world wide trim back complexity of input, everything is simplistic and requires no more than 2-3 options of inputCultureGames, allow people to connect with each other allowing one another to have an open mind and talk to assorted people with different opinions and thoughtsDeskilling work, androids/robots bequeath replace the easy things humans do, e.g. at tesco and a hardly a(prenominal) other places you can officiate yourself and self-checkoutMobile pull intainment, youre now able to watch videos about different cultures with your mobileLaptops, ability to search the internet, act with ot hers, watch videosDomestic appliances, things identical microwaves diswashersTask 2 (P2)Considering that the HCI design principles create a big impact on a users experience of a hardw be and software product, formulate the Schneiderman (eight rules) and Nielsens ten usability heuristics principles. Remember to explain perception, behaviour models and information processing.SchneidermanStrive for consistency either it be the consistent same lay out or colours, or the identical terminology used in menus, prompts and help screens, if it is in a standardized situation it should all be the same or somewhat similar.Enable frequent users to use shortcuts A regular user of a twisting or a certain type of application should have the ability to have a shortcut to things they use the most this would speed up the work flow. produce informative feedback When a user is interacting with their device or application, they should receive feedback that gives them a clear representation and is lik ewise understandable.Design dialog to yield closure A users gets a good feeling when they know in that respect is a flow to what ever theyre doing, that everything is in a chain, one thing has to happen in show for another. For example, sending a message on an application such as whatsapp firstborn you need to add the contact, hence the message its self, and and thence by and by youve sent the message it shows a D letting you know its been delivered.Offer simple error handling If something goes wrong with a device, a simple type of taking into custody should pop up to help the user with the problem that occurred. If a certain app crashes it should ask the user if theyd like a error report to be sent.Permit easy reversal of actions In other spoken communication undo this is needed in a HCI because it would prevent any permanent mistakes.Support internal venue of control a user should receive some what a type of display letting the user know that something is actually happeni ng. Lets say a user attempts to open a app and the app is taking a few seconds to get ready and open up, the user would instinctually think the app didnt respond to his/her physical contact so he/she leave attempt to reopen the app multiple times until the app malfunctions.Reduce short-term memory load When a user is using a device they shouldnt be thinking about the amount of times theyll need to propel a button or what not, it should be a simple click of a button, and with menus it shouldnt require a button push to go up or down it should be a simple bun bar.Nielsens ten usability heuristics principlesVisibility of System Status The outline should have a certain type of way to let the user know what is happening and with a good time.Match between system and the documentary world The system should be able to speak the users language, with the correct words and the right concepts and with the right time, so it is communicating clearly with the userUser control and freedom Some times when youre using a device in a rush you race to open random applications and then you have the ability to at present abort the application, without having to go through the process of the extended conversation.Consistency and standards The system should always have persistence across the platform. shift prevention The better the design is the one with the better error recovery, but also prevents users from making the same errors twice.Recognition rather than recall The user shouldnt have to remember the information from dialogue to another, it should all be recognisable and visible to the user.Flexibility and efficiency of use The system should have accelerators, which are unseen to the regular user but they allow the expert user to do things and navigate instantaneous with more frequent actions.Aesthetic and minimalist design Dialogues shouldnt contain information that is not needed in that specific area, you should always make sure your system is efficiently composed. sw ear out users recognise, diagnose and recover from errors Error messages and error prompt boxes should explain the problem in plain language without code, and should also precisely advise whatever the problem may be and also give advice to the user on a solution.Help and documentation Although a system is better without documentation, it might be undeniable to provide the help and documentation, so that any such information should be easily searched for and found. It should also be focused on what the users caper is and list the steps to be carried out.Task 3 (P3)McCann Phones a small and up and coming young mobile phone producer has decided to develop a saucy mobile phone inter fount for its next series of mobile phones to replace its highly successful first range. The developers have come up with three possible interfaces and they need to decide which one to use. It has been decided to carry out an investigation on the alternating(a)s prior to production. You have the supp ort of the software engineers and production manager so prototypes will be made available to you. As you are the resident usability evaluator it is your task to carry out any necessary survey work and to come up with proposal.Here are the three possible interfacesThe convention qwerty keyboard as used in most computer systems.An alphabetical keyboard (a, b, c, d, e,,z)A keyboard based on frequency of type us (e, t, a, o, n, rz)Design the input and output of your mobile prototype. Choose one of the suggested interfaces and explain why.F unit of measurement 23 HCITemplate of phone design.jpgClicking either one of these buttons will open up a certain app/webpage, depending on the one you click, for instance if you click on the one with f will open up a Facebook app or webpage.Reason why Ive added this to my mobile prototype is because people now use these two to impart with each other, with the button input being there, itll allow you to get in contact faster and easier considering all youd have to do is click a button.Task 4 (P4)The knob in the move of this dry wash machine system controls the different fabric washing systems and the settings for rinse and spin. The control does not have a stop in either direction in other words it continues to go all the way round to the next cycle.Create input and output for this machine which would be best for adjusting the cycle correspond to the fabric, temperature, speed and timer. You could draw a picture to help you explain the reasons. Provide two new ideas that are not available in the industry.img_0193.jpgBelow is what my design would look like and I will be explaining the two things that Ive implemented into my design that havent been used in the industry.2. Touch screen, everything you input will be touch done via the new sleek touch screen design.Child absorb passcode, this will be programmed in a way that it will be child proof, for example if you want to lock your machine after it has started and keep ever y button locked, youll enter the child lock. It is designed in a way so that no matter what you push nothing will be happening but to deactivate the lock youll first have to enter the first 2 digits right, this will then enable you to see what youre inputting and then you enter the rest of your passlock to unlock the machine. GUnit 23 HCITask 4 Design 1.pngTask 5 (P5)Based on the case scenario before, explain how you would interrogation your system according to its functionality. Comment on the usefulness of such system and point out any drawbacks.Testing the system child lockTo test the system youll first have to enter a child lock pass lock and then attempt to push any of the touch screen buttons and see if anything happens, and nothing should happen if the system is decent made. This will be useful considering little children love to stand beside the washing machine when its spinning and tend to push buttons, but with the child lock they wont be able to push any buttons.The downside to this system is that the password is 4 digits long and to have half access to the system youll have to correctly enter the first 2 digits otherwise youd just be pushing the keys and nothing would be happening, so the drawback would be if you forgot the passcode you would have to end up calling the company to come and reset your password.Testing the touch screenTo test this youll have to push what you want, for example, cotton, with 50 degrees Celsius and then on high spin, if the system is working by rights it would input the material first and then the temperature and then lastly the amount of spins it will be doing. The touch screen with the options is useful because its simple to use and you can adjust it to the way you want it and wont have to clock the washing machine knob to the way you want it, you just have to input the things you want with a touch of a button.The big drawback to having a touch screen is that if it is dented or illogical it will be not be opera tional properly, it probably wont even be operating at all, so you wont be able to input anything.Task 6 (P6)Bionic mass was once the preserve of futuristic technology shows. However, those Tomorrows World days could soon be reality with a pair of glasses linked to a computer offering hope to thousands of visually afflicted people in Britain.Current technology that can give profoundly visually impaired people a form of sight through a retinal implant is expensive and invasive, so developing an affordable, non-invasive alternative would be a welcome improvement.And this is exactly what scientists at the University of Oxford are working on. The technology works by having a tiny video camera mounted on to a pair of glasses, which relays information to a small computer in the users pocket. The computer recognises objects or people and relays the information to the lenses via tiny LED luminances. (Light-emitting diode). flock would see a bright light within the lenses themselves to as sign an object. The brightness of the light would then indicate how close, or how far extraneous the object was and that may be enough for the wearer to navigate their way around. apply a computer to interpret the world on behalf of the wearer means we could use different coloured lights in the lenses to allow different types of information to be fed back to the wearer explains Dr. Stephen Hicks, research associate in the subdivision of Clinical Neurosciences at the University of Oxford.The advances in mobile phone and computer game technology, such as face recognition, tracking software and depth sensors enable the visually impaired to access a whole new host of possibilities. (Extract from Metro, September 19, 2001)Explain how you would design the device and document how you would consider the input, output, the quantitative measures and qualitative measures of potence of your product.This would be designed on a pair of glasses with a lens that is 5cm thick, it would need to be sort of thick to fit in a pair of small LCD screen into each of the lens.The input and out put would work in a way with different bright colours, for example if the area is clear of objects and people it would be a black light with a blue light highlighting the walls so that the user of the glasses doesnt bump into the walls, and if the user is near people it would be a black light with green light highlighting approximately where the object or person is so that the user doesnt bump into them.If its dark at night instead of the backgrounds being black they would be washcloth and objects, people and walls would be highlighted with purple.The glasses would also be implemented with a vibrator and a sound billhook to make beeping noises when someone gets close to an object within a close radius of 50 centre meters, and depending on how low/high the object is, it will make a beep vibrate, the user has the ability to switch one of these of. Each beep and vibrate will have a differen t convey for example if a object is really close to the person and they can walk over it, it would simple beep twice and vibrate twice, just in case they didnt hear the beep.CUsershijh0736Pictures48416_1 copy.jpgEar percentage attached to the glasses that goes into the users ear, it sends beeping signals depending on the diameter of how close they are to a object, they can get the settings changed from where they where given the product, just in case the beeping gets annoying or they want to change the frequency of the beeping.LCD screen projecting lights, black background, with green to represent a object. If the person that is vision impaired isnt impaired badly, then they can ask someone to change the settings of the screen so that the black background is taken away and it is just see through but it would still highlight objects as green.If the person that is vision impaired is badly impaired, no need to worry their is a ear piece that also helps, with beeping when coming in c lose contact to a object.Submission Date Week commencing, 22nd October 2012 in class harm to submit on time is a serious concern.
