A lesson in usability from an octengenarian.

If you want to learn about usability then spend some time teaching an elderly person to use a piece of modern technology.

Yesterday I got a phone call from an elderly relative who had bought a new TV and was having difficulty tuning in the channels. It quickly became apparent that I wasn't going to solve this over the phone so I hopped into my car and went around to her house.

"Everything worked yesterday" she told me. "The man who installed the TV tuned in all the channels and showed me how to use it but I accidentally pressed the wrong button this morning and now I can only get channel 1"

The TV was a brand new Philips LCD and a few minutes playing with it convinced me that there was nothing wrong. The installer had programmed in 15 channels including all the channels this lady wanted to watch.

"It's all working now", I said. "You must have gotten stuck in a menu somewhere. This is how you get back out of any menu".

"No No" she insisted. " I pressed the wrong channel and now it is stuck. I cannot get the other stations".

Ah, I thought. "Perhaps it would help if I wrote down which numbers correspond to which stations." I spent a few minutes going through all the stations writing down the channel names opposite the numbers. She didn't seem overly happy with the list. "It's all very confusing" she said. "If only I hadn't pressed the wrong button it would be OK"

"Don't worry" I confidently predicted "I will show you how to change channels and how to get back out of any menus you press by accident".

I sat down with her and showed her how to enter the number of any channel. She was clearly unhappy with the procedure. When I handed her the remote to try for herself she stabbed at the buttons, sometimes getting the right digit more often getting no number or getting multiple digits. "This is very confusing" she said again.

The Philips remote didn't help. The number buttons were small rubber keys with the numbers written in squinty text above them. Even I had to strain to make them out and this lady hadn't a hope.

"Ok, Ok" I said." Here is an easier way". In my experiments I had noticed a menu mode for changing channel. Pressing a button in the middle of the remote brings up a menu that fills the screen with 15 boxes. You then use an annular ring like a joypad to navigate to the channel you want and press OK. Perfect. I couldn't think of an easier way to pick a channel myself.

"Pressing that button and you get a menu" I explained. "Do you see those 15 big boxes on the screen? Each of those is a channel. Can you see the channel numbers"

"No" she said as she stared at the unfamiliar pattern on the screen " Let me get my glasses".

Eventually I managed to explain to her that one of the boxes was highlighted and that would be the channel that came up when she pressed OK. "All you have to do is navigate to the box you want using the arrow buttons around the ring."

To my gamer trained instincts navigating a menu using a joypad is second nature but this octogenarian had never used a gamepad in her life.

"It's all very confusing" she pleaded again. "The man set it up yesterday but I pressed the wrong button and now I can't use it"

"To hell with that" I thought. I'll show her how to use the channel up and channel down buttons. There are only 15 channels after all so it won't take her too long to go through them.

Unfortunately instead of discrete channel up and down buttons the remote had a second annular ring outside the previous one with channel + and channel - on the right and left sides of it. This lady's arthritic thumbs struggled to press the narrow annular ring without pressing something else at the same time. As often as not she would advance two channels or none at all.

We had a minor breakthrough when she realised that she found it easier to press the channel down button than channel up. She managed to switch down through all of the channels with only a few mis-hits until she got to channel 1. Then she pressed again and got to channel 15.

"How did I go from channel 1 to channel 15" she asked perplexed.

"The numbers loop around in a circle" I tried to explain.

She wasn't buying it. She looked at me and once more said "It's all very confusing. It worked yesterday after the man installed it but I pressed the wrong channel and now I can't get the programme I want".

When I tried to explain to her that there was nothing wrong with the setup of the telly it was as if I was talking a different language. She was sticking to her story that it worked yesterday after it had been installed but some button she pressed had broken it and now she wasn't able to change channels. This lady may be in her eighties but mentally she is all there so I was confused. Could it be possible that there is a magical mode that makes it easy to use for the elderly? I searched for one and couldn't find it. Maye she is just too proud to admit that she cannot use the remote but to be honest it is a usability nightmare. The buttons are too small, the text is not clear enough and the timings are too unforgiving for someone whose dexterity is not what it used to be.

I have abandoned my attempt at teaching her to use the Philips remote. I am now on the lookout for an alternative remote with big clear buttons but that won't necessarily solve the unforgiving timings. I also need to be careful not to hurt this lady's feelings.

For anyone who is interested you can download a copy of the manual for this TV here: Philips 3000 Series manual. There is a good picture of the offending remote on page 8.

There's definitely a lesson here, but usability isn't it. The lesson here is on willful ignorance. While as a CS rep you're right in doing what you can not to offend her, the fact is that she doesn't know and more importantly from how you describe it, doesn't *want* to know. She's clearly happier blaming it on something breaking in order to at least partially shift blame away from her own inadequacies in dealing with new technology.

Hi JT you are very harsh and remember that I am only guessing at this ladies motivation.

I have other elderly relatives and I am often reminded of how much of the world becomes inaccessible to the aging population due to bad interface design. Even products that are designed specifically for the elderly often have chronically bad usability.

I do agree with you though that we can be our own worst enemies in not admitting to a problem and seeking realistic solutions. It would certainly have made my job easier if this lady had said to me: "I cannot use this remote control because the buttons are too small".

MBP, if you can get it through Amazon (maybe UK Amazon?) this is what you want: Large 6-button remote

Actually this one might be even better, because the previously linked remote not only has uni-color buttons but the Volume & Channel buttons are all identically sized triangles, whereas this remote has a Green On/Off button, Blue Channel up/down buttons, and Orange volume up/down buttons.

Thanks Capn John. They both look like a big improvement. I will check UK Amazon because there may be compatibility issues with the US version in Europe.

My own mother - who is close to 80 - resists me teaching her anything to do with remote controls, her mobile or laptop. I always get blamed that I don't explain myself properly but I feel it's more that she rather not know.

Gosh DM I am impressed that she uses a mobile and a laptop. My own mother (88 last week) is a technophobe and panics when confronted with any technology developed after about 1960.

This has become a real handicap as she gets older because she cannot use many conveniences that would improve her quality of life. Never mind computers and the internet. My mum will not use a microwave oven or even the stair lift we installed in her house.

I should explain by the way that my mother was not the lady mentioned in the main article. If it was my mum I would have known better even before we started.

Ah but there's owning something and using it & owning something and never turning it on. The latter applies and so they may just as well be back in the shop.

Portal 2 two screen coop on one PC.

I mentioned before that I intended to try Portal 2 in "unofficial split screen co-op mode. Well split screen on a small computer monitor is a recipe for a headache especially when the game defies gravity as much as portal. However a minor bit of extra fiddling allowed us to drive two seperate screens from one PC. The Steam forums describes a complicated method of doing this that I couldn't get working so this simpler method which worked for me might be of use to someone. 1. First I followed the instructions in this post to get split screen multi-player working: http://forums.steampowered.com/forums/showthread.php?t=1847904 A minor issue not mentioned is that you need to enable the console from the keyboard/mouse options menu I am using keyboard and one wired Xbox360 controller as suggested. Getting the controller to switch to channel 2 was tricky at first but as Chameleon8 mentions plugging it out and in again during loading works. The trick for me was to do the plug / p

Android Tip 3: Sharing a Folder between multiple users of an Android device

Android has allowed multiple user logins for quite a while now. This is can be very useful for tablets which are shared by family members. Normally Android erects strict Chinese walls between users preventing them from using each others apps and viewing each others files. This is a useful security feature and ensures your kids don't mess up your work spreadsheets when screwing around on the tablet and should also prevent them from buying €1,000 worth of Clash of Candy coins on your account. Sometimes however you really do want to share stuff with other users and this can prove surprisingly difficult. For example on a recent holiday I realised that I wanted to share a folder full of travel documents with my wife. Here are some ways to achieve this. 1. If you have guaranteed internet access  then you can create a shared folder on either Dropbox or Google drive. Either of these has the great advantage of being able to access the files on any device and the great disadvantage of bein

Lotro: The Forgotten Treasury

Throg joined a Kinship group for the Forgotten Treasury instance last night. It was an enjoyable change from the solo questing that the now level 55 dwarf champion has been mostly doing so far in Moria. Some members of the group had tried and failed to clear the Treasury before so we knew it would be challenging but we were lucky enough to have a well balanced group with Guardian, Minstrel, Lore Master, Hunter, Burglar and Champion (Throg). Throg (level 55) and the minstrel (53) were both below the 56ish level of the instance but the others were all higher so it more or less balanced out. [SPOILERs ahead] It is a well designed enjoyable instance set in a circular chamber with balcony around. As you enter, a boss absconds to a locked side chamber with his treasure leaving the fellowship to clear trash ringed around the balcony. Once the trash are cleared you have access to a puzzle which must be solved in order to open the locked door. Clearing the (including six mini bosses) also
