Telephone design for elderly people

Designing for the elderly could be considered as a hard task. Designers are usually not elderly and knowing how a product would be perceived could be considered a not so easy task. But the results of such a task could be highly rewarding as they directly impact on somebody’s life quality. Even more, usually designing for the elderly means designing for everyone. I show here some products designed keeping in mind the needs of the elderly.

Telephones are always a problem

Elderly people seem to be perfect victims for most home telephones and cellphones. They are difficult to use and they offer a lot of functions that many don’t understand how to find. But telephones are devices with a lot of importance to people, specially during emergencies.

Some companies have been designing telephones for the elderly, for example Doro. Big buttons and limited functions make the following phone a hit for those looking for simplicity. I find the possibility of writing the names on the same phone a great improvement for the older ones.

Digital menus

Navigating through menus on a tiny screen is a problem for a lot of people. Many get lost and don’t understand how to select, scroll or go back to the beginning. Interaction designers at Emporia, like at Doro, have been having this in mind and add a memory help notebook directly on the phone. Note that the notebook is all the time facing the user (and not in the back of the headset like in many home phones).

Functionality over style?

Designs for the elderly tend to be ugly: huge buttons, huge letters on a huge screen and terrible colors. But designing for the elderly is designing for all and if the designer is able to produce something appealing to everybody the product could be probably sold to a larger number of people.

The Deutsche Telekom released a home telephone that was initially thought to target the elderly. Not surprisingly a lot of young families are buying the phone. It has big numbers but they still look nice, it has fast dialing buttons and a paper notebook on the charging base.

Again, less digital menus

Something that people are requesting is to have more physical buttons. The Deutsche Telekom placed the answering machine controls on the charging station to make the listening of new messages easier.

That need for adding features

This telephone is including a flashlight and a radio, each function with its own button. Design research might have been revealed that those are important features for elderly people. But they also seem to be there just because it was possible to add something else. A dedicated button for a radio, do we really need that on a cell phone? Is that going to improve the user experience?

Ways to fix a design

Discovering that a product is not working as expected when it is already at the streets is not a pleasant feeling. Fixing a product design it is neither easy nor always possible. In this article I show you two typical examples of design fix that you should try to avoid.

First Case

Traveling to the Bavarian alps on a beautiful, high-tech train, I was doing something that the designers of it didn’t do: observing how people use doors and in particular how they would interact with their design. I was lucky enough to be sitting in front of the toilet’s door, enjoying the possibility to look at the passengers trying to deal with the door.

The design: the door had a door handle, a yellow button and a huge sticker indicating that people are not supposed to use the door handle to open the door; instead they should press the button.

What happened here? After many passenger breaking the "automatic" doors, designers decided to add an sticker to their design to try to fix it. Did it work? Obviously not:

Second Case

In Mar del Plata, one of the biggest cities in Argentina, people have been paying bus tickets with cash using machines installed on the buses. This system has recently been changed by another one that uses magnetic cards. These cards have to be loaded with electronic money at city kiosks; once on the bus passengers use the cards to paid for their trip.

The problem with the new design: people that were used to pay using cash were trying to introduce coins and bills inside the magnetic card reader. Probably, hundreds of readers got wroken and had to be replaced.

"Do not introduce coins"

The solution: designers (or maybe the people in charge of the system) tried to fix the poorly designed system with a sticker saying "DO NOT INTRODUCE COINS". Did it work? Probably not well. 

Why this is happening and what could have been done?

These two products, the high tech door and the card reader, were probably designed without taking into account many parts of the system. Observing a few people interacting with the train door would have been enough to notice that people would try to open the door using the door handle if there is one (and not a button). The same applies to the card reader, designers probably never got on a bus and observed people using the old ticket machines.

Specially hardware design flaws are difficult and very expensive to solve. In most cases a sticker would probably not solve the problem and would make the whole user experience even more confusing. 

A user centered design process should have prevented these design failures: doing field research, talking with people and observing what they need and how they behave in their environment.

Is this the Windowszation of the iPhone?

Apple recently announced the release of the new iPhone OS 3.0. Yes, it’s great and it comes with many new features we have been waiting for. One of those is worrying me a little bit: Push Notification.

Push Notification Logo

The Apple Push Notification service provides a way of alerting about new information, even when the user is not running the application. Alerts come in three flavors: it could be a numbered badge to be displayed on the application’s icon, it could also be a sound or it could be a text alert.

Looking at the feature from the user experience point of view, in my opinion, the numbered badges are great, sound alerts are just "OK" but text alerts are wrong. Text alerts will be highly distracting and might remind to disturbing message alerts found on Windows systems, like this one:

Just an example of alerts on Windows

Alerts are a great opportunity for developers and companies, specially for the ones developing IM services or critical applications that need users’ attention. On the other hand, I can imagine that a lot of these people could be tempted to abuse of the feature; ESPN, for example, announced that they would be sending 50 million notifications each month.

Apple has been creating fantastic user interfaces and I can not believe they didn’t think about the implications of allowing this kind of disturbing messages on a device like the iPhone. We have to wait a few months to see how text Push Notifications will be implemented, maybe not allowing them by default could help.
