First, the seven characteristics that mobile phones for the elderly should meet.
1, the screen and font are large and clear.
You can see clearly without reading glasses. Old people's eyesight will decline, and the big font and big screen can make mobile phones enjoy watching news, photos and videos.
2. Good sound quality and loud volume
Loud volume, don't worry about not hearing the bell, and you can't hear what the other party is saying during the call. Good sound quality can even let the elderly listen to music outside, and even dance square dance with loudspeakers to enrich cultural activities.
3, the operation is simple
No matter how many functions are inconvenient for the elderly, it means nothing, even a disaster. The fewer functions, the better. It is best to keep the most commonly used functions of the elderly. After the function is rich, we should also do a good job in the ease-of-use design of the operation, so that the elderly can operate at a glance and be simple and easy to use.
4, long standby
Less charging, more worry. The old man has a bad memory, so don't give him the second-hand smart phone he doesn't use. If there is no electricity at a critical moment, it may bring a lot of trouble and even accidents.
5, rich in functions
Wechat and QQ for daily social interaction; High-definition photo recording; Watch the news; Watch the video; Rich games such as mahjong and playing cards are essential. With WeChat and QQ, most elderly people have voice chat with their children every day and discuss with friends where to play. Watching TV health programs with video software has also become a new habit of the elderly. Through mobile game software, the elderly can play mahjong, hoe the ground and play chess with more people online without leaving home.
6, high performance
Fast reaction speed, no jamming. In fact, the elderly have less time to tolerate Caton's mobile phone than we do. Think in another direction and reduce the time for the elderly to wait for a response. In fact, it is actually helping the elderly live longer in disguise. At the same time, in the face of mobile phones with frequent performance problems, the elderly are more at a loss than the young.
7. Fashion appearance
In line with fashion, beautiful and generous. The so-called "old machines" that can be seen in the market often have red and green interfaces and heavy appearance, and old people are often embarrassed to take them out. Replace beautiful smart phones, so that the elderly can also "show off" in front of their friends with fashionable big phones.
Second, the common problems of the elderly using mobile phones
1, presbyopia cannot see the screen clearly.
People over 45 will gradually experience the physiological phenomenon of hyperopia (commonly known as presbyopia). Their eyeball lens will gradually harden and thicken, and the adjustment ability of eye muscles will also decrease, resulting in a decrease in zoom ability. The upper limit of the experience of presbyopia in the elderly is 300 degrees, that is, the sight distance from 33cm to 45cm. The mobile phone needs 1080P resolution to achieve the best visual effect, and the best screen size is a 5-inch screen.
2, hearing loss can not hear clearly
With the increase of age, people's tissues and organs will gradually age, and there will be problems in the auditory system, which will lead to hearing loss. Hearing problems will affect the communication between the elderly and society, and the deafness of the elderly is irreversible. A professor of otology in a well-known hospital in Beijing pointed out that hearing loss began in high-frequency sound areas.
3, the screen is small, the keyboard is big, it looks dull and the grade is low.
At present, the old man-machine on the market are all small screens and large keyboards, which are similar in appearance and very low-grade. Old people also hope to have a fashionable mobile phone to use.
4. Mobile phones can only make phone calls and send text messages.
It's a little high-end Mobile phones can take photos, but the photo effect is poor and unclear, which is far from the existing mainstream mobile phones. Old people want to watch the news, but it is impossible to share good things with friends on WeChat or QQ.
Third, it is not suitable for the elderly who use mobile phones for a long time
1, severe neurasthenia
Long-term use of mobile phones may cause insomnia, forgetfulness, dreaminess, dizziness, headache and irritability. , thus aggravating the condition.
2, cataract patients
Long-term use of electromagnetic waves emitted by mobile phones can increase the temperature and edema of eyeball lens and aggravate the condition of cataract patients.
3. Patients with heart disease
Experiments show that the electromagnetic wave of mobile phone can make the ECG display abnormal. People who use pacemakers should also be aware that mobile phones may have an impact on the work of pacemakers. If a heart monitor is installed, using a mobile phone may affect the monitoring results and lead to misdiagnosis.
4. Patients with hyperthyroidism and diabetes
Because hyperthyroidism and diabetes are endocrine disorders, electromagnetic waves emitted by mobile phones may lead to endocrine disorders, so such patients had better not use mobile phones.
5. Patients with epilepsy
The electromagnetic waves generated around the brain of mobile phone users are 4-6 times that of space electromagnetic waves, which can induce seizures.
