Mute SOS

An app that enables the simplest police-calling and emergency signaling so that people with an inability to hear or speak alike can contact the police or signal for help in the quickest and simplest way possible.

/ What inspired me?

A few days ago I read a news story. A mom and her three children lost lives in a fire disaster. The mother had called the fire station 3 times. However, due to the loud on-site noise, the operator could not hear their specific location clearly. Thus, the prime time for a rescue was missed.


This prompted some questions in my mind: there will be a lot screaming and yelling on the disaster scene. What should we do to make sure that information was passed effectively? How could the hearing-impaired, or the able-bodied unable to talk because of the somke, phone the police or signal for help? Hence I decided to work out an embedded app that allows all mobile users to reach out for help during emergency situations in a more efficient and accurate way than existing systems did.

Time Line

  • 05:04 a.m. The mother called fire station 3 times.

  • 05:23 a.m. The fireman arrived but did not break into the room.

  • 05:12 a.m. The mother called her neighbor for help. 

  • 05:30 a.m. Her neighbor called back but no one answered.

  • 05:40 a.m. More fireman arrived, but still, they did not break into the room.

  • 05:53 a.m. Fireman got into the room, was told that no one is in there. 

  • 07:00 a.m. Four dead were found in the bedroom.

/ What is the possible scenario?

Can not phone the police

Hearing-impaired users

• Can not make phone calls in any situation.

Do not want to be noticed

• Do not know the specific location
• Have an accent
• Too tense to describe the situation
• Can not hear clearly in noisy environment

Do not want to be noticed

• Robbery, indecency crime on the buses
• Places like casino or brothel
• False imprisonment and kidnapping

Need to attract other’s attention

Can neither call or type

Need to notice everyone or seek for help

Hearing-impaired users

Have no time

• Being attcked at night
• Fire or earthquake

• Catch other’s attention and send signals

• When emergency happened, sometimes users have little time to call for help or send messages

Can only make phone calls

*Already solved. Users could use Siri or Google Assistant to make phone calles.

Probability of successful police-calling

Shanghai police's emergency hot line 110 received 13.97 million calls in 2016-an average of 38 thousand calls daily. It is a significant amount of work.

The police had handled 13.97 million cases, among which 65% of them were invalid.

About one fifth of calls are not urgent, and those phone calls compete with pressing calls for the resources and services available 

-- Yan. L. (2017, January 01). Shanghai police: people should reduce 110 calls. Society. Ecns.cn. Retrieved April 18, 2018, http://www.ecns.cn/2017/01-10/240880.shtml

Citizens in Shanghai could also send message to the police and seek for helpl. However, most of the message reports are invalid information.

/ What do the end user think?
/ Information integration
资源 30_4x.png

After interviewing 18 people who have experienced emergency, I synthesized the entire process of emergency handling, from the occurrence of emergency, to the solutions, to their subsequent reactions, and identified factors deterring users from contacting the police. First, users need to overcome daunting psychological challenges to go through the complex, cumbersome procedures of police calling. Second, in specific situations, they might fear of possible retaliation if found to be the caller. Therefore, an ideal app should be able to facilitate a quick, logic description of the cases by helping organizing their ideas while ensuring privacy throughout the process, namely, not producing suspicious sounds.

/ Mind map

I categorized the methods they use to seek help during emergency situations and explored deeper causes. At the end of the mind map I created, I analyzed whether they were able to use phones, the status when they use phones, as well as the duration of use. Then I proposed three ways to activate Mute SOS immediately: long-press the “SOS” button to directly send a message to the police, press the “SOS” button to enter the page for filling information, and press the power button quickly for 5 times to send a message asking for help.

/ Who is end user?

The hearing-impaired, or the able-bodied unable to talk for the time being who encounter the emergency.

/ My design proposal

It is my wish to provide an app that enables the simplest police-calling and emergency signaling so that people with an inability to hear or speak alike can contact the police or signal for help in the quickest and simplest way possible.
