Modal verbs terminology In the present document “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are

14、to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The success of alert messages with the purpose of warning the public a

15、nd individuals about potential hazards and disasters is dependent on the ability of the message recipients to: (i) understand that an alert message has been received; and (ii) to understand the contents of the alert message in order to draw the correct conclusions. Both these abilities may be restri

16、cted by specific sensory or cognitive requirements of individual users. Individuals with sensory impairments may not become aware of a published warning message unless the message is delivered in a modality which they can receive and interpret. For a warning message to be understood by its recipient

17、s it is essential that it is presented in a way that users can interpret correctly, taking into account their specific sensory and cognitive requirements. Other factors that need to be considered are e.g. the ability of a foreign user to understand the local language. While the design guidelines col

18、lected in the present document are expected to benefit primarily users with special sensory or cognitive requirements they are equally relevant for user in situations in which environmental factors exclude the use of specific modalities (e.g. spoken language in a very noisy environment) or in which

19、the users are not able to interpret specific presentation of information (e.g. written alert messages while driving a vehicle). ETSI ETSI TR 103 335 V1.1.1 (2017-04) 5 1 Scope The present document provides user interface design guidelines applicable to alert messages which allow users with disabilit

20、ies to become aware of alert messages and to access the contents of such messages. These guidelines cover the presentation of alert messages. The contents of alert messages is not in the scope of the present document. 2 References 2.1 Normative references Normative references are not applicable in t

Anna is a 76 years old woman who lives by herself in a village just 20 km away from the city. She is Daniela

38、s mother and the Maxs grandmother. She uses to take care of Max when he gets out of school the days that Daniela has late shift. Today is normally not such a day, but Daniela called her 3 hours ago, warning Anna that she would most probably be very late today. Anna picked up Max from school at 5 pm

39、and they both went walking to Annas place. Anna is watching TV while waiting for Daniela, as Max is doing his homework in the other room. She gets hungry and goes to the kitchen to prepare a small sandwich. Max is an 8-year-old boy. He is doing his homework at her grandmothers place while waiting fo

41、n with 2 friends through Europe with an Inter-rail ticket. The train arrived to the city 6 minutes ago. Balazs got off the train with his friends and they are all in the platform 7 of the main train station in the city. While Balazs is searching the address of the youth hostel in his mobile phone to

42、 find the shortest walking way, his friends are taking care of the luggage and selecting some drinks from the vending machine in the platform. Balazs has some problems to find the address, because the address was not spelled correctly in his travelling guide. He stops a young girl that is waiting on

43、 the same platform to ask her in English about the way. Balazs speaks Hungarian and some English, but no Spanish or Catalan, the same as his friends. The young girl tries to explain in English and shows Balazs the way on the screen of his mobile phone that currently shows a map of the city. It is qu

44、ite difficult to understand each other on the platform, since a train is just arriving and the noise level is increasing. Irene is a 33-year-old project manager in a big company. She is still sitting in a meeting that should have finished more than one hour ago. She has 3 missed calls from her husba

She is nervous because she knows that John is waiting for her since more than 20 minutes, but she cannot interrupt the discussion now. John is a 34-year-ol

46、d lawyer. He took the afternoon off to coordinate the technical inspection of his vehicle and is currently waiting since more than 20 minutes for his wife Irene, in the bar just around the corner of her office. She is normally well on time, so he is worried and called her already 3 times to figure o

47、ut why she is not showing up, but she did not take the calls. After having tried to call Irene he realizes that he has a lost call from his friend Pere that he did not hear. No surprise, this bar is very noisy. Eric is a 44 year old graphic designer that works in the same company as Irene. He is at
