**3. Results**

As presented in Figure 2, the research at the indicative level was conducted on an unrepresentative group, and therefore its results could not be generalized, as they refer only to the opinion of the group participating in the research. In the future, the study can be repeated in cooperation with sociologists, which will allow to select a methodologically correct research sample and to make the generalization of results. It seems that brainstorming in terms of the number of generated ideas is an effective method [46,57]. In the study, 24 people submitted 348 ideas on a given topic within 55 min. The team working most effectively in terms of quantity generated 70 ideas, and the smallest number of ideas submitted by a 4-person team was 42. The situation was different when assessing to the quality of the generated ideas. The ideas which satisfied the key condition of the research, i.e., a reference to architecture, could be assessed as rather conservative, and replicating what is known from reality. They are quoted and discussed below.

### *3.1. Results of Research*

The results of the research will be discussed merely as some tendencies in the formulation of answers to the stated research problem.

### 3.1.1. Urban Information

With regard to urban information, the students proposed "information points as urban accents in stopover places; horizontal signs—arrows, changing surface textures for the blind; simple, legible and consistent visual messages; maps of the city with our location; city districts identified by colors; avoiding excessive visual information on digital displays; avoiding sound reverberation, echo, understandable information transfer (in relation to hearing)"; as part of the "smart" solutions, the idea of "a communication assistant: senior robot" was proposed.

### 3.1.2. Communication and Transport-Public and Individual

In the field of communication and public or individual transport, the following was proposed: "roofed, lit, closable stops (protection against wind), with ergonomic seats and places for shopping bags, walking sticks, crutches, walkers, pets; moving walkways in popular public places, or quiet traffic paths separated from faster traffic paths (separating people being in a hurry from people who walk)"; in the area of "smart" solutions, the idea of "drones distributing mail or medicines ordered from the pharmacy" was proposed.

### 3.1.3. Forms of Residential Housing

The proposed forms of housing for seniors in a smart city are identical to the already existing solutions: "old age homes connected to an orphanage or kindergarten (preventing loneliness), multi-generational housing estates; ground floors for seniors, multifunctional facilities, a residential complex containing services, medical and entertainment functions; community centers, gardens for common cultivation; common areas; places encouraging intergenerational integration; all flats should be flexible (for able-bodied and disabled people); color marking of buildings-better orientation; elevators, ramps in every building; senior cohousing"; "smart" solutions comprise: "fingerprint-activated door opening; flats equipped with buttons to activate assistance (neighborly, medical)".

### 3.1.4. Accessibility of Buildings

In the field of building accessibility, students reported conservative ideas such as: "no architectural barriers; clear marking of entrances; designing kitchen systems which are mobile and adapted for people in wheelchairs (e.g., the possibility of rolling the wheelchair under the worktop)", and more audacious ones: "antigravity domes, teleporting; mobile buildings".
