Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

Coordinatometri e mappe georeferenziate
1. COORDINATOMETRO
E MAPPE GEOREFERENZIATE
Mauro Vannini, www.mondogeo.it
Le caratteristiche principali dei coordinatometri, delle
carte georeferenziate ed il loro uso pratico.

2. Dapositiva 2 Uso del coordinatometro
Il coordinatometro in abbinamento con una carta
Introduzione
Saper usare in modo corretto e rapido le carte
georeferenziate ed il coordinatometro sarà un ottimo aiuto
per muoversi in sicurezza in ambiente specialmente se unite
all’impiego di un palmare gps.
Di seguito verranno illustrate le carte georeferenziate, i
coordinatometri e come impiegarli praticamente.
georeferenziata
permettono di leggere le
coordinate di un punto sulla carta
stessa.
L’uso corretto di questa
metodologia sono un valido ausilio
per l’orientamento in ambiente.
3. Viceversa, note le coordinate di un
punto, possiamo identificarlo sulla
carta.
Dapositiva 3 Uso del coordinatometro
Se abbiamo una carta georeferenziata
ed un coordinatometro con la stessa
scala siamo in grado di rilevare in
modo accurato le coordinate dei
punti dalla carta.
Utilità del coordinatometro e della carta georeferenziata
Ad esempio se identifichiamo una fonte d’acqua sulla carta possiamo
rilevarne le coordinate ed una volta inserite nel gps ricercarla in
ambiente.
Se ci fossimo persi possiamo rilevare con il gps le coordinate di dove
siamo e ricercare poi il punto sulla carta per poterci orientare.
4. Elementi caratteristici della carta georeferenziata
In una carta
georeferenziata devono
essere indicati:
La scala.
Il datum geodetico,
la proiezione, il fuso
e la fascia
Il reticolo
cartografico con
indicate le relative
coordinate.
Nota: a volte l’indicazioni di
fascia e proiezione vengono
omesse.
Dapositiva 4 Uso del coordinatometro
5. Significato pratico della georeferensiazione delle carte
In una carta
georeferenziata ogni
punto sulla carta
corrisponde ad un
punto identificabile in
modo semplice e
preciso nell’ambiente
reale
tramite le
proprie
coordinate.
Dapositiva 5 Uso del coordinatometro
6. Dapositiva 6 Uso del coordinatometro
Il coordinatometro è un regolo con assi
graduati orizzontali e verticali realizzato su
supporto opaco o trasparente.
Ogni coordinatometro è realizzato per una
scala ben precisa e questa deve
corrispondere alla scala della carta su cui
verrà usato.
Il coordinatometro
Questo strumento viene impiegato
per determinare in modo preciso le
coordinate di un punto all’interno
del quadrato del reticolo
cartografico.
Le tipologie principali di
coordinatometro sono quattro
descritte di seguito.
7. Dapositiva 7 Uso del coordinatometro
Adatto solo per supporti trasparenti.
Permette la lettura anche in prossimità
dei bordi della carta.
Preciso, i lati orizzontali si
sovrappongono al reticolo garantendo il
parallelismo.
La scala verticale copre il punto da
rilevare rendendone più difficoltosa
l’identificazione.
Primo tipo di coordinatometro, ad «H» rovesciata
Si sovrappone l’asse verticale al punto mantenendo gli assi orizzontali sovrapposti alle
linee del reticolo.
Latitudine Nord: 600 m
Si legge dove l’asse verticale dove si sovrappone al punto da rilevare.
Longitudine Est: 750 m
Si legge dove gli assi orizzontali incrociano le righe verticali del reticolo.
8. Dapositiva 8 Uso del coordinatometro
Adatto sia per supporti trasparenti che
per cartoncino opaco.
Non permette la lettura in prossimità
del bordo carta.
Abbastanza preciso, il lato orizzontale si
sovrappone alla linea di reticolo.
La scala verticale copre il punto da
rilevare rendendone più difficoltosa
l’identificazione.
Secondo tipo di coordinatometro
Si sovrappone l’asse verticale al punto mantenendo l’asse orizzontale sovrapposto alla
linea di reticolo.
Latitudine Nord: 600 m
Si legge dove l’asse verticale dove si sovrappone al punto da rilevare.
Longitudine Est: 750 m
Si legge dove l’asse orizzontale incrocia la riga verticale del reticolo.
9. Dapositiva 9 Uso del coordinatometro
Adatto solo per supporti trasparenti.
Permette la lettura anche in prossimità
del bordo carta.
Impreciso, nessuna sovrapposizione per
mantenere gli assi paralleli al reticolo.
Intuitivo, il punto da rilevare va
collimato al centro della croce.
Terzo tipo di coordinatometro, a «croce»
Si collima il punto al centro della croce mantenendo gli assi paralleli al reticolo.
Latitudine Nord: 600 m
Si legge dove gli assi verticali incrociano le righe orizzontali del reticolo
Longitudine Est: 750 m
Si legge dove gli assi orizzontali incrociano le righe verticali del reticolo.
10. Dapositiva 10 Uso del coordinatometro
Adatto sia per supporti trasparenti che
per cartoncino opaco.
Non permette la lettura in prossimità
del bordo carta.
Impreciso, nessuna sovrapposizione per
mantenere gli assi paralleli al reticolo.
Intuitivo, il punto da rilevare deve
trovarsi nel vertice in alto a destra.
Si collima il punto nell’angolo in alto a destra del coordinatometro.
Latitudine Nord: 600 m
Si legge dove l’asse verticale incrocia la riga orizzontale del reticolo
Longitudine Est: 750 m
Si legge dove l’asse orizzontale incrocia la riga verticale del reticolo.
Quarto tipo di coordinatometro
11. Le coordinate di un punto
Ogni punto si identifica
dalle proprie coordinate.
Per fornire le coordinate
(complete) occorre
indicare:
• Datum geodetico
• Sistema di proiezione
• Latitudine Nord, Ln
• Longitudine Est, Le
• Fuso
• Fascia
Per una corretta
indicazione occorre
specificare tutti i
parametri.
Dapositiva 11 Uso del coordinatometro
12. Lettura delle coordinate di un punto dalla carta 1 di 3
Rilievo delle coordinate del
punto L (Le, Ln):
1° passo
• Si identifica il quadrato
del reticolo cartografico
dove giace il punto L.
Si considera il punto base
Q, l’angolo in basso a
sinistra del quadrato.
• Si leggono sul bordo
carta, seguendo le linee
del reticolo, le coordinate
del punto Q (Qe, Qn).
Qe = 528.000 m
Qn = 4.863.000 m
Dapositiva 12 Uso del coordinatometro
13. Dapositiva 13 Uso del coordinatometro
Lettura delle coordinate di un punto dalla carta 2 di 3
2° passo
• Usando il
coordinatometro si
rilevano le coordinate del
punto L relativamente al
quadrato in cui si trova.
Lqe = 700 m
Lqn = 800 m
14. Dapositiva 14 Uso del coordinatometro
Lettura delle coordinate di un punto dalla carta 3 di 3
3° passo
• Si calcolano le coordinate
sommando i valori
trovati:
Le=Qe+Lqe = 528.000+700
Le=528.700 m
Ln=Qn+Lqn = 4.863.000+800
Ln=4.863.800 m
Le coordinate complete di
C.sa Lagoni quindi sono:
WGS84-UTM, Fuso 32
Lon. Est: 528700 m
Lat. Nord: 4863800 m
15. Determinazione di un punto sulla carta note le coordinate.
Dapositiva 15 Uso del coordinatometro
Note le coordinate di un punto P possiamo identificarlo su carta.
1) Procurarsi una carta georeferenziata della zona
in oggetto.
2) Identificare il quadrato in qui giace il punto P
3) Utilizzando il coordinatometro determinare il
punto P all’interno del quadrato.
NOTA: Se il Datum geodetico delle coordinate date fosse diverso da quello della carta a
disposizione occorre provvedere a convertire le coordinate nel datum della carta.
Esempio
Coordinate del punto P: Lon. Est: 735 685 m, Lat. Nord: 4 458 934 m, ED1950, F33.
Si identifica il punto Q, base del quadrato dove giace P, con coordinate 735 000 Est e
4 458 000 Nord sulla carta (dalle coordinate si tolgono decine e centinaia di metri).
Trovato il quadrato in oggetto si considera solo le coordinate interne ad esso, unità,
decine e centinaia di metri: 685 Est e 934 Nord. Spostando il coordinatometro
all’interno del quadrato in oggetto facciamo corrispondere il valore delle coordinate
date con la posizione del coordinatometro stesso ed in questo modo identifichiamo il
punto cercato.

17. Errori più frequenti:
RIOTORTO
Errore di Datum geodetico (WGS84 con ED50 e viceversa):
Solo ED50 e WGS84 possono essere confusi fra loro.
Gauss Boaga ha il formato della longitudine completamente diverso e non
confondibile con gli altri due.
Confondere WGS84 con ED50 vuol dire compiere un errore di centinaia di
metri. Questo errore varia a seconda della zona dove siamo.
Errore di Fuso (32 con 33 e viceversa):
Possono essere confusi solo in WGS84 ed
ED50 e non in Gauss Boaga in quanto ha il
formato della longitudine diverso fra i due fusi.
Confondere in WGS84 o ED50 il fuso 32 con 33
vuol dire compiere un errore di circa 700 Km
(valore variabile a seconda della posizione)
A lato i due punti hanno stessa Latitudine e
Longitudine ma uno è nel fuso 32 ed uno nel
fuso 33.
