She barks out instructions to the stone, to will it into the house, and gets annoyed when it stops outside the circle.
Schori (27) has a successful international record, with the highlights being gold medals in the world mixed doubles with Toni Mueller in 2008 and 2009. She was also a member of the Swiss team that finished fourth at the Vancouver Winter Olympics last year.
The first world title in Finland was special.
"It was the most exciting thing I've ever done," she said.
"It was the first time I'd played in international curling. It was so exciting to win first time up."
It became even better in Italy the following year, when the Swiss combination retained its world title.
"I didn't think we'd win it twice. It was awesome."
Schori, who works for a security company in Zurich, is now an established international. She was a member of the Swiss women's team at the Vancouver Olympics, which finished third in the European championships last year.
Schori followed her older sister Brigette into the sport when she was aged 7.
There is always pressure on Schori to perform.
"There are always people there to help you," she said.
"Curling is a team sport and we are just like one big family."
She was invited to New Zealand for the Winter Games by Scott Becker, who managed the New Zealand mixed doubles team in Russia last year.
She spent five days on holiday in Fiji before coming to the Winter Games in Naseby.
Like most Swiss nationals, she is an accomplished skier.
"But I don't have much time to ski because of my curling commitments," she said.
Switzerland won its last two games of the mixed doubles and will play Japan in the semifinals tomorrow morning.
The Swiss combination of Schori and Reto Seiler beat Japan 11-3 and Latvia 11-1 to finish with five wins.
Five teams finished with five wins - Hungary, New Zealand, Japan, Latvia and Switzerland.
New Zealand will play Latvia today at the Maniototo International Curling Rink and the winner of that game will play Hungary in the semifinal tomorrow morning. The other semifinal is between Switzerland and Japan.
China and Japan are the top teams in the women's competition and China and Korea lead the men's event.
