  You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

  You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
  Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces.

  {"bullet_list": "\u3010What is M22 hud\u3011M22 is a GPS mode flat screen display, unlike most flat screen displays on the market, our designers have made good use of the windscreen to turn M22 into a new windscreen HUD. \u3010Design Concept\u3011This GPS speedometer is a novel design with a colour scheme for the first time. It presents important speed data to the driver at a glance and is simple to understand. \u3010Main Functions\u3011The M22windshield speedometer projector displays speed, clock, travel time and distance travelled. It also has an over speed alarm function and a GPS compass to show the direction\uff08The compass needs to locate the satellite before it can be used. You can try moving the car to an open road surface.\uff09. Speed is available in MPH and KM/H, which can be adjusted in the settings. When there is an over speed, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always reminding the driver to pay attention to driving safety, placing a beautiful M22 HUD in the car. \u3010Automated HUD\u3011The advantage of the digital speedometer automation is that it turns on automatically when the car starts and turns off automatically when the car is switched off, which is very convenient and you don't have to worry about the product not being able to turn off. A gentle reminder, if you are not driving for more than a week, please remove the product and put it in the drawer. \u3010Instructions for use\u3011 Our product is easy to install, plug and play, just use the usb cable included in the product to connect the car and the product, start the engine to power on and use. When you notice the small icon on the product flashing continuously, it means the product is collecting satellites, the speed will only be displayed when the device searches for satellites. \u3010Note\u3011Please note the following three important information, \u2460In garages, overpasses and dense buildings will affect the search speed \u2461When the same GPS device is installed in your car, it will also affect the search speed of this product, i.e. two GPS devices cannot be placed together \u2462When your car has metal film, it will also affect the search speed of this product. \u3010Reminder\u3011Inaccurate speed: Check if the unit is correct, kilometers (KM)/miles (MPH), (refer to the 5 settings for speed unit switching). You can also adjust the vehicle speed, such as the instrument displaying 100 km/h and the machine displaying 105 km/h. Adjust the parameter value to 102. During the day, the data cannot be seen clearly and there is a reflection: stick a reflective film to make the data reflect on the reflective film. You can also enter the fourth setting to adjust the brightness. 0 is the automatic light sensing mode, and 1-11 is the manual adjustment. You can manually increase the brightness."}],

  You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

  You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
  Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces.

  {"bullet_list": "\u3010What is M22 hud\u3011M22 is a GPS mode flat screen display, unlike most flat screen displays on the market, our designers have made good use of the windscreen to turn M22 into a new windscreen HUD. \u3010Design Concept\u3011This GPS speedometer is a novel design with a colour scheme for the first time. It presents important speed data to the driver at a glance and is simple to understand. \u3010Main Functions\u3011The M22windshield speedometer projector displays speed, clock, travel time and distance travelled. It also has an over speed alarm function and a GPS compass to show the direction\uff08The compass needs to locate the satellite before it can be used. You can try moving the car to an open road surface.\uff09. Speed is available in MPH and KM/H, which can be adjusted in the settings. When there is an over speed, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always reminding the driver to pay attention to driving safety, placing a beautiful M22 HUD in the car. \u3010Automated HUD\u3011The advantage of the digital speedometer automation is that it turns on automatically when the car starts and turns off automatically when the car is switched off, which is very convenient and you don't have to worry about the product not being able to turn off. A gentle reminder, if you are not driving for more than a week, please remove the product and put it in the drawer. \u3010Instructions for use\u3011 Our product is easy to install, plug and play, just use the usb cable included in the product to connect the car and the product, start the engine to power on and use. When you notice the small icon on the product flashing continuously, it means the product is collecting satellites, the speed will only be displayed when the device searches for satellites. \u3010Note\u3011Please note the following three important information, \u2460In garages, overpasses and dense buildings will affect the search speed \u2461When the same GPS device is installed in your car, it will also affect the search speed of this product, i.e. two GPS devices cannot be placed together \u2462When your car has metal film, it will also affect the search speed of this product. \u3010Reminder\u3011Inaccurate speed: Check if the unit is correct, kilometers (KM)/miles (MPH), (refer to the 5 settings for speed unit switching). You can also adjust the vehicle speed, such as the instrument displaying 100 km/h and the machine displaying 105 km/h. Adjust the parameter value to 102. During the day, the data cannot be seen clearly and there is a reflection: stick a reflective film to make the data reflect on the reflective film.

  You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

  You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
  Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces.

It presents important speed data to the driver at a glance and is simple to understand. \u3010Main Functions\u3011The M22windshield speedometer projector displays speed, clock, travel time and distance travelled. It also has an over speed alarm function and a GPS compass to show the direction\uff08The compass needs to locate the satellite before it can be used. You can try moving the car to an open road surface.\uff09. Speed is available in MPH and KM/H, which can be adjusted in the settings. When there is an over speed, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always reminding the driver to pay attention to driving safety, placing a beautiful M22 HUD in the car. \u3010Automated HUD\u3011The advantage of the digital speedometer automation is that it turns on automatically when the car starts and turns off automatically when the car is switched off, which is very convenient and you don't have to worry about the product not being able to turn off. A gentle reminder, if you are not driving for more than a week, please remove the product and put it in the drawer. \u3010Instructions for use\u3011 Our product is easy to install, plug and play, just use the usb cable included in the product to connect the car and the product, start the engine to power on and use. When you notice the small icon on the product flashing continuously, it means the product is collecting satellites, the speed will only be displayed when the device searches for satellites. \u3010Note\u3011Please note the following three important information, \u2460In garages, overpasses and dense buildings will affect the search speed \u2461When the same GPS device is installed in your car, it will also affect the search speed of this product, i.e. two GPS devices cannot be placed together \u2462When your car has metal film, it will also affect the search speed of this product. \u3010Reminder\u3011Inaccurate speed: Check if the unit is correct, kilometers (KM)/miles (MPH), (refer to the 5 settings for speed unit switching). You can also adjust the vehicle speed, such as the instrument displaying 100 km/h and the machine displaying 105 km/h. Adjust the parameter value to 102. During the day, the data cannot be seen clearly and there is a reflection: stick a reflective film to make the data reflect on the reflective film. You can also enter the fourth setting to adjust the brightness. 0 is the automatic light sensing mode, and 1-11 is the manual adjustment. You can manually increase the brightness."}],
